Schmersal launches new safety light grids with Bluetooth interface

The SLC440/COM with Bluetooth Low Energy (BLE) is an active optoelectronic protective device that makes all status and diagnostic data available on smartphones or tablets via a Bluetooth interface on a real-time basis. It allows the ability to save data that then could be used to document a repeat test or for predictive maintenance purposes. Until now only diagnostic tools based on NFC technology have been available on the market. While NFC tools only offer a range of a few centimetres, the Bluetooth BLE interface can achieve a range of 100 times more at up to 5 metres.

Electric car makers have long been clamoring for a battery breakthrough that will improve the range of their vehicles while also extending their lifespans. Innolith, a Swiss startup, says its new high-density lithium-ion batteries can do just that. The company claims to have made the world’s first 1,000 Wh/kg rechargeable battery. By comparison, the batteries that Tesla uses in its Model 3, the so-called 2170 cells are an estimated 250 Wh/kg. If Innolith’s claims turn out to be true, its high-density battery may have just leap-frogged over anything in production. A battery with that density would be capable of powering an electric car for 1,000 kilometers on a single charge. That’s far greater than the current lithium-ion batteries on the market today.

Conventional lithium-ion batteries used in electric vehicles today use organic electrolyte, but Innolith uses inorganic electrolytes which is non-flammable - eliminating the main cause of battery fires that plague electric vehicles.

NASA says space causes genetic change

04

For 340 days, NASA astronaut Scott Kelly lived and worked inside the International Space Station while his identical twin brother Mark, stayed on Earth. In comparison to his brother a year in space caused Scott’s carotid artery to thicken, DNA damage, gene expression changes, a thickening of the retina, shifts in gut microbes, reduced cognitive abilities and a structural change at the ends of chromosomes called telomeres. But it did not alter or mutate his DNA. Other differences included the shape of Scott’s eyeball, including a thickened retinal nerve, while the skin on his forehead became thicker. A series of tests also showed Scott’s cognitive abilities declined.

This robot by Stanley parks your cars

French startup Stanley Robotics has come up with a new way to park your car, through an electric-powered and autonomous robot called ‘Stan’. Stan debuted in a 500 space parking lot located at a French airport in Lyon. A total of four Stans will be taking the cars to the parking spots and bringing them back. The company has stated that in a standard parking lot, Stan is capable of creating 50% more parking space because of its capability of parking cars more efficiently.

The company has also stated that Stan can reduce the carbon dioxide emissions by taking out the passenger vehicle traffic at parking lots.

If successful Stan will be expanding to looking after 6,000 parking spots at the airport.

The next generation of MDT Autosave

MDT AutoSave v7.0 includes the release of the much anticipated AutoSave Portal. It’s a decision support dashboard enabling users to view all AutoSave activity. This includes program activity, success/failure of device program results, program comparison details and much more. This vital information is accessed from a single web interface that can run on workstations, laptops and mobile devices.

World’s most advanced camera

A team of physicists and astronomers have created the world’s most advanced camera called Darkness. The suitcase-sized device is not created for taking images but for spotting planets around the nearby stars and look for alien life. It is not easy for the Earth-based laboratories to look for exoplanets since the light from celestial objects becomes distorted as it passes through the Earth’s atmosphere and when it reaches us from K12A world’s longest electric bus exoplanets it is completely faint.

Chinese bus manufacturer BYD has announced its K12A - the world’s first 27-metre ‘pure electric’ bus - at the Redundancy revolution company’s headquarters in Shenzhen. With a passenger capacity of 250 people, it is the longest fully electric bus in With the CP series, PULS now offers a unique feature: Power the world (previously at 24m) and can travel at a maximum supplies with an integrated decoupling function. Based on speed of 70km/h, it’s claimed.

New bot destined for warehouses Boston Dynamics is at it again, and their latest trick is a “reimagining” an older robot known as Handle.

Turns out it’s great at stacking boxes. Handle autonomously performs mixed SKU pallet building and depalletising after initialisation and localising against the pallets. The onboard vision system on Handle tracks the marked pallets for navigation and finds individual boxes for grasping and placing, meaning that the robot can see the boxes before picking them up and putting them down, and keeps records of what it does.

Smart glove promises connected touch for Industry 4.0 German engineers have developed a new smart glove that communicates the position of the user’s hands, a feature that has potential for Industry 4.0 applications. The technology, which will be on display at Hannover Messe, is the work of researchers from Saarland University in Saarbrücken. It integrates a glove with an ultra-lightweight, flexible film made from an elastic polymer. An electrically conducting material is printed onto both sides of the silicone film. When a voltage is applied, the resulting electrostatic attractive forces cause the film to compress, extending the film laterally and increasing its surface area. This, in turn, alters the electrical capacitance of the film, effectively transforming the film into a sensing device.

Measuring the resistance of the film and using algorithms to process the motion sequences, they could calculate the position of the wearer’s hand and exactly how it was moving.

Blue the robot is a blueprint for future bots Blue, a new robot from UC Berkeley will not only be safe to work alongside it, but also cheap to produce. it’s made from bulky, 3D-printed parts, and it has a pair of humanoid robot arms with pincers for hands.

It can be controlled using VR handsets, which let operators wave their arms about and then Blue will wave its arms in tandem. It can also be trained to manipulate objects using artificial intelligence, a control method that’s still surprisingly rare in robots. It has a central vision module with a depth-sensing camera, and its arms are controlled by motors with rubber bands that give it flexibility. If you push against an industrial robot arm, it’s like pushing against a brick wall. But Blue is more like a human in a crowded subway car: jostle it, and it’ll move aside. This makes Blue safer to work around but also suitable for research using reinforcement learning.

A shift PLCs, historians and SCADA systems historically provide the onsite solution to view the mining production process from an operational standpoint. It is somewhat isolated from the IT business systems that control the orders, forecasting and planning. This separation in company visibility puts a hold on moving towards next generational growth. A major global miner with multiple iron ore mines in one Australian region moved its short-term production, planning and control activities from the mine sites to its new remote operations centre.

data to t e k r a m utilises l o r t sed to n u o s C i d n e o i s i t Optim predic “Outcome control where the n error occurs.” rd re a feedforwa the process befo o respond t

Value chain Thankfully major PLC manufacturers like Emerson are embedding the IT connectivity within the PLC control layer device to make industrial 4.0 interactions seamless. The Emerson CPL410 PLC comes with Open Linux Ubuntu embedded into the PLC to become an Optimising Outcome Controller (OOC). Its operating system is half open Linux with SQL, Python, Apache Web server and half Programmable Automation Controller (PAC) sitting on top of a hypervisor hardware platform.

Optimised control The benefits of linking the value chain between OT and IT in the heart of the manufacturing process is transparent and return on investment is quick to realise. Evolution Mining introduced a live online data monitoring system to the Mungari mine which improved the average payload of trucks by 4% in the commissioning phase.

Traditional PLC’s are feedback control; the system waits for an error to occur between the measured value and the setpoint before responding, making the system reactionary. Outcome Optimised Control utilises market data to feedforward control where the prediction is used to respond to the process before an error occurs.

Delving deeper into the analogy of PLC control, proportional integral derivative (PID) loops are used to set flow rates, temperatures, tank volumes, pressures and the like. Typically set according to the confined process using static setpoints regardless of the influence from outer process systems or environmental conditions. These PID loops must be fine-tuned periodically to get the best output from the machine over time. However, by linking the PLC control layer to the external business systems using OOC, it is now possible to automatically tune PID loops with high precision using techniques in the outer business system loop according to demand, or weather conditions to analyse process dynamics to determine optimal gains automatically.

“IT Systems now have direct access to the control layer, and the control layer can leverage IT advancements...”

Direct access The ability to pass control and market data in both directions are two-fold. IT systems now have direct access to the control layer, and the control layer can leverage IT advancements so that resources companies can turn their data into actionable insights and operational improvements. Businesses can not only reduce the initial time of setting up a PID control loop, but it also allows them to dynamically adjust the loop according to changing variables and operational circumstances to increase their time to market and making their processes run more efficiently over time.

Outcome Optimised Controllers such as the Emerson CPL410 facilitate the integration of a wide range of different devices and equipment with business automation tools using standard communication protocols, making it possible to achieve a new level of business automation. It removes the complexities away from IT systems trying to communicate to non-IT automation devices by providing an IT interface on the automation controller.

Integrating the IT, OT and Cloud infrastructure directly at the control system, flattens the architecture and enables new levels of efficiencies through continually developed external cloud technologies in the IT space. Automation data now has access to predictive analytics that yields “real-life” responses according to the results of these analytics. Ideal for the digital twin concept or when consolidating data from siloed databases such as dispatch, historians and ERP solutions to agnostic cloud platforms with analytics.

Mine of the future Resolute Mining is planning for its Syama Gold Mine in Mali Africa to be an example of an Underground Mine of the Future. It aims to establish fully automated loading and hauling, automated fleet and production management and scheduling, real-time tracking, monitoring and data analytics with the rollout of driverless trucks, loaders and drills in 2019. It is expected to lead to improved safety, higher productivity and lower operating costs through industrial 4.0 connected fleet management. Local SCADA systems usually provide alerts for alarms and events but can be quite challenging to debug and diagnose the issue in the field especially in remote areas. OOC makes it possible to use Edge technology to monitor and diagnose a fleet of control systems remotely and securely using cloud-based services. It ensures complete accountability for various remote assets and provides a real-time assessment of the health of their systems.

Integrating augmented reality into the production process, operators can identify heavy vehicle, and machinery health statistics live from their database reducing time and data mishandling. Manual paper forms are a thing of the past; service logs and fuel reports are electronically gathered. The Outcome Optimised Controller utilises the onboard Linux programming environment to provide the necessary platform and processing power to integrate sensor data stored in the SQL database sent to the augmented reality glasses HID. When the operator looks at machinery that matches a predefined shape or AR marker, the data appears in the glasses for immediate decision making.

Data management Accessing internet data securely from the control layer allows the mines to use the large water pumps efficiently. By actively monitoring weather forecasts and the remaining amount of allocated solar energy versus the energy price, pump operation can be managed to reduce energy costs during the non-daylight hours, all from their smartphone, saving them up to $11,000 a month.

Where to next?

In today’s technologically driven world, businesses cannot afford to miss any opportunity to automate industrial processes and integrate onsite industrial control systems with dynamic business objectives and target outcomes.

Whether it’s building a “digital mine nerve centre” for datadriven planning, control and decision-making, or integrating cloud analytics and smart app services on board the control layer to deliver advanced technologies. Outcome Optimising Controllers offer generational advancement over traditional isolated PLC’s to provide businesses with a way to increase connectivity and information-sharing across their IT, OT and cloud-based systems. Amalgamating this technology together as one will produce endless possibilities in operational efficacy.

choices For those of you who work alongside conveyors and machinery, the emergency-stop attachment would be a good choice. It can be used as a pull-wire emergency stop including an auto shut-off feature to Performance Level PL e, plus wire breakage detection on material handling plants up to 100 metres in both directions. It really does prove to be extremely versatile…

If actuated, the two-sided pull-wire emergency stop switches latch in the emergency-stop position, and unlock when the release button is actuated.

Electrically, the connectivity options allow for a combination of two or three open or closed contacts for both actuation directions providing a total of up to 6 contacts. If desired, a high-level communication bus such as Dupline or AS-I-Safety-at-work for quick and easy networking, series switching and transfer of diagnostics data.

what’s inside By simply removing four screws from its yellow lid will allow access to its inner workings. You’ll see that it’s a well-protected device, with all HDS products featuring a closed cover over the switching shafts, cams and switch contacts to prevent contamination from dust and dirt when installed in extreme conditions. Wiring in the switch elements are routed to a central ‘Cage Clamp’ connecting terminal for easy and quick installation.

Lycra enthuisiast and outdoor adventurer David Kirk, chats with us on the evolution of mining and technology.

Welcome Dave - Since you’re based in WA, let’s talk Mining. We’ve seen a dip in previous years, but now there’s a large surge - why do you think that is?

Lithium has created a little niche. The world we live in is turning digital and electric - if not already - and demand will be huge. Technology is continuing to evolve rapidly, and as a result is strengthening the industry.

Do you think mining is quick to adapt to new technologies when compared to other industries?

Absolutely, mining is 100% a leader of utilising technology to maximise operational productivity and efficiencies. Innovation is at the heart of mining automation, and Australia is leading the charge.

What kind of technologies is proving popular with your clients?

The relay contacts are either selectable needed to be connected, which we as slow or snap action, which means found to save a lot of time in both pull-wire emergency stop switches or belt assembly and connection. alignment switches (amongst others) can be easily and efficiently connected, that Perhaps the most important point includes an indicator lamp (if required). to note here, is that users are able to adjust the pre-set contact switching You can choose safe or standard twopoints of the basic switches between wire bus systems such as Dupline that 10º and 35º at 1 degree increments. also can be used for signal evaluation This is extremely easy to do, by simply as an option. In our testing, only positioning the dial on the switching the input and output signal wires element into the desired end position.

The Internet of Things (IoT) has positively changed the industry, making data, communications and analytics invaluable to organisations. For my clients, I aim to help and add value through engineered solutions with access to our innovative products such as Hirschmann, Red Lion, Emerson (GE) and Tosibox.

Dave, does technology play a role for you outside of work? Are you a smart tech user?

I think most people are without realising. I have a smartphone, smart TV and smart watch that helps track my sporting activities. In my next house, I hope to set up smart technology such as lighting and music, although I do have some nifty gadgets currently at home and in my vehicle that seem to impress.

What are you passionate about?

Schmersal have designed an all-in-one switch solution for many applications.

It’s easy to customise with simple swap and connect levers, it’s easy to install, and it’s more versatile than others in the market. They have really thought about how people will use this product. For manual users, the lever positioning configuration makes the HDS design flexible enough to customise the switch or any given machinery scenario. It can be used in hazardous type environments with IP66 and IP67 protection ratings and a range of international approvals including CE, UL, CCC, EAC, Ex, IECEx and INMETRO which really solidifies its robust build and reliability Schmersal is known for.

My biggest passion is cycling and four-wheel driving.

Nothing beats a camping escape for a weekend in the outdoors, whether in the bush or on the beach.

Tell me something we may not have known about you.

In 2017 I drove over 35,000kms within WA to explore our wonderful state. The highlight was a helicopter ride over the Mitchell Falls on the Mitchell Plateau whilst venturing on the Gib River Road. I highly recommend a visit to the magical Lake Argile.

We have another adventurer in our midst Thanks so much for your time Dave.

B g to the c ’s earliest on, leadin ti a rt the world o p s n rm of tra primary fo Almost every tunnel is a solution to a specific challenge or problem. In many cases, that challenge is an obstacle that a roadway or railway must bypass. They might be bodies of water, mountains or other transportation routes. Even cities, with little open space available for new construction, can be an obstacle that engineers must tunnel beneath to avoid.

B

Sometimes, tunnels offer a safer solution than other structures.

Using the Seikan Tunnel in Japan as an example, it was built because ferries crossing the Tsugaru Strait often encountered dangerous waters and weather conditions. After a typhoon sank five ferryboats in 1954, the Japanese government considered a variety of solutions. They decided that any bridge safe enough to withstand the severe conditions would be too difficult to build. Finally, they proposed a railway tunnel running almost 250 metres below the sea surface. Ten years later, construction began, and in 1988, the Seikan Tunnel officially opened.

How a tunnel is built depends heavily on the material through which it must pass. Tunnelling through soft ground, for instance, requires very different techniques than tunneling through hard rock or soft rock, such as shale, chalk or sandstone.

Blasting in soft, firm rock such as shale or limestone is difficult to control. Instead, engineers use tunnel-boring machines (TBMs), or moles, to create the tunnel. TBMs are enormous, multimillion-dollar pieces of equipment with a circular plate on one end. The circular plate is covered with disk cutters -- chisel-shaped cutting teeth, steel disks or a combination of the two. As the circular plate slowly rotates, the disk cutters slice into the rock, which falls through spaces in the cutting head onto a conveyor system. The conveyor system carries the muck to the rear of the machine. Hydraulic cylinders attached to the spine of the TBM propel it forward a few feet at a time.

Then workers pump grout into the holes and attach bolts to hold everything in place until the permanent lining can be installed. The TBM accomplishes this with a massive erector arm that raises segments of the tunnel lining into place.

Tunnelling underwater, the most challenging of all environments and demands a unique approach that would be impossible or impractical to implement above ground. Tunnels built across the bottoms of rivers, bays and other bodies of water use the cut-and-cover method, which involves immersing a tube in a trench and covering it with material to keep the tube in place

The Future of Tunnelling As their tools improve, engineers continue to build longer and bigger tunnels. Recently, advanced imaging technology has been available to scan the inside of the earth by computing how sound waves travel through the ground. This new tool provides an accurate snapshot of a tunnel’s potential environment, showing rock and soil types, as well as geologic anomalies such as faults and fissures. While such technology promises to improve tunnel planning, other advances will expedite excavation and ground support. The next generation of tunnel-boring machines will be able to cut 1,600 tons of muck per hour. Engineers are also experimenting with other rock-cutting methods that take advantage of high-pressure water jets, lasers or ultrasonics. And chemical engineers are working on new types of concrete that harden faster because they use resins and other polymers instead of cement.

With new technologies and techniques, tunnels that seemed impossible even 10 years ago suddenly seem doable.

DEFINITION

Zone 0

A place in which an explosion atmosphere is continually present

Zone 1

A place in which an explosive atmosphere is likely to occur in normal operation

Zone 2

A place in which an explosive atmosphere is not likely to occur in normal operation, but may occur for short periods

| FEATURE

Hazardous zones Hazardous Zones are a method of identifying the potential risk based solely on the presence of the flammable substance (vapours, gases, dust, etc) under normal conditions. The higher the likelihood of the device being used when a flammable substance is present, the higher the risk, and conversely the lower the zone rating. Equipment intended for use within a hazardous zone must meet the required test standards for that Zone. These zones are determined by a set of standards, that also determine the requirements for which devices can be installed in which zone.

While each country has its own standards of conformance relating to Hazardous area Certification, the major standards and classification systems can loosely be combined as those relating to conformance standards based out of Europe, the US & Canada and the IECEx conformance initiative, which is the first attempt at reaching a globally harmonised standard.

The IECEx scheme 2

3

The IECEx Scheme is an international Conformity Assessment Scheme covering Electrical Equipment for Explosive Atmospheres, as the internationally accepted means of demonstrating conformity with IEC Standards. The objective of the IECEx System is to facilitate a single set of standards to allow international trade of equipment and services for use in explosive atmospheres, while maintaining the required level of safety. The benefits of the scheme are obvious – shorter certification lead-times, and the opening of new markets with no (or very little) need for additional testing and assessment to satisfy national standards. It is limited specifically to electrical equipment only. Unfortunately, while many countries ‘accept’ IECEx, they have not harmonised their own national standards in line with IECEx in the same way,

meaning the actual worldwide acceptance of IECEx is not as close as it may seem to be. As most of the world’s certified equipment is manufactured in Europe and the USA, the national standards of these countries are a manufacturers first choice for certification, although dual certifying devices to ATEX (USA) and IECEx, especially for Zone 1 approvals, is the norm in most instances.

Australian standards The Australian standard AS/NZS 60079 is harmonized with IEC 60079, so that the national certificate of conformity (ANZEx) is accordingly fully harmonised with the international certificate of conformity (IECEx).

Equipment certified to IECEx can therefore be used almost without exception in Australia without the need for further testing or hazardous area approvals.

conveyordss standar e updat

machine safety Aram Dehghani

O

For all applications

ur interaction with machinery is constantly evolving owing to rapid advancement in technology and business processes.

As a result the safety standards for machinery need to be continuously reviewed and updated. The once current AS17552000 “Conveyors’ Safety Requirements” has recently been replaced by a series of new standards due to some oversight for the way that conveyors are used.

The AS1755 when it was introduced, specified broadly the minimum safety requirements for the design, installation and guarding of conveyors. While it attempted to cover all the conveyors, it didn’t address the specific differences of conveyors used in diverse environments for different purposes. These days conveyors are utilised in a wide range of applications from carrying light loads over short distances (such as in pharmaceutical industries) to large conveyors transporting tons of materials over many kilometers (such as in mining and heavy industries).

The new conveyor standards, which fall under the AS4024.3 series of standards, are tailored in a way to address the diversity of conveyor applications and get into details of the technological requirements according to the type of the conveyor. They deal with the wide variation in design and operating environment for the conveyors which requires a wide range of the safety strategies to control the specific risks for the specific conveyors.

The new standards supersedes the requirements in AS1755-2000 •

AS/NZS 4024.3610, General requirements;

•

AS/NZS 4024.3611, Belt conveyors for bulk material;

•

AS/NZS 4024.3612, Chain conveyor and unit handling;

•

AS/NZS 4024.3614, Mobile and transportable conveyors.

The new AS/NZS 4024.3610 provides general requirements applicable to all the conveyor systems and shall be used in conjunction with other standards of this series according to the type of conveyor used. For example for a bulk material handling conveyor the design, installation, commissioning and maintenance of the conveyor system have to comply with both the AS4024.3610 and AS4024.3611.

expensive

A

ustralians spend nearly $11 billion a year on sport and physical activity participation fees, according to the Australian Sports Commission.

Not surprisingly, many people believe these costs are becoming far too expensive.

Experts are warning of a “growing grassroots divide between families able to afford junior sport� and those who cannot.

20

A recent study highlighted the impact sports participation fees are having on families in one state — New South Wales. In this survey of 696 people, results showed that respondents were paying over $1,100 on average to play a sport each season. On top of this, they were spending $450 on transport, bringing the total sport participation cost to about $1,500 per person per season.

According to research from the Australian Sports Commission and AusPlay released in 2018, swimming was the most popular organised physical activity for Aussies kids. The ever-popular football (or soccer) was a distant second, with AFL being third on the list.

However data from this study indicates that participation costs are rising across the board in a variety of sports. The biggest expense for respondents in the survey was registration fees levied by sporting organisations. This amounted to $225 a year on average. But many reported additional costs on things like equipment (required to play many sports), coaching and lessons, and uniforms and footwear. Each of these categories cost participants over $200 a year on average.

CLN | ISSUE 15 | JUL-SEP ‘19 The 5 most expensive sports based on this survey per person, per season including relevant fees and equipment were golf ($1,641), swimming ($1,559), tennis ($1,381), cricket ($1,142) and bowls ($930). The cheapest were rugby league ($342) and netball ($435).

Since the Government introduced its Active Kids program, allowing families to apply for a $100 voucher each year in NSW, $150 in QLD, $200 in NT, $150 in WA and just $50 in SA, to offset sports fees for their children, many believe clubs have intentionally increased their fees.

However others have said costs have been rising for years anyway and government subsidies aren’t trickling down to many families or local sport clubs.

The impact of rising participation costs is being felt in a number of ways. This study outlined that about 10 per cent of respondents had borrowed money (not including credit cards) to participate in sports at an average of $5,000 per person.

Some 35 per cent of respondents also reported greater credit card debt due to sport fees.

Nationally, sport participation rates increased slightly for school-aged children (15 years and under) outside school, from 20 per cent in 2016 to 25 per cent in 2017 according to AusPlay data released by the Australian Sports Commission.

But, again, income levels were a major factor when it came to participation rates. According to the AusPlay data, highincome families are far more likely to have children in sport programs (84 per cent) compared to low-income families (58 per cent). AusPlay data also showed a slight decrease of 4 per cent in adult participation in the 16 main organised sports across Australia from 2016-17.

induscthrieasl swit T

here are many different challenges in an industrial environment that standard commercial switches are not able to solve. Industrial Ethernet switches are designed for the harsh conditions and environments that are generally present in control networks, such as dust, dirt, vibrations, sweltering heat and freezing cold. Industrial switches don’t have the advantage of clean air-conditioned rooms and must be designed to operate in these extreme conditions.

What’s the difference?

In terms of functionality today, there is very little difference between an industrial switch and a commercial switch. Both are designed to pass IP traffic and provide a backbone for communication between the devices connected to them. There are two main areas where Industrial Switches differ, and these are:

• •

Type/availability of data Switch environment

Industrial networks have different priorities when compared to a commercial network, which means that industrial switches need to be more robust, not just to the environment, but also when it comes to the transmitting data. An industrial network must prioritise the delivery of data to ensure that the control network, for example a mine or factory, is able to operate safely and to minimise any downtime. This is achieved by using ring topologies such as MRP or RSTP to create a redundant network which can recover in as little as 50ms if there is a switch failure, or a cable is cut. There is no margin of error when even a short downtime can calculate to a milliondollar loss.

Industrial networks have much longer cycles than commercial networks, and therefore many legacy devices and protocols must be integrated into modern control networks. Managed industrial switches will often support fieldbus protocols such as Modbus or Ethernet/IP as the devices that are connected use these to communicate. Some switches will even have integrated serial ports that provided much needed support for this legacy equipment.

22

DC powered Another unique feature of an industrial switch is the fact that often, on site there will not be mains voltage, and the devices are powered via DC. A typical Industrial switch will operate between 12 – 48VDC, which can vary across the site meaning that Industrial devices must have a wide input range to cater for multiple power requirements. Industrial Ethernet switches also often have redundant power inputs. This allows the weakest link (the power supply) to have a redundancy via a backup power supply, ensuring maximum up time.

product brief RACKMOUNT SWITCH GRS Series Hirschmann™ GRS Gigabit Ethernet switches have been designed for use in harsh industrial environments with a need for cost-effective, entry-level devices. As network needs change, the switches offer flexibility through field exchangeable port modules.

They also feature a rugged design to handle demanding industrial applications, including power generation and distribution operations, like substations.

MANAGED SWITCH Bobcat Series The Hirschmann BOBCAT Switch is the first of its kind to enable real-time communication using TSN. To effectively support the increasing real-time communication requirements in industrial settings, a strong Ethernet network backbone is essential. These compact managed switches allow for expanded bandwidth capabilities by adjusting your SFPs from 1 to 2.5 Gigabit

1800 557 705 or email sales@controllogic.com.au

IP67 SWITCH Octopus Series The Hirschmann IP67/54 switches from the OCTOPUS family allow fail-safe networks to be installed in a variety of different application scenarios even under the most difficult conditions. It covers the full range of automation solutions, and is characterised by a waterproof and dust-resistant housing including an extended temperature range from -40°C to +70°C.

UNMANAGED SWITCH Spider Series The unmanaged switches from Hirschmann are a cost-effective way of entering the world of Industrial Ethernet technology without compromising on quality and reliability. All switches have been specially designed for use in harsh environments and come with all the necessary certifications. They are suitable for all applications in which switch management is unnecessary.

Hazardous environments Communication is required in some extremely harsh environments, such as a dirty, dusty underground mine, or a blistering hot open cut mine. An industrial switch must be able to not only withstand heat and dust, but do so without any moving parts, such as venting fans which reduce the MTBF of the device. MTBF (Mean Time Between Failures) is used to calculate the expected lifetime of a device.

Industrial switches are built using components that can withstand temperatures ranging from -40 to +85˚C and are designed to last a lot longer than commercial switches, usually with MTBF figures calculated well over 10+ years.

“An industrial network must prioritise the delivery of data to ensure that the control network is able to operate safely and to minimise any downtime”

IP67 Switches: Hirschmann Octopus

Many industrial sites have very specific standards that need to be met with relation to vibration, or dust and water protection.

Many Industrial devices are tested and can operate in very high vibration environments, which is achieved by not using moving parts and having special locking connectors for cables, such as an M12 connector. IP rating is also important with some devices designed to withstand not only dust but also water. A device such as Hirschmann’s Octopus is rated at IP67, meaning a complete protection from dust and protection from full immersion in water for 30 mins. Some devices are also designed for marine use, to protect against rust and high humidity.

Although there are many factors that separate Industrial switches from commercial switches, the reality is that as things like IOT and Industry 4.0 become more popular and more industrial networks are connected to the internet, Industrial switches and commercial switches are coming closer in terms of software, management and cybersecurity, while continuing to differentiate themselves to meet the requirements of their environment.

orocco is a multifaceted destination, with exciting cities, wonderful coast, the Atlas Mountains and last, but certainly not least, the Sahara Desert. Desert tourism is blooming like deserts in spring, with even more destinations, itineraries and activities available from tour operators.

As big as the USA, the Sahara stretches from the Red Sea in the east and the Mediterranean in the north all the way to Morocco and the Atlantic Ocean on Africa’s western shore. Most of the Sahara is comprised of rocky, stone plateaus, but in Morocco it becomes the archetypal desert of popular imagining, ditching the rocks for a rippling coat of towering dunes, which constantly change shape and colour, from brilliant orange to rosy pink.

“There can be a difference of 20ºC in the desert between night and day.”

Travelling to the Sahara demands a road journey of several hours, but the scenery along the way entertains as you draw ever closer to the desert. Hop out and explore remote Kasbahs and valleys lush with date palms, fields where goats nibble wildflowers and orchards of hazel and almond trees. Once in the Moroccan Sahara, you’ll find small oases fringed with date palms nestling amid the dunes, and a handful of hardy Berber people here, too, carving out a slow-paced, low-impact life that has barely changed in centuries.

Where to go Morocco has two major Saharan dune systems – or ergs, as these vast seas of shifting, windswept crests and valleys are correctly called. Erg Chebbi is located at the end of a sealed road near Merzouga, just 20km from the Algerian border.

It stretches 50km from north to south, with iconic dunes that tower up to 150m high. Erg Chegaga, 50km west of M’Hamid, is less easy to access than Erg Chebbi – you’ll need a camel or 4x4 to get amongst it – but many feel taking time to travel here is worth the effort for the silence and undiluted drama.

24

Few trips run into the disputed Western Sahara region of Morocco in the south, but it is possible to visit on an organised tour, although this will take you well off the tourist trail and away from any major cities. This is a wild, arid land of Saharawi nomads, rolling dunes and camel trains, strong traditions and awe-inspiring scenery.

CLN | ISSUE 15 | JUL-SEP ‘19

| TRAVEL

Take a tour

Trips bound for Erg Chegaga tend to go from Ouarzazate, along the lush Draa Valley to Zagora and finally to M’Hamid, at the end of the road and the start of the desert – a distance of 260km. The distances, remoteness and, often, the need for a 4x4 mean that joining a small group or tailor made trip is the easiest way to visit the Moroccan Sahara. In addition, an organised tour will arrange for a night or two camping in the desert, with a cook and crew to set up camp and usually contacts among the local Berber community. Here, you will have the chance to learn about their lives around the campfire after admiring the sparkling night sky and enjoying a hearty dinner.

Few people come just for the desert, though. Instead, multi-layered and diverse Morocco offers a host of other attractions, from coast to city and mountains. A week is enough to see Marrakech, take a short trek in the High Atlas then follow the N9 road down to M’Hamid for the desert dunes of Erg Chegaga. Or take two weeks and loop round from Casablanca to the capital, taking in old town medinas, marvellous mountains and the wide-open desert, too. Road transport tends to be the main means of getting around, although some itineraries use trains for a few sections.

Spend the night If you’ve gone to the trouble of reaching the Moroccan Sahara, it’s really worth spending a night here too. Camping in the desert is a unique experience; a chance to admire the sunset, feel the temperature drop and sleep in the complete silence of the desert. Camps can be fixed or temporary and are often quite basic, so don’t expect flushing toilets and hot running water, but you’re here for the remote, magical desert landscape and, if you’re lucky, singing, dancing and tales of traditional life from your Berber hosts around the campfire.

Spot the stars Another reason to spend the night in the Moroccan Sahara is for the stargazing. Undimmed by light pollution, the night sky over the desert is studded with stars so bright they look as though they’ve been polished.

The moon, too, is a luminous spotlight on the Saharan landscape, gilding the dunes with silvery light. Not to be missed.

Enjoy a homestay A stay with a Berber family is an incredibly special way to get to know the Moroccan Sahara through the people who have lived here for centuries. Discover how they live, and how to cook flatbread, and help draw water from the well. It’s a chance to experience authentic day-to-day life here, while also placing some useful revenue directly into a local family’s hands, providing a sustainable future for them.

DESERT EXTREMES As you might expect from a desert, it can get pretty warm here. In fact, from June to September, the Moroccan Sahara can be uncomfortably hot, so if you want to explore it properly, the best time to visit is outside these months. April and May are great times to come.

Be aware of the temperature fluctuations, though. There can be a difference of 20°C in the desert between night and day. During the cold winter months, from November to March, bring warm clothes and consider packing your own sleeping bag if you’re camping for extra warmth and comfort, even though camps supply blankets.

Ride a camel From a sunrise ride to channel your inner Lawrence of Arabia, to an extended trek with local nomads, riding a camel is rarely off the itinerary of any trip to the Moroccan Sahara. These notoriously grumpy creatures don’t offer a comfy ride, but the views are great from up on high and who doesn’t want a photo of themselves atop a dromedary to hang in their downstairs loo?

Longer treks of four or so days give an authentic insight into the nomadic lifestyle, too, and are a really peaceful way to experience the desert (and you can always lead your camel when riding becomes too uncomfortable!). Witness the varied ecosystems, not from a 4x4 but from the original land cruiser, travelling with local nomads, sipping mint tea prepared by shepherds, helping to cook bread and collect water, feeding animals and sleeping under the stars.

ABB ACS880-37-07 70A 690V variable speed drives

Project Scope Since commencing commercial production in 2013, the mine reported issues with three large existing medium voltage variable speed drives running dewatering pumps. The mining engineers reported numerous issues associated with running these high-powered dewatering pumps from an unreliable supply network.

These included power spikes, high power usage, power quality, earth leakage and nuisance trips, meaning the mine had to rethink the use of old VSD technology.

Assistance was sought to replace these drives with low harmonic variable speed drives to coincide with the next mine shutdown.

Results

Benefits The new VSD technology offers immunity to network disturbances and means a very stable output voltage in all motor load conditions, even during weak supply networks when the supply voltage fluctuates. The low harmonic input stage ensures the supply network power factor remains at unity and the total harmonic current distortion is less than 3%. The results are a considerable improvement over the 30% to 40% THDi from conventional VSD’s.

ABB ACS8 8 cabine 0-37 t build

Moreover, ABB drive’s voltage boost capability stabilises the output voltage which is a unique advantage compared to alternative low harmonic solutions where the voltage cannot be boosted. With a higher motor voltage, the same power is achieved with less current, which improves motor efficiency and no nuisance tripping previously experienced by the mine.

This solution provides superior motor driving technology that uses every watt of power efficiently to keep the total cost of ownership low and ensures the maximum motor performance for the dewatering pumps, saving thousands of dollars in power, and reliability.

TECH-TIP |

creating user- defined function blocks

by Jack Nally

O

ne of the most useful features of PLC programming is the ability to create user defined function blocks, which allow the user to break down code into meaningful chunks, making the program simpler and easier to follow. This Tech Tip will show you how to create user-defined function blocks in Panasonic’s PLC programming software FPWIN Pro.

STEP O

NE

create a new function block

STEP THREE

In the project window, rightclick POUs and click New POU. Select “Function Block (FB)”, choose the desired language and give the block a meaningful name.

insert the function block into the main program In the main program, open the instructions pane on the right side of the screen.

If it is not there, go to Window > Panes > Instructions to open it.

Enter the name of the function block, in this case “C_to_F” into the search bar and click drag it into a rung.

create variables create the code for the function block

STEP FOUR

STEP TWO

This example shows a function block that converts temperatures in ℃ to ℉.

Be sure to change the class of any variables that are going to be inputs or outputs to either VAR_INPUT or VAR_ OUTPUT. This will make them appear as legs on the actual function block in the main program.

30

The last step is to populate the input and output variables.

Simply click the question marks and enter some names.

Compile the program, enter online mode and click.

Click the Input variable, enter a value and the output variable will automatically update.

And we are done! Now that you have this function block, you can easily drop it in as many times as you like.

Good Luck!
