Modular control system with additional CAN interface

The robustricosTP control and I/O system from Wieland Electric now comes with an additional CAN bus coupler and thus an additional CAN interface.

The robustricosTP control and I/O system from Wieland Electric now comes with an additional CAN bus coupler and thus an additional CAN interface. This is, for example, required for connecting sub-systems to the central control system via the existing CAN bus in automation solutions for mobile applications. With only one CAN interface, it is not possible to connect additional distributed I/Os via the CAN bus, as the only CAN interface is already in use.

ThericosTP CANopen IF module now provides the user with an additional CAN interface. If it is needed, the bus coupler can simply be plugged in next to the PLC module, which then takes over the control functions. The system can be expanded with additional digital and analog inputs and outputs via the integrated CANopen For the trade press SPS/IPC/DRIVES 2010 November, 23– 25, 2010 Key word:ricosTP modular automation system with additional CAN interface module 2 Press Release: 2010-11-265 master. Connection to a higher-level system is carried out directly via the bus coupler.

This type of system is mainly used in railway technology and outdoor applications, as well as in the manufacture of large vehicles and utility vehicles. Just like thericosTP modular automation system, the interface module meets the requirements of Germanischer Lloyd (GL) Category C, and of the standard for railway applications (according to EN 50155). It is specifically designed for applications in harsh environments and a temperature range of -40 to +70°C, and provides a high interference immunity of 20 V/m (according to EN 50121).

CAN bus: The CAN bus (Controller Area Network) is an ISO-standard, realtime- capable field bus for serial data transmission in automotive, automation and production engineering applications. The CAN bus system is a 2-wire bus with open architecture for serial communication. CAN protocols are now well-established in various, mostly safety-relevant sectors, where a high degree of data integrity is essential. CANopen is a special CAN-based communication protocol which is mainly used in automation technology, in particular in embedded systems.
