Transmission reliability
Special illumination concept
To ensure the same transmission reliability in the bus system as in the main line, the SAI Universal PRO system uses CAN. As a result of the many applications in the market, this solution in particular is especially cost-effective and resistant to faults.
As on our standard SAI Universal modules, the Pro modules have illuminated markers to make recognition particularly easy and for relating the LEDs to the channels. Flexible assembly
There are many IO gateways available such as PROFIBUS-DP, DeviceNet, USB and the Ethernet dialects: EtherNet/IP, Modbus TCP and PROFINET IO. The gateways have 16 digital inputs and the USB module additionally has 8 outputs. The USB is connected to a USB port on a PC and works on any USB port once the relevant drivers have been installed. An implementation using the Modbus standard protocol is possible.
The transverse holes enable mounting of the Extension IO modules from the side. Elongated holes help with assembly alignment.
Extension IO modules In addition to the familiar digital input and output modules, the SAI Pro system also includes a counter module, thermo, PT100 and analogue modules. This extensive range offers all the possibilities. Special labelling concept Our modular terminals usually use marker strips. We have logically transferred this system to the SAI Active Universal and Universal Pro modules. It goes without saying that the labels can be printed using the PrintJet.

SAI Active Universal Pro
The trend from IP20 to IP67 or from switchgear cabinets to cabinet-less machines has reached a peak with IP67 I/O slaves. These plug & play solutions completely do away with connection of individual conductors. This not only saves time, errors when connecting individual wires no longer occur. IP67 bus modules are the most modern and cost-effective solution for the connection of sensors and actuators.
Weidmüller is the leading manufacturer of components for electrical data and power connection technology. The Weidmüller product portfolio ranges from terminal blocks, PCB connectors and terminals, protected components, Industrial Ethernet components and relay sockets to power supply and overvoltage protection modules suitable for all applications. Electrical installation and marking material, basic I/O components and a variety of tools round off the range. As an OEM supplier, the company sets global standards in the field of electrical connection technology.
What is a sub-bus system?

Product Overview
Machine installations nowadays use standardised bus systems. In Europe, for example, PROFIBUS-DP is mostly used and in North America, DeviceNet. The controllers provide the respective interfaces, making connection of a bus system very simple. Nevertheless, there can be isolated problems. The two most significant are: • The number of addresses is limited. With modular designs in which each slave is a true station with bus address, the total number of channels is limited. • The costs for a PROFIBUS slave are higher than those for a slave that integrates a manufacturer-specific bus. For these reasons, sub-bus systems have become established especially in large installations. Sub-bus systems enable I/O stations to supply further I/O stations via an additional line independent of the main bus. The advantage of SAI Universal Pro is that the gateways are slaves themselves and can therefore process I/O information. That means sensors and actuators can be directly connected to gateways from Weidmüller.
What do I have to consider? Stand-alone modules or sub-bus system instead Both systems are necessary and offer the optimal solution in your applications. What is important is finding the right solution for the respective application. You are then faced with the question of when which solution is optimal. The usual solution nowadays is to position a gateway directly after the controller and to wire the entire machine with the sub-bus system. The reasons for this are the transmission rates and the limited length of a sub-line. For the connecting cables between the sub-bus modules, it is important to use a cost-effective solution and not to introduce new special accessories. For connecting the sub-bus stations, Weidmüller uses M8 shielded sensor cables. This is new. Transparent connection The monitoring of each individual connection means that errors are quickly detected and eliminated. On the one hand, all I/O channels are diagnosed and, on the other, the sub-bus line is monitored at every Extension IO. This means that faulty wiring is immediately detected in the course of installation. In addition, the gateway IO passes a message to the PLC stating exactly where the error is located in the sub-bus connection.
