Industrial Ethernet networking solutions special report Industrial Ethernet technology provides effective building blocks for corporate and smart manufacturing networks worldwide. In this special report, industry experts provide information on the latest SPE trends, solutions to improve IIoT performance, network convergence and the impact of Time Sensitive Networking.

Factory networks are in a period of rapid innovation offering higher levels of performance driven by SPE/APL, gigabit Ethernet, 5G, TSN, IEC 62443 and more.

INDUSTRIAL ETHERNET NETWORK TECHNOLOGY and infrastructure solutions are in the midst of an expansionary period of new networking solutions, from the device-level to the cloud, that will enable new levels of digital innovation with a goal of transforming global manufacturing.

For our 2022 Industrial Ethernet Showcase, IEB reached out to industry experts to get their insights into the development of the Industrial Ethernet technologies and perspectives on the megatrends shaping and enabling development of industrial networks.

Key technologies include the continued emergence of Single Pair Ethernet and Ethernet-APL, 5G, TSN, Gigabit Ethernet, and new levels of standardization at the device level. Network architectures are going through a period of rapid innovation with the advancement of OPC UA software technology, for example, and the increased need for greater levels of IT-OT convergence and cybersecurity solutions.

Impetus for change

Industrie 4.0 and Industrial Internet of Things “Industrie 4.0 and with it the Industrial Internet of Things are continuously developing

and driving the needs of the future. Edge Computers and IIoT Gateways will have to connect to both, industrial devices and at the same time to the IT, often the cloud,” Lars Jaeger, Head of Product Marketing for Moxa told IEB recently. “This is not an exception anymore, but the rule.”

“Therefore, industrial and IT networks must be open for data pipelines across the entire company infrastructure, including both IT and OT environments, and of course cloud infrastructure. This has to be done in a flexible, yet manageable and secure way.

Jaeger said that Moxa sees the following relevant technical developments contributing to the evolution of Industrial Ethernet factory networks: • Gigabit Ethernet replacing Fast Ethernet, trending towards multiple GbE • Wireless networks using 5G or 802.11ac technology • Integrated network monitoring solutions combining views of both worlds, IT and OT • IEC 62443 becoming the leading cybersecurity standard • SPE/APL will allow for an accelerated integration of current proprietary two-wire installations into Ethernet, and

• Soft evaluations of TSN and OPC UA technology

Technology benefits

Jaeger said that the technical benefits that these new trends are offering in terms of networking solutions are focused in a series of areas.

Gigabit Ethernet trends (1GbE, 2.5GbE, 5GbE, 10GbE): The sheer increase of network nodes, information and new applications can only be solved with more bandwidth.

In addition, GbE provides typically lower network latency leading to better application performance.

5G and 802.11ac: 5G promises several benefits, including stable communication with very little latencies on one hand, and multiple Gbps bandwidth on the other hand, depending on the chosen deployment. 802.11ac is the logical evolution of WLAN technology, and therefore partly backward compatible. More bandwidth, more security, more radio stability with less interferences.

Integrated Network Monitoring: In order to manage a network, all relevant parameters must be at hand. The health of network must be monitored, and quick and easy trouble shooting must be possible from

Industrial Ethernet M12 Power L-code connectors are an extension of the current M12 IEC standard and have been selected by PROFIBUS and PROFINET International as the standard for 24-volt power supply systems used in PROFINET devices. a central control center. Obviously, IT and OT have different needs in terms of network monitoring. Only integrated solutions can provide a holistic view across IT and OT networks.

IEC 62443: Cybersecurity can only work as a holistic concept. From product design, over security product features, to network management, and vulnerability fixing. IEC 62443 is the only standard which provides a defense-in-depth approach.

SPE/APL: Current two-wire, often serial based communication can be easier retrofitted to Ethernet networks by using SPE/APL technology. Expensive infrastructure investments can be reduced.

TSN: Time-sensitive facilitates high-speed networking, large volumes of data transmission, highly accurate motion control, and low latency. TSN can prioritize network traffic, which guarantees real-time communication and means time-critical data will be delivered to the right place at the right time. In other words, the aim of a converged application on one unified network will be accomplished in industrial automation based on standard Ethernet. Eventually, it will be feasible to have one unified network for diversified applications. This eliminates the concern that time-critical data would not reach its destination in time. TSN can also enhance network security because accurate data transmission can be scheduled to avoid the inflow of non-authorized data.

Impact of applications and networking architectures

“The trends to more bandwidth, integrated networking solutions and IEC 62443 are in principle visible across all vertical markets and applications,” Jaeger said. “5G and 802.11ac are currently mostly adopted by Campus networks, AGV/AMR and other logistical

services. SPE/APL is currently mostly discussed in process automation applications.”

But he added that it is the promising features and benefits of TSN that make it indispensable to a wide range of applications that are extensively used across various industries, including semiconductor, automotive, machinery, food and drink, chemical, and power generation. However, each TSN application comes with its specific requirements, and currently there is a substantial gap between existing TSN standards and application-specific TSN systems. Moxa collaborated with Xilinx to make headway in developing time-sensitive networking technologies for Industry 4.0 applications.

He said that the engineering challenges that the newest solutions are designed to address include: • Network connections to more devices and overall, more network bandwidth • Good network management to be able to make all those necessary moves, adds and changes on an ongoing basis • High security standards, so we can be sure the whole IT/OT infrastructure can run reliably for a long time • Open protocol standards to overcome the various silos along the communication pipelines

More power in less space

Focus on the standardization of components According to Sofia Sevastidou, global product manager at TE Connectivity, the key technical trends in industrial networking influencing the development of the latest generation of Industrial Ethernet Networking components fall into two broad categories.

One is the need for more power in less space. As we move toward more data-driven industrial automation, equipment and devices

increasingly demand solutions that can provide the higher levels of power needed to support more data.

“Higher power solutions can easily begin taking up valuable space on the factory floor as more machines are upgraded, so it is important that these solutions are designed with a small profile in mind,” Sevastidou said.

“Amid these evolving expectations, we are seeing the development of more industrial ethernet networking components that deliver higher power in a smaller package to meet both growing power requirements and demand for miniaturization.”

A second important area Sevastidou mentioned is the standardization of components. Innovation in components creates exciting possibilities for industrial Ethernet networking, and standardization across the industry will be key to realizing the full potential of these benefits.

When manufacturers upgrade their equipment and devices, they want to do so with confidence that it will be supported well into the future. Standardization efforts help ensure the industry is working toward solutions that support growing and changing technical demands.

Technology benefits

“The M12 L-code connectors used in industrial ethernet networking are a great example of a component that brings together these two key technical trends,” Sevastidou said.

“This M12 L-code format has been selected

by PROFIBUS and PROFINET International as the standard for 24-volt power supply systems used in PROFINET devices. This standard helps answer the growing need for components that deliver higher power in a smaller package.”

TE Connectivity (TE) recently launched its M12 L-code cable assemblies, which are an extension of the current M12 IEC standard.

These solutions handle up to 16 A power per pin – the highest in our M12 family – delivering four times the power of standard M12 connectors.

Since they use up to 40% less space than traditional 7/8” connectors, they also provide an important space savings benefit and support the miniaturization of distribution boxes. As manufacturers work to meet growing demand for productivity, M12 L-code connectors deliver on the reliable and efficient power supply they need.

Specific application & architectures

Sevastidou added that M12 L-code cable assemblies from TE are designed for DC power supplies with 63 V DC / 16 A. Applications that require a high current and low voltage – including fieldbus ethernet I/O boxes, ethernet systems, network devices, motors and drives and valve applications – stand to benefit from the L-coding version. With an IP67-rating,

help allow for better identification of parts and to protect against mismatching.

Focus on network connectivity Future-proof edge connectivity options

According to Michael Vermeer, Engineering Strategy Manager for Panduit Corp., some of the main technical trends for industrial networking stem from the need to improve the efficiency of automated systems.

“Enterprises are re-architecting their plants around Industry 4.0 ideals, which require them to improve and ideally automate the network connectivity and management between each system within the plant,” Vermeer told IEB recently. “As result, some of the main technical trends that we are seeing are a renewed focus on structured cabling systems and fiber optics in the plant backbone, and the interest in future-proofing edge connectivity for the advent of single pair ethernet edge communications.”

Importance of Single Pair Ethernet

Vermeer said we need to dive a little deeper into Single Pair Ethernet, since it is one of the latest technical advances. Thinking in the context of the ISA-95 model, levels 2 through 5 of industrial plants already use a significant

amount of IP networking technology. However, these same plants at Levels 0 and 1 use very little Ethernet, instead relying on serial and analog technologies that have been around from the earliest days of automation. These are the applications that IEEE was targeting when they spent the past 5 years developing and validating what was released in 2019 as IEEE 802.3cg. This standard specified the physical layer for ethernet communications over a single twisted pair of conductors.

“Industry 4.0 operations need effective connectivity between every subsystem within the plant. IEEE 802.3cg Single Pair Ethernet enables Industry 4.0, by making this connectivity automated and seamless,” Vermeer added. “Today, stateof-the-art systems use gateways to enable communication and context to flow between a myriad of ethernet, serial, and analog devices. When these devices connect using Single Pair Ethernet, data can flow seamlessly according to centralized network management and security rules, instead of individually programmed gateways.”

He noted that the best part of this is that the conversion from analog to Ethernet can take place on the same type of medium that has been used for serial and analog communications for decades: a single twisted

the new M12 L-code cable assemblies are also designed for use in harsh or wet industrial environments in factory automation.

M12 L-code connectors are designed to address the challenges engineers face as they work to fit more power in a small profile. The M12 L-code cable assemblies from TE offer a conductor size from 1.5 mm² up to 2.5 mm² and handle up to 16A power per pin, which enables a more compact build of a high-power solution for automation devices.

According to Sevastidou, these solutions also offer the flexibility engineers need when designing for various applications and industrial settings. The L-coding version from TE is available in both male and female connectors and is highly configurable with numerous connector variations, cable lengths and wire sizes, providing the versatility engineers need in their designs.

As an IP67-rated solution, TE’s M12 L-code cable assemblies also offer the ruggedness needed to resist varying conditions. These solutions are virtually protected from dust and resist temporary submersion in water at depths of up to 1 meter for 30 minutes.

M12 L-code cable assemblies are also designed for simpler assembly. They follow the color-coding system that has been introduced

Importance of cybersecurity

IT-OT emphasis on flexible and secure access

In order to manage a network, all relevant parameters must be at hand. The health of network must be monitored, and easy trouble shooting must be possible. pair of conductors. Cable requirements for Single Pair Ethernet are a little more stringent, which is to be expected since it delivers 10 Mb/s up to 1Km, which is 300x the bandwidth delivered by fieldbus. Meeting this challenge, field testing is available to validate the physical infrastructure before any devices are plugged in; this has the additional advantage of reducing potential for debug time related to physical infrastructure problems.

automation applications, such as the use of BACnet MS/TP in building automation, are also ripe for this future-proofing effort.

By upgrading their serial and analog cable specifications to those that meet Single Pair Ethernet requirements by TIA or IEC, building owners and operators can have confidence that their physical infrastructure is ready for supporting the next generation of smart building devices.

Application focus areas

Delivering value

Some early applications for Single Pair Ethernet deployment leverage the work done by the Ethernet-APL consortium, which has applied the Single Pair Ethernet physical to Industrial process applications. Leveraging the work done by this consortium, customers can begin future proofing their HART, Foundation Fieldbus and PROFIBUS fieldbus installations. Customers currently deploying the above-mentioned systems can easily validate that their systems are performanceready for Single Pair Ethernet, and have a path cleared to upgrade their systems to HART-IP, Foundation Fieldbus HSE, or PROFINET in the future.

Vermeer said that other serial-heavy

for 2- or 4-pair IP connections in these environments.”

“Single Pair Ethernet brings Ethernet to the edge, while addressing several issues that have prevented full-scale adoption of ethernet, replacing serial and analog networks. The base capability of Single Pair Ethernet provides for communication over 1Km, 10x the distance of standard ethernet,” Vermeer said. “Single Pair Ethernet does this while providing 10 Mb/s, 300x the bandwidth offered by fieldbus protocols. Also, through the Ethernet-APL consortium Single Pair Ethernet addresses the challenge of bringing ethernet into explosion hazard environments. With this capability of Ethernet-APL, devices can be operated over ethernet without the significant protection measures that would otherwise be required

Sophie Richerzhagen, Product Owner Cybersecurity for Siemens, told IEB that key technical trends are increasingly accompanied by the growing importance of cybersecurity for industry.

“This field is already influencing the development of devices and services in the industrial market, and has only been accelerated by the mobile working explosion from the last 24 months. In the office/ IT (Information Technology) world, mobile working in general has long been established, but there is also a growing demand for more flexible and secure access to systems and applications in operational technology (OT),” Richerzhagen stated.

The benefits of enterprise-wide access to industrial applications have created an increasing demand for cybersecurity solutions that tackle the different requirements of OT and IT. In IT, the Zero Trust security model has proved effective for networks with dynamic pools of devices; a concept in which every user and device must continuously prove their identity and integrity, whether within the network perimeter or not. In contrast, the perimeter-based industrial security concept as part of Defense-in-Depth according to IEC 62443 is used to protect OT systems with industrial communication networks that have grown over years.

Siemens, a leading provider in the field of industrial automation, and Zscaler Inc., a leading provider in the field of Zero Trust, have expanded the Defense-in-Depth OT concept to be additionally secured by Zero Trust principles. In combination with the existing OT security mechanisms, this allows implementation of a granular access concept.

“With this fundamental protection, companies can offer new products and services based on their existing technology.

For instance, secure IT/OT integration within Siemens has provided manufacturing with remote access to X-ray inspection systems for faster diagnostics. Similarly, quality assurance engineers can also tunnel into their operative manufacturing processes for preventative inspection or faster resolution of acute issues.

Cybersecurity for industry is underpinning the larger digitalization use-cases that Industry 4.0 has brought to the forefront,” Richerzhagen added.

Networking architectures

Conceptually, Richerzhagen said that cybersecurity for Industry is branchindependent. The feature and function sets are applicable to all digitized automation

Fully switched networks

Eliminating collisions and improved determinism Dr. Al Beydoun, President and Executive Director at ODVA, said that key technical trends in industrial networking are influencing the development of the latest generation of Industrial Ethernet Networking components.

Artificial intelligence and machine learning algorithms enabled by lower cost edge computing power and increased connectivity are powering new network/security appliances that can enhance security through deep packet inspection, intrusion monitoring, and easier to manage access control,” Beydoun said.

“Security visibility is an important part of a defense in depth approach given that network switches can be a key link in both enabling IIoT applications as well as detecting and identifying bad actors within OT networks.

Another key component of defense in depth security is proper network design and planning 04.202 2

processes. Factory and process automation are particularly exciting as they offer large levers for value generation within a company.

It offers the possibility to tie the customer directly into the manufacturing process – the keystone of the industrial value chain. This translates to order management, logistics, purchasing, quality assurance and ideally right down to sales.

“The automation sector has flourished under the flexibility and scalability to design innovative and unique solutions for their field.

Creating a cybersecurity solution to protect their productivity while holding compliance to the newest cybersecurity regulations is the challenge ahead. To date, overlayed security solutions offer customers a boost to their security but creates a patch work solution with high administration overhead and low scalability,” she added.

The newest solutions from Siemens are aiming to integrate this cybersecurity performance down to the automation level and not just for new installations. The goal is to work with brownfield installations, giving successful applications the cybersecurity model to extend their product lifecycle. It is about rediscovering the flexibility in the manufacturing process and extending it with industrial cybersecurity.

Already existing security concepts based on SCALANCE SC devices can now be supplemented by the simple installation of the cloud-based remote access service Zscaler Private Access as a docker container on the SCALANCE LPE (local processing engine). This combination of the well established in OT Defense in Depth and the IT driven Zero Trust model creates a secure access solution for industrial environments.

In addition, production requirements for availability and real-time capabilities continue to be met.

A fully switched network eliminates collisions and improves deterministic behavior of networks such as EtherNet/IP. The addition of secure zones and conduits per the ISA/IEC 62443 security standards provides a way to segment and zone sub-systems in a control network. with segmented networks with vertically layered switches.”

Beydoun said that, in the same way that sea going vessels have compartments that can be sealed in case of a hull breach, having a network with security zones can help to contain an intrusion from impacting too much of the larger system. This design ensures that a failure in one zone or within one switch doesn’t affect the entire operation. Local security intelligence within network switches can help identify threats that are directly encountered.

“Once the threat is identified via deep packet inspection the metadata can be sent to a cybersecurity device to help mitigate the threat. Firewalls can also do deep packet inspection and prevent threats based on firewall policies. Cloud based data analysis can also help to identify larger scale trends and actions that are out of place that can then be translated into action within the local area,” he added.

Key technical benefits

Beydoun’s view is that a fully switched network eliminates collisions and improves deterministic behavior of networks such as EtherNet/IP. The addition of secure zones and conduits per the ISA/IEC 62443 security standards provides a way to segment and zone sub-systems in a control network. Zones can be defined by groups of nodes that have similar functional and security requirements.

Examples of a similar security requirements include devices that are all in the same functional area (e.g. packaging), contain intellectual property, enable motion, or control environmentally sensitive materials.

A secure conduit is the interlinking of the different security zones.

He added that it’s critical to ensure that the communication paths between zones are access controlled, are resistant to denial-of-service

i n d u str i a l e th e r n e t b o o k

attacks, and can ensure that they don’t allow a compromised zone spread to the broader network. VLANs are a way to improve security and contain broadcast messaging as a part of implementing secure zones and conduits.

Network configuration such as implementing Quality of Service (QoS) traffic prioritization to ensure time critical control traffic isn’t held up and use of IGMP snooping to control multicast messages to reduce network congestion can help to optimize properly segmented networks.

Networking solutions

“Implementing the networking concept of secure zones and conduits via network switches is broadly applicable in the automation space given that IIoT connectivity offers quality improvement, waste reduction, and throughput acceleration opportunities across both discrete, hybrid and process industries,” Beydoun said. “However, certain applications are particularly important to segment such as motion equipment that workers are in near proximity to such as collaborative robotics or zoned safety applications where light curtains stop the movement of potentially dangerous machinery when a worker gets to close.”

Other vital areas to protect include operations that could reveal confidential recipes, manufacturing processes, or other valuable information that provides for a competitive advantage. Processes that involve corrosive chemicals or extremely rare earth metals are also in need of special segmentation to both protect the environment and to manage financial risk.

Once these more sensitive zones are identified and segmented, additional security measures can be implemented such as CIP Security at the device level for policy-based access control. Following the ISA/IEC 62443 defense in depth and secure zone and conduit approach can help to deter bad actors from attempting to infiltrate and attack a facility.

“Enabling IIoT and Industry 4.0 applications within plants and factories allows for a whole new world of possibilities through prognostic failure detection, automatic spare reordering, new product development feedback loops via digital twins and so forth,” Beydoun concluded. “Single Pair Ethernet solutions such as Ethernet-APL in process and EtherNet/ IP Resource-Constrained Device connectivity in both discrete and process are helping to add more intelligent devices to the network thereby opening up this data for cloud connectivity and analysis.”

He said, however, that this potential improvement in the bottom line through production optimization stands opposed to the new paths that bad actors now have to attack critical infrastructure for monetary gain via ransomware attacks. While network segmentation has always been a best practice for optimal control network operation and prioritization of key traffic, such as CIP Safety over EtherNet/IP, the introduction of cloud connectivity has made it imperative that secure zones and conduits are implemented according to ISA/IEC 62443 to protect operations and allow for device level security, such as CIP Security, to provide a last layer of protection where it’s needed the most.

Secure zones and conduits allow for not only an optimized network and improved security, but also does so in a way that can reduce cost by enabling the highest levels of security to be implemented in a surgical manner to cover the most critical zones.

OPC UA, TSN and SPE

Technology solutions enhance networks According to Ralf Moebus, Head of Product Management, Industrial Communication for LAPP, a number of key technologies are working together to influence the development of Industrial Ethernet networks.

Standardization & interoperability using OPC/UA and TSN

“In the past there had been several fieldbus systems that are incompatible to each other.

This causes high effort in engineering of Industrial Control Systems and system integration of machinery,” Moebus told IEB recently. “Engineers need to know about many different communication technologies, and they have high effort for programming translations from one protocol to another.

This problem was not completely solved with the introduction of Industrial Ethernet. Today with Ethernet mainly the physical layer is standardized: Cables, Connectors and Switches are standard Ethernet components, but there are still multiple in-compatible Industrial protocols in use.”

He added that, with the introduction

Addressing engineering challenges

The future of industrial networks will be continuing to emphasize higher performance and sophistication with support required for new innovations such as artificial intelligence and virtual reality. of OPC/UA, the problem of incompatible protocols can be solved. With OPC UA Field level communication, there is also a solution for Field Device Communication available.

A second important technology which will help for standardization is TSN (Time Sensitive Networking) and it is harmonizing perfectly with OPC UA. “Industrial Ethernet can be found today already in many factories and provides access to a lot of data which is needed for smarter decisions, faster maintenance of machines or more flexible productions. But there is still a lot of data which cannot be accessed from all systems. This can be solved with new physical layer technologies like Single Pair Ethernet,” Moebus said.

OPC/UA

OPC/UA is standardizing the communication for Machine to Machine, Machine to MES and ERP systems or even the cloud. OPC UA is standardizing the communication for Machine to Machine, Machine to MES and ERP systems or even the cloud With OPC /UA Field

level communication there is also a solution for Field Device Communication available.

With OPC UA there is a real manufacturer independent protocol standard available. The user has the benefit that they can ensure the communication between all these devices and machines without the need to program translations between different protocols – saving time and effort. Also, they don´t need to learn different communication standards.

TSN

Moebus stated that TSN is a standardized solution for real time communication and can replace the multiple incompatible realtime communication technologies of today’s Ethernet networks.

He said that TSN has real time capabilities that are suitable for time critical information like control system communication or drive system synchronization. The greatest benefit is that it uses standardized manufacturer independent mechanisms that can be integrated in the network infrastructure and end-devices. The user has the benefit that

in d u s t r ial et h er ne t b o o k

04.2022

Single Pair Ethernet

“Most sensors and actuators are not directly connected to Ethernet. Some reasons are high installation effort, too expensive or the devices are too small for existing Ethernet connectivity solutions,” Moebus added. “With Single Pair Ethernet comes a new technology which lowers these obstacles. SPE needs only one pair of copper cores where today are 4 or 8 cores are needed. Also, it enhances the reach of copper-based Ethernet from 100m to up to 1000m, which gives more freedom in the network design. Another important feature is the power supply via data cable, which is also called PoDL (Power over Dataline). Up to 50 W of power are possible. So, it is the perfect solution for connecting sensors and actuators with low effort and space demand.

It integrates sensor/actuators with the rest of the factory network and makes the data accessible.”

He said that OPC/UA and TSN is the standard that is very interesting for production within larger plants, where several machines have to be integrated to a production system. It provides the right mechanisms for Machine-toMachine communication or also for Machine to MES (Manufacturing Execution System). With its integrated Security mechanisms, it is also perfect for machine to Cloud communication.

With OPCs field level communication it is also addressing field devices like control systems and in this relationship TSN is the perfect partner for OPC/UA. Moebus said that Single Pair Ethernet can significantly reduce the installation effort for Ethernet networks, and it is a great solution for the lowest field level, for sensor and actuators.

“It will enhance the existing Ethernet Networks with a better suitable solution for this application area. Looking at today’s communication pyramid, we see conventional Ethernet with Data Rates between 100 Mbit/s up 10 to Gbit/s for Machine-to-Machine communication or Machine to ERP/MES and Supervisory level. On the sensor and actuator level, SPE will win with the already named benefits,” he said.

OPC UA also addresses the integration of operating technology with IT technology (ERP/MES) and data exchange on field level.

It can ensure the standardized data exchange between these systems. Today, engineers have the challenge to connect many incompatible communication systems. They need to know about all these systems and to translate (gateways) between them. This causes a lot of 04.202 2

effort during the complete life cycle: planning, installing and maintenance. This is solved with OPC/UA.

Application advantages

“Today, engineers must handle a lot of different fieldbus technologies and there is still a gap between the Ethernet network and the sensor actuator level,” Moebus said.

“With SPE, engineers don´t need to know about that many technologies; they just need knowledge in Ethernet. With SPE there is a very economical way for connecting Ethernet devices on the field level, which enables to close the gap and gives more freedom in the network design.”

Emergence of SPE

Single Pair Ethernet and ix Industrial technology Horst Messerer, Product/Sales Manager - Data, Network and Bus Technology for Helukabel, told IEB that a key technical trend shaping industrial networking and influencing the development of the latest generation of Industrial Ethernet is Single Pair Ethernet technology.

“Data cables with Single Pair Ethernet technology differ from previous solutions in that they have only one pair of copper wires.

In addition to data transmission via Ethernet, these cables simultaneously enable a power supply to end devices of up to 50 watts Messered told the Industrial Ethernet Book recently.

“Up to now, this required two or even four pairs of wires, depending on the transmission speed and class of power supply. For users, this difference is advantageous in several ways. The cables are both thinner and lighter.

This opens up numerous new application possibilities - even in places where sensor cables or traditional bus systems have been used up to now.”

Messerer said that another trend is the Ethernet interface ix Industrial. This is a plug-in connection that is significantly smaller and, at the same time, more robust than the existing RJ45 standard.

“The ix Industrial is standardised according to IEC 61076-3-124, combines data transmission and power supply in one interface and thus significantly reduces the required installation space for the connection technology. I expect that this technology will replace the RJ45 connector in numerous applications,” he said.

Technology benefits

These new trends are offering numerous technical benefits that are contributing to advanced industrial networking solutions.

“Single Pair Ethernet technology offers numerous advantages compared to the earlier two- and four-pair solutions,” Messerer added.

i n d u str i a l e th e r n e t b o o k

“The cable diameter is reduced by around 25 percent and so is the cable weight by up to 50 percent. Moreover, two cores are of course much easier and faster to connect than four or eight cores – which reduces the effort required for the assembly.”

He said that, in addition, smaller bending radii are possible which creates more flexibility in the laying process. Thanks to PoDL (Power over Data Line), the data cables are also able to handle a power supply of up to 50 watts.

As fewer raw materials are needed, Single Pair Ethernet also has an advantage in terms of being more environmentally friendly. The technology enables the use of Ethernet up to the sensor level and enables a significant speed boost in process automation from the previous 31.25 kBit (Profibus and Foundation Fieldbus) to 10 Mbit with the SPE 10BASE-T1L standard.

In regard to ix Industrial technology, it shows its benefits to industrial Ethernet in various ways. Firstly, there is the double locking of the socket and connector with the help of two snap-in hooks, which ensures high shock and vibration resistance.

The connector with ten pins is designed for up to 10 Gbit/s Ethernet thanks to Cat. 6A performance and is also suitable for hybrid cables because of its power transmission option - as well as for bus, Ethernet and control cables. The significantly smaller construction space also allows devices to be designed in smaller sizes.

Industrial Ethernet

planning, building and maintaining industrial control system networks will be much easier.

From an economical perspective there is cost reduction potential since the users can choose from a multitude of devices from different suppliers.

Applications focus

Messerer said that SPE is targeting specific application areas and networking architectures.

Single Pair Ethernet is suitable for use in cobots, for example, where particularly thin, flexible and movable cables are required. The technology enables smaller cross-sections and tighter bending radii, which is ideal for the limited space in cobots.

In the automotive industry, SPE ensures a weight saving of about 35 percent in cabling which is a significant cost factor especially in railway vehicles. And in industrial automation, as well, Ethernet can open up completely new applications with SPE, as it closes the gap between the control level and sensor-actuator networks. Thus, the field level and all its participants become real-time capable, smart and part of the IIoT. “The ix Industrial connector is suitable for applications where the dimensions of the classic RJ45 socket on the device are problematic or, for example, where a higher vibration resistance is required,” Messerer said. “But this technology also opens up areas of application wherever hybrid solutions release potential by eliminating the need for a cable.”

Prepared for the future with seamless data transparency SOURCE: BECKHOFF

TwinCAT 3 IoT Data Agent feeds the data lake at Wienerberger AG. In the digitalization initiative, the Group started sending several million measured values to the cloud every day for analysis, to derive actionable insights in all areas of the company as a basis for targeted optimization measures.

IN GLOBALLY COMPETITIVE MANUFACTURING, every minute of time, every gram of raw material and every kilowatt-hour of energy counts. The Wienerberger Group has faced this challenge for decades. But recently, this leading international supplier of innovative building materials and infrastructure solutions and, according to the corporation, the world's top brick producer, has leveraged TwinCAT and “Data Agent support” to achieve these goals.

In the course of a comprehensive digitalization initiative, the Group has started sending several million measured values to the cloud every day for analysis to derive actionable insights in all areas of the company as a basis for targeted optimization measures.

In energy-efficient buildings, safe sewer systems, and attractive public spaces, evidence of the Wienerberger Group's expertise can be found in all areas of life. The Viennabased producer of bricks, pipe systems and surface pavers, whose roots go back to 1819, has been successfully driving the future of building for 200 years.

With 197 production sites in 29 countries, the group is one of the leading international suppliers of building materials and infrastructure solutions. In order to be able to defend this pioneering position even in times of increasingly tougher global competition, the Group launched a comprehensive

“Our vision is to create a digital twin of every production line in which not only process, planning and quality data are stored, but also, for example, detailed training course information for system operators,” explained Roy Sibbald, manufacturing excellence officer at Wienerberger subsidiary Pipelife. Ultimately, he wants to know about every single minute of production, and whether this period of time was used productively or not.

“If not, it wasn't a good minute. The same goes for every gram of raw material we use. Was this turned into something that we could sell or what happened to it? The value of reliable answers to all these questions is enormous,” explains the expert, who, according to Manfred Heger, head of IT strategy, innovation & projects at Wienerberger, made a significant contribution to advancing digitization in the production environment.

Accordingly, the way in which the individual machines are integrated into the Internet of Things network has also been standardized and specified by the project managers. An ultracompact C6030 Industrial PC from Beckhoff plays a central role as gatekeeper to the Azure IoT hub in the cloud. Its compact design and a multi-core processor performance of up to 3.6 GHz per core make it the perfect edge device, as Lukas Pechhacker, managing director of HEAP Engineering, explains: “This is the advantage of PC-based control technology – the control devices can be scaled to requirements and offer sufficient performance reserves for data pre-processing on site. In the case of winders, for example, the sampling intervals are in the millisecond range. That's why edge computing is used here to translate into revolutions per minute in order to keep the flow of information to the cloud in check.”

The C6030 with TwinCAT 3 IoT Data Agent generally has to take on many “interpreter” functions: on the one hand, it uses TwinCAT ADS and OPC UA to build communication bridges between machines of different ages and different origins, and on the other hand, it acts as a gateway to the cloud.

countries, we are dealing with an extremely heterogeneous machine landscape and numerous protocols that have to be brought down to a common denominator. In some cases, EL6001 EtherCAT Terminals are required as serial RS232 interfaces to establish the required connections; in others, this works via OPC UA,” explained Pechhacker.

Focus on teamwork

As Beckhoff solution providers, both HEAP Engineering and TietoEVRY understand how to fully leverage the possibilities of PC- and EtherCAT-based control technology. “Everyone on our project team can simply trust that the other person knows exactly what they are doing and that they always keep an eye

on the big picture in everything they do,” said Manfred Heger. Due to coronavirusrelated travel restrictions, two production sites were even remotely connected to the loT network – one in Sweden and the other in the Netherlands. “The local electricians provided the crucial details about the existing infrastructure. Then the required components were ordered from Beckhoff and preconfigured

by HEAP Engineering to allow for simple plugand-play connection on site. Then HEAP Engineering stepped back in to perform the final configuration via a secure remote connection, and we set the appropriate course in the cloud or took care of the data quality checks,” said TietoEVRY employee Manuel Hausjell, describing the collaboration.

“There are always new ideas coming in about what else we could do to improve day-to-day operations in our plants, run benchmarking between the individual sites, achieving quality improvements, supporting predictive maintenance, using fewer resources and much more,” said Sibbald, aware that digitization is an ongoing process. “You can only become lean if valid comparative data is available.

And the beauty our system is that it is easily expandable and scalable,” the manufacturing excellence officer sums up. Additionally, current transformers are being placed more and more frequently in the manufacturing facilities right now because, after all, not only every minute and every gram, but also every kilowatt-hour of energy counts. Thus, the project also makes significant contributions with sustainability goals for the reduction of CO2 as well as energy and raw material consumption. And with the subsequent implementation of QR code recognition, the adaptability of the installed solution has already been proven.

“All we had to do was activate the vision software licenses on the IPC, connect a camera via Ethernet and thereby expand the edge gateway with TwinCAT Vision to include image processing in real time. Of course, the QR codes that have been read are transferred to the cloud with the TwinCAT IoT Data Agent.

The data is also available for use in the MES and ERP system,” said Bezeczky.

Balazs Bezeczky, head of Vienna sales office, Beckhoff.

The good cooperation between the team of experts from the end customer, the system providers and from Beckhoff is crucial for success, especially with comprehensive projects such as this one.

The evolution of control system connectivity SOURCE: CONTEMPORARY CONTROLS

Take a moment to reflect on where we’ve come from to better understand the connectivity technologies that will help you achieve your goals. Beyond the point when we have connected everything to everything, which technologies will win the day? Thriving organizations are the ones who are paying attention to history.

SINCE THE ADVENT OF ELECTRONIC PROCESS control systems, many new technologies have made their way into the industry. Now, we are in the early years of another revolution that is bringing its own innovations and design philosophies. Taking a moment to reflect on where we’ve come from can help us better understand where we are going and which technologies will help us achieve our goals.

Early automation control and communication systems

When the first I/O systems were developed, the standard for control and sensing from the field relied on electromagnetic and pneumatic components, which were subject to physical degradation that limited their lifespan. In the 1960s, engineers generally organized relays into ladders of switching logic that directed electrical flows in a deterministic pattern.

These relay configurations were inflexible and guaranteed to fail after a finite time, leading to the development of solid-state components that operated much more reliably.

Eventually, the same technology was applied to create compact signal sensing inputs, yielding the components needed for a complete digital input/output system. The first PLCs were built using these early I/O components and began making a splash in the automotive industry in the early 1970s.

Around the same time, companies like DEC and Intel were bringing the microprocessor into the mainstream, and their users demanded options for integrating I/O into those systems as well. These high-tech computing systems required further developments in early I/O systems, which offered too little protection for sensitive computer electronics. The first generation of optically isolated digital I/O plug-in module racks quickly became the world standard form factor for computer-based control, allowing automated control to reach many more industries well into the ‘80s.

These parallel bus systems were very fast for the time but suffered from a lack of noise immunity, leading to the first serially addressable I/O. The change yielded greater protection and extended cable lengths but came with a reduction in speed, which in some cases necessitated fundamental changes in the communication architecture. Processorintensive I/O tasks like counting and latching 04.202 2

Today’s edge controllers and I/O systems bridge the OT/IT gap by combining traditional real-time control and sensing functions with communication, storage, security, and data processing functions previously found only in higher-level systems. (pictured: Opto 22’s groov EPIC edge controller, 2019) were embedded in the I/O module to preserve the responsiveness of the system; core communication functions were located in a dedicated co-processor. Distributed control through so-called intelligent I/O allowed control systems to manage many more I/O points without impacting the performance of the central controller.

As I/O modules and I/O processors improved, these early computer-based control solutions were able to offer analog signal processing options, something found only in large distributed control systems (DCSs) at that time. Since early ladder logic—used

by PLCs as a programming language—wasn’t designed to handle analog data formats, this also led to the development of new programming languages.

These early developments exemplify a pattern that has repeated over the past several decades and yielded successively more compact and integrated devices. Later generations of control platforms offered greater computing power “per square inch” as advanced math, programming, and communication functions were incorporated into control boards. Newer generations also continued to combine and

i n d u str i a l e th e r n e t b o o k

embed I/O processing circuitry in different ways. Individual modules expanded from a single I/O channel to upwards of 32 channels, and, in the case of universal I/O today, can even accept a variety of different signal types on a single physical channel.

These technologies have also become available in low-level devices such as I/O modules, sensors and transmitters, and networking components, allowing for the creation of flexible, resilient distributed architectures.

The information revolution

Another pattern apparent from the early generations of control systems is the influence of information technologies on the industry. Even the PLC, marketed as an alternative to early general-purpose computers that were seen as unreliable and difficult to program, wouldn’t have existed without the development of computing technology. And in the 1980s and 90s, as low-cost IBM-PC alternatives began to flood the market, innovations from outside the industrial control market continued to have an influence.

PCs were still the primary control option for

Because it provided the opportunity for tighter integration with business networks, Ethernet spurred another Early PACs provided a wider feature set, including discrete and analog I/O, evolution of the serial communication, and high-level programming languages.

TCP/IP became HMI software to communicate indirectly with the standard for a whole new generation of plant floor hardware by means of an OPC I/O and device communication protocols, server, which housed all the drivers needed to including a then little-known protocol called communicate with those devices. This made it MQTT designed for lightweight machine-tomuch easier for vendors to develop software machine communication. By the time MQTT for industrial systems and improved the found popularity in the early 2010s, other quantity and diversity of data that could be networking advancements had been introduced extracted. OPC continues to be an influential to automation networks, including high-speed interoperability standard today. wireless media and smart wireless devices.

There was also greater interest in closing the gap between automation and business Approaching the tipping point However, the development of OPC did not networks, which led to the introduction of usher in a period of peace and cooperation industrial IoT gateways, and, more recently, among automation vendors, and information edge-oriented controllers and I/O systems. technology was again needed to provide a These devices bridge the gap by combining solution. During a period that came to be traditional real-time control and sensing known as the Fieldbus Wars, vendors took the functions with communication, storage, concept of serial bussed I/O and ran with it security, and data processing functions through various communication media and previously found only in higher-level systems.

This combination of ever more powerful protocols, each attempting to establish their control and networking technologies has combination as the dominant standard.

At the same time, Ethernet was becoming paved the way for modern concepts like the popular in enterprise office environments industrial internet of things (IIoT). And now, and was proposed as a common standard for we are entering a so-called fourth industrial automation as well. Initially, Ethernet was met revolution that aims to harness highly with skepticism by a majority of the industry. connected and distributed automation to But with TCP/IP becoming the standard for finally close the gap with business systems.

Industry 4.0, as it is called, is shining a light on the value and significance of open-source software and long-neglected capabilities like cybersecurity for industrial systems, again drawing on innovations in IT to outfit control systems for the tasks we need them to perform.

Beyond the point when we have connected everything to everything, which technologies will win the day, and where will they take us?

many systems at the time, creating concerns about reliability. It made sense for vendors to develop an industrially hardened alternative, which ultimately crystallized the I/O, networking, and programming components of early hybrid solutions into a cohesive system that would later be called a PAC, or programmable automation controller. Since PACs used the same processors that powered PCs, they were able to offer a feature set that filled a niche between low-cost, PLC-based discrete control and high-dollar, DCS-based process automation.

The PC revolution also led to the popularity of the Microsoft Windows operating system (OS) and broad interest in using its graphical interface to provide a view into what was happening on the plant floor. However, with the expansion of the automation industry in the preceding decades, these early SCADA and HMI developers needed to create a suite of proprietary software drivers to communicate with every device the system might encounter.

It was a time-consuming and expensive process that generally led to very limited driver functionality in the race to expand the available portfolio of supported devices.

In the PC world, a similar trend was occurring in the market for computer peripherals such as printers, and Microsoft had developed a solution that the automation world would later adopt. It began providing device drivers pre-installed into its operating system with a common software interface that developers could use to communicate through those drivers. Instead of building their own drivers to talk to peripherals directly, programmers could talk to Windows, and Windows would talk to the peripherals.

A similar idea using Microsoft’s later Object Linking and Embedding (OLE) technology led it and a small group of automation vendors to develop OLE for Process Control, now, many years later, called Open Platform Communications or OPC. OPC defined a common specification based on a client-server model that allowed Windows-based SCADA/

Custom PoE injector powers explosion-proof CCTV camera SOURCE: CONTEMPORARY CONTROLS

Power over Ethernet (PoE) can adds power along with data to Ethernet wiring, so devices can be powered via standard Ethernet cabling. Eaton used a PoE mid-span injector to provide a compact power source in their CCTV camera housings, saving time and cost by eliminating the need to run separate power wires.

EATON MEDC LTD. RECENTLY USED A MODIFIED version of Contemporary Controls’ Skorpion PoE Mid-Span Injector to provide a compact power source in their CCTV camera housings.

Power over Ethernet solution

Power over Ethernet (PoE) equipment adds power along with data to Ethernet wiring, so devices such as VoIP phones, surveillance and card access machines can be powered via standard Ethernet cabling.

This provides flexibility by allowing the device installation irrespective of the location of an electrical outlet. The use of PoE also saves time and cost by eliminating the need to run separate power wires.

PoE applications require a 48 VDC power source, but most automation systems operate from 24 VAC/VDC power. For Eaton’s application, only one Ethernet Powered Device (PD) needed power, and Contemporary Controls Skorpion PoE injector met this criteria. In addition, Eaton was looking to customize the injector for use in a CCTV camera and reached out to Contemporary Controls for original design manufacturing (ODM).

“The speed of response with which Contemporary Controls modified and then certified the product to fit our needs enabled us to secure more business with our customer,” said Brian Taylor, Product Line and Support Manager CCTV Hazardous Area Communications at Eaton MEDC. Eaton’s CCTV cameras and housings are made from 316L corrosion-resistant stainless steel and are designed for use in harsh environmental conditions and hazardous areas where there is a risk of explosion due to the presence of flammable atmospheres.

They are suitable for a variety of applications both onshore and offshore for the oil and gas, marine, wind, and chemical industries.

Contemporary Controls’ injector is inserted mid-span between a standard Ethernet switch and Ethernet powered device. The injector operates from 24 VAC/VDC and internally generates the 48 VDC PoE power for the powered device — eliminating grounded primary power concerns while providing isolated 15.4 W power output. It injects 48 VDC into the Ethernet cable to provide both 04.202 2

Contemporary Controls’ standard PoE Injector is IEEE 802.3af compliant, UL 508 listed and c-UL certified and comes in its own rugged metal enclosure and metal DIN-rail clip for control panel mounting.

While most customers depend on the rugged metal enclosure to meet the demands of the industrial automation industry, for Eaton, the metal enclosure presented a challenge. Eaton required the completed product to be enclosed in the explosion-proof camera housing without the Skorpion’s metal enclosure.

Eaton tested the standard Skorpion PoE Injector for its operation with the CCTV camera. Next, the team at Contemporary Controls worked with Underwriter Laboratories

(UL) to obtain the necessary approvals for the PoE Injector without its enclosure. This new, compact design fits easily inside the camera housing, and comes certified and applicationready. “We design, develop and manufacture our products in-house, which gives us a huge advantage for ODM projects,” said Bennet Levine, R & D Manager at Contemporary Controls.

“When a customer contacts us about modifying one of our products, we have the resources on hand to deliver a solution, from design to the regulatory approval process.”

Two compact versions

ETHERLINE GUARD is particularly space-saving and slightly larger than a matchbox (49 mm wide, 76.5 mm high and 36 mm deep). The device is operated with 24 V DC, is intended for a temperature range of -40°C to +75°C and is resistant to vibrations and shock in accordance with DIN EN 60529. An easy-to-use SET button is provided to call up a wide range of functions, such as teach-in or to activate the access point.

ETHERLINE GUARD is connected to a data cable node between the critical application or between the cable to be monitored and the controller side. For this purpose, the device has a GUARD/data port for the data cable to be monitored with RJ45 connector, which is routed from the critical application to the device, as well as a DATA port for the data cable with RJ45 connector, which is routed from the device to the controller.

The maintenance data can be transmitted to a higher-level controller by connecting a third data cable to the LAN socket (PM03T variant) or by using the antenna connection for WiFi (PM02TWA variant). Both variants can be configured for cloud communication with MQTT. The external SMA antenna connection guarantees a safe transmission path when the device is in the control cabinet, for example.

The antenna is then simply mounted outside. ETHERLINE GUARD is also equipped with a five-pin terminal for single core wiring.

data cable and specifies it as a percentage.

ETHERLINE GUARD thus contributes to realising a “digital twin” within production facilities by providing important performance forecasts for a data cable. Until now, cables have not been taken into account in these models.

This is based on data from the physical properties and the related data transmission using sensors. The real-time status display enables the wear limit of a cable to be detected and the optimum replacement time to be planned in advance. LAPP especially recommends ETHERLINE GUARD for data cables in accordance with the transmission standard 100BASE-TX (up to 100 Mbit/s) in accordance with IEEE 802.3, but also for EtherCAT, EtherNET/IP and 2-pair PROFINET applications, such as the ETHERLINE TORSION Cat.5 or the ETHERLINE PN Cat.5 FD. These cables are used in many industries in the last few metres or at the process level of an application and are therefore often part of cable chains or torsion-proof cable routing, such as those used in robot arms. ETHERLINE GUARD is ready for mounting on top-hat rails and is intended for installation in control cabinets with protection class IP 20.

To avoid unexpected production downtimes and reduce maintenance costs, Industry 4.0 and digitalisation provide an even more efficient alternative: the concept of predictive maintenance. modulated output signal), which are used to output the cable status.

Easy to put into operation

In addition to the standard LEDs, there are three centrally arranged multi-colour diagnostic LEDs on each RJ45 port: PWR for operational readiness, STATUS for the status of the data cable to be monitored and COM for Connect (LAN version) or WiFi (WiFi version).

The developers at LAPP purposefully only provided simple diagnostic and adjustment options with the device. he ETHERLINE GUARD web interface offers easy and convenient access if a user wants to adjust any further settings or function parameters, or if they want to find out more about the graphic status history for the cable. Here, for example, you can also find the settings for connecting the device to a controller level via MQTT. In addition, the device can be set to a new status using a firmware update if, for example, additional functions are developed and the range of functions are expanded in the future.

ETHERLINE GUARD is easy to put into operation – it requires no expert IT knowledge.

This is carried out using automated and selflearning parameterisation (“teach-in”) in just a few minutes. This starts simply by pressing a button or using the web interface. Another advantage is that no brand-new data cables or changes to the cable design are required for the application. This means that a retrofit into the existing network structure is possible at any time.

ETHERLINE GUARD is available as a cablebound LAN variant "PM03T" and as a wireless WiFi variant "PM02TWA". Thanks to the two variants and the wide range of different connection options, users can decide how

i n d u str i a l e th e r n e t b o o k

the required status information is to be transmitted to the higher-level process level.

The cable status can be identified quickly on the device itself from one of the LEDs visible from all sides. The type of display is based on a traffic light system. It is always lit green when the cable is working perfectly and is within the specifications. If the web interface signals the yellow range or the STATUS LED flashes red, the first signs of wear have already occurred and action is required. The cable should at least be checked in this case and replaced immediately if necessary. If the LED is permanently red, the end of its service life is reached, and now at the latest, data transmission is limited.

Reliable IIoT communication

The patented predictive maintenance algorithms from LAPP make it easy to identify irregularities in the analysed data. The two digital outputs Q1 and Q2 enable the cable status to be output as a switch signal or as a pulse width modulated analogue signal, whereby the alarm threshold for the switch output Q1 can be specified by the user. Both the LAN and WiFi variants can output the cable status via MQTT. The LAN variant has the LAN-RJ 45 connection, while the WiFi variant communicates wirelessly. This guarantees reliable IIoT communication. The data can also be read easily using the access point, for example, with a mobile terminal device. It is also possible to save all data from several years on a (micro) SD card.

The current performance of the data cable is specified in percent for both variants.

ETHERLINE GUARD continuously calculates the cable state and triggers an alarm if the performance or transmission properties of a cable deteriorate and there is a risk of failure.

This includes movement at high speed and acceleration, changing motion sequences, rotations with very high axial angles of rotation, short cycle times and small bending radii. ex works, but can be individually adjusted between 99 percent and 21 percent.

New process for radical and disruptive innovations

LAPP presented an initial prototype of ETHERLINE GUARD in its futureLab at the Hannover Messe 2019. This was an initial laboratory model. It was a first for LAPP to present a concept idea rather than a finished product at a trade fair.

This was based on a new innovation process, called Innovation for Future, which for the first time, also enables radical and disruptive innovations. In contrast to the classic Stage-Gate process, three prerequisites must be fulfilled at the same time: a technical solution must be developed, it must be discussed with at least one potential customer, and a business model must be developed that primarily describes the target customers. The crucial difference is the role of management. Instead of just saying yes or no to a development stage at defined intervals, managers are now called upon to contribute ideas. They build networks for the innovation team and provide the budget, which means not only money, but also freeing up time.

The Innovation for Future process gives the freedom to also drive innovations outside of the core business.

The early introduction of ETHERLINE GUARD to potential customers – the device was still called the predictive maintenance box back then – was extremely helpful for LAPP in the development process. Thanks to direct customer feedback, it was possible to prevent the innovation from being developed bypassing the market. As early as 2020, ETHERLINE GUARD was used by three pilot

customers from the medical technology, automotive and intralogistics sectors, as well as in the LAPP service and logistics centre.

Insights from pilot projects

During the pilot projects, the LAPP development team was able to gain some important new insights. The results with regard to the ageing process of Ethernet cables were particularly exciting. Contrary to the general view that a wire break in a copper conductor causes the end of the lifespan of a dynamically moving data cable, it became apparent that in most cases wear and tear and changes in the insulation layer are responsible for the deterioration in the transmission properties of data cables.

The reason for this is that the propagation speed of electromagnetic waves is not determined by the copper, but mainly by the insulation. The insulation layer is applied to the conductor in a three-stage extrusion process, in which different functional layers are generated. This high technical complexity enables a very low permittivity value to be achieved.

To put it simply, the lower the permittivity (also known as dielectric conductivity), the less interference on the electrical field of the conductor and, as a result, the higher the speed of an electromagnetic wave in a core.

For this reason, polyethylene or polypropylene with low relative permittivity values are used as insulation materials for data cables. Special processes such as foaming are also used to introduce air bubbles into the insulation material to further reduce the effective permittivity. If a data cable is now subjected to permanently high mechanical and dynamic loads, this insulation layer will change. For

example, this results in a local capacitance change, which in turn changes the local characteristic impedance of the cable. At these interference points there are undesirable reflection effects or unacceptable differences in signal propagation delay, which in turn impair the data transmission properties. These effect occurs some time before the copper wire actually breaks.

However, LAPP was also able to gain important insights regarding customer behaviour: Many mechanical engineers are rather reticent when it comes to using an IIoTcapable device with wireless connection and prefer a wired to a wireless solution. For this reason, LAPP decided to offer the two variants of ETHERLINE GUARD described, with and without a wireless module. At the same time, simple operation yet complex functionality were important to customers. The monitoring device should work intuitively, but should be as small and cost-effective as possible.

Important step on the way to the Smart Factory

ETHERLINE GUARD is particularly suitable for data cables that are exposed to constant “stress”. This includes movement at high speed and acceleration, changing motion sequences, rotations with very high axial angles of rotation, short cycle times and small bending radii. The device is also used in critical processes, where a downtime would result in high to extremely high downtime costs or even personal injury.

Power over Ethernet— supply for Ethernet devices via data lines

SOURCE: ANALOG DEVICES

Learn how Industrial Ethernet devices can use effective cabling for simultaneously transmitting data and for supplying power. Power over Ethernet (PoE) systems are widely used in the industry and will play an important role in the future. Why not use the Ethernet cable for both data transmission and supply?

Block diagram showing the main components of a PoE system.

This article describes how Ethernet devices can use the cable simultaneously for transmitting data and for supplying power.

Power over Ethernet (PoE) systems are widely used in the industry and will play an important role in the future.

PoE standards

The supply of power via a Cat-5 cable is defined in the IEEE 802.3af Power over

Ethernet standard. The PoE standards used to be limited to a few watts, but newer PoE technologies enable even higher power.

For example, PoE+ allows power up to 25 W per port and PoE++ (a four-pair Power over Ethernet system) ranges from 70 W to 100 W by using all of the wires of the existing cable. In parallel to this PoE standard, Analog Devices has defined the proprietary standard LTPoE++™, which defines the specifications up SOURCE: ANALOG DEVICES

IN PROCESS AUTOMATION SYSTEMS, IMPORTANT parameters such as temperature, pressure, flow rate, humidity, and many others must be monitored and measured. In the era of Industry 4.0, Ethernet is a popular communication standard. Because Ethernet is wired and transmitters and sensors typically require a power supply, the question arises: why not use the Ethernet cable for both data transmission and supply?

Plug and play capability, easy implementation, and a safe, robust power supply are further features of LTPoE++.

Moreover, LTPoE++ is interoperable and backward-compatible with the standard PoE specifications of the IEEE. However, the actually usable power is somewhat lower than the specified PD power because of losses in the system as well as cable losses, as is also the case with PoE+ and PoE++.

has the task of adjusting or covering the power requirements of the components supplied by the PD. Newer ICs already offer the possibility of integrating the interface and the dc-to-dc converter into a single component for low power classes, which simplifies the design.

Because PDs must accept a dc operating voltage of any polarity over their Ethernet inputs according to the IEEE 802.3 PoE specifications, two diode bridges are required in front of the inputs of the PD. Thus, the PD also works with reverse polarity, regardless of the wire pair used.

PoE components

PD implementation made easy

Essentially two components are necessary to supply devices over the Ethernet cable: the powered device and the power sourcing equipment (PSE).

The PSE has the task of delivering the power like a power supply, whereas the PD receives the power and uses it (load). PSE devices have a signature process while powering up to protect incompatible devices from damage when they are connected.

This involves first checking the signature resistance of the PD. The PD will only be supplied with power if this value is correct (25 kΩ). If the PSE detects a PD, it starts with the classification; that is, with the determination of the power requirements of the connected device.

For this, the PSE applies a defined voltage and measures the resulting current. The PD is assigned to a power class on the basis of the current level. The full voltage and current will be supplied if everything is correct. As soon as the PD is supplied, it has the task of converting the PoE voltage of –48 V to a supply voltage suitable for the terminal devices.

In typical PD designs, an additional dc-to-dc converter (diode bridge controller) is used. It

With the LT4276 from ADI, an LTPoE++-, PoE+-, and PoE-compliant PD controller with an integrated isolated switching regulator exists. It can be operated both for forward and for flyback topologies, and synchronously for power classes from 2 W to 90 W. Unlike conventional PD controllers of lower power classes, which also have integrated power MOSFETs, the LT4276 offers the option of driving an external MOSFET. Through this, the PD decreases its losses and increases its efficiency.

Because the IEEE 802.3 Ethernet specifications require electrical isolation from the ground connection of the device housing, the LTC4290/LTC4271 isolated controller chipset is suitable as a PSE. The LTC4271 represents the digital interface to the PSE host on the nonisolated side, whereas the LTC4290 offers the Ethernet interface on the isolated side.

The two components are connected by means of a simple Ethernet transmitter.

Through this robust PSE chipset design, additional components for generating the isolated power supply can be avoided.

An increase in the power and efficiency of

the overall PoE system can be achieved if the two diodes of the full-bridge rectifier on the PD side are replaced by ideal diodes. Therefore, MOSFETs are used and controlled such that they act like typical diodes.

Through this process, the forward voltage can be drastically lowered due to the low channel resistance (RDS(ON)). With the LT4321 ideal diode bridge controller in combination with the LT4295 PD controller, four MOSFETs can be controlled in a full-bridge configuration.

With PoE, Ethernet devices can be supplied with power at the same time as the actual data transmission takes place via an RJ45 cable. Analog Devices has developed its own proprietary standard, LTPoE++, that supports powers of up to 90 W in parallel to the conventional PoE standards. LTPoE++ offers a robust, end-to-end, high power PoE solution that simplifies the power supply and the design.

The new Chronous™ portfolio is ADI’s portfolio for innovative Industrial Ethernet products. It includes real-time Ethernet switches, PHYs, and protocol processing products, as well as complete network interface products.

The Chronous portfolio was recently expanded with ADI’s release of two new robust Industrial Ethernet PHYs, ADIN1300 (featuring 10 Mbps to 1 Gbps range) and ADIN1200 (featuring 10 Mbps to 100 Mbps range). By combining those new PHYs with ADI’s PoE technology, the Chronous portfolio enables best-in-class, system-level solutions for both power and data.

Secure and manageable smart network at lightning speeds New Ethernet switch technology offers cost-effective and operational efficiencies to meet expectations and simplify the burden of configuration for effective industrial networking. The switches offer four operating modes that can be selected through the mode button, dealing with different scenarios.

SOURCE: ETHERWAN

TO MEET THE NEEDS OF INDUSTRIAL FIELDS such as Process Automation, Building Automation, and Renewable Energy, EtherWAN has announced new hardened managed Ethernet switches – the SmartE series. It is designed with the most frequently used Layer 2 functions to offer precise and suitable network management features, while providing robust wired connectivity with an economic approach. The SmartE series has four operating modes that can be selected through the mode button, dealing with different scenarios.

Operating Mode 1: reset to factory default

Users can reset to the factory default when they need to solve unexpected human errors, such as: • Configuration error. (e.g. Configure VLAN by mistake, and then lose accessibility to reconnect to the switch) • Cannot access the switch, due to forgotten username or password.

Users can apply ‘Mode 1’ to delete any stored configurations on the SmartE switch.

This will reset the switch to initial factory default settings.

Operating Mode 2: Operating with a Fixed IP address

Interface Card (NIC) configuration until an approval process is completed.

Almost every laptop’s NIC default setting is ‘DHCP client’ – the user doesn’t have to change the IP configuration in Windows. Select ‘Mode 2’ on a SmartE and it automatically becomes a DCHP server, and will assign your connected laptop an IP address in the same subnet.

Therefore, without manually configuring your laptop, users can quickly access the SmartE switch via a predefined IP address directly.

NIC settings are not required.

parameters of a switch to access it, they can select ‘Mode 3’ on the SmartE. It will reset the stored IP parameters (IP address, the subnet mask and the gateway address) on the switch to its defaults. Users don’t need to worry about other configuration settings on the switch; the saved settings will remain in place.

Operating Mode 4: Operating in IP security mode

Using remote access to help manage devices onsite is convenient, but the remote work might present additional security risks. To prevent the risks, select ‘Mode 4’ to make the SmartE switch and its network environments safer to use.

Operating under this mode will disable all remote management interfaces (IP, WebGUI, CLI, and Telnet) of the switch to protect the operational network, with no worries about your configured VLANs, or network redundancy (e.g. RSTP) setting, etc., which will still be running.

Another benefit for inexperienced users to apply ‘Mode 4’ is accomplishing a plug & play redundant network environment. Users can quickly deploy switches on premises without any pre-configuration settings required, and network redundancy mechanisms are automatically enabled without any manual configuration needed.

Next-generation industrial networking solutions help provide futureproof industrial automation leveraging robust hardware, as well as high-performance and dependable networks. IEC 62443-4-1 offers security technology to unite networking and OT cybersecurity using a layered defense-in-depth approach.

The IEC 62443 series of standards cover all aspects of security requirements, offering a common language for component suppliers, system integrators and asset owners. operational applications deployed at the edge will leverage containerization by 2024.

This will enable a more open and composable architecture, which will be necessary for resilient operations. The rise in edge devices and expanded connectivity represent a pathway into operations. They are being deployed at a high rate and utilize more open architectures and capabilities compared to the isolated automation systems of the past.

These devices must have both their software and hardware elements developed securely to last throughout their product lifecycle, integrate seamlessly into the network overall, and have security management capabilities.

“Networking and cybersecurity have strong synergies in operations settings, yet they both must be purpose- built for OT environments. With the digital future and increased connectedness of operations, new industry requirements and standards will be put in place to ensure providers can keep up with these requirements,” said Jonathan

Lang, research director of IDC with a focus on Worldwide IT/OT Convergence Strategies.

“These specialized industry requirements can be overlooked by many IT cybersecurity solutions, and combining subject matter expertise and capabilities from operations is critical to ensure integrity of security systems.”

To create a foundation for futureproof operations, many system integrators require that component suppliers comply with the subsections of the IEC 62443 standard that pertain to their devices. The software development process-related IEC 62443-4-1 and the product-related IEC 62443-4-2 standards highlight the importance of selecting vendors that provide hardened hardware components built with a “secure by design” approach.
