Protocol-independent integration of CAN-based devices

Wago (Germany) shows at the SPS/IPC/Drives 2012 in Nuremberg its 750-658 bus terminal for connection of CAN-based devices to the Wago-I/O-System 750.

THE TERMINAL WORKS ON THE CAN data link layer (ISO/OSI layer 2). Thus, it may be applied in CAN-based systems independent on the used higher-layer protocol e.g. CANopen, J1939, or DeviceNet. Protocol-specific functions may be realized by means of an application program. Using the automatic bit-rate detection mechanism (Auto Baud), the device adjusts itself to a bit-rate in the range from 20 kbit/s to 1 Mbit/s. It is also possible to set a fix bit-rate. The terminal supporting CAN frames with 11-bit and 29-bit CAN-IDs (identifiers) offers six programmable message filters.

The device may be applied in three operation modes. The Sniffer mode allows to analyze the CAN network traffic without interactions. In the Transparent mode, the terminal works as an active CAN participant able to send and to receive messages. The Mapped mode makes it possible to generate CAN frames directly from the process image.

It allows also to copy selected process values from the received messages into the input process image. The sending may be done cyclically, manually or event-triggered on change of a process value. The modular bus couplers and controllers of the company’s I/O system 750 (providing more than 400 modules) may be applied depending on the application.
