CAN 400, communication module

The CAN 400 PRO module, for use in an S7-400* from Siemens, enables connection of CAN participants with the automation device.
The module can be plugged into either the central frame or the expansion frame.
It supports CAN 2.0A (11 bit) and CAN 2.0B (29 bit) telegrams with a freely selectable baud rate from 10 kbps to 1 Mbps. The CAN 400 can be operated as Layer 2, CANopen® master or CANopen® slave.
The module contains the scripts for "Power On”, "Stop -> Run”, "Run -> Stop”, "Power Off”. Using a multi-stage acceptance mask, relevant IDs can be pre-filtered for the automation device.
In the CAN 400, there are 16 freely settable timers up to a resolution of 1 ms. Each timer can trigger a freely programmable CAN telegram. This means the synchronous protocols widely available in drive and servo control are easy to implement using the CAN 400.

Note 
Information about the parameterization software CANParam and about the data handling blocks for the PLC you will find under CAN Software. When first used, data handling blocks are required for the PLC.
