Data is exchanged with the CPU via the backplane bus. The data handling blocks, which make handling CAN communication simple, are supplied with the source code for layer 2, CANopen Master and CANopen Slave communication. The scope of supply includes a Windows parameterization tool "CANparam" to simplify setting the CAN communication parameters.

The CAN 400 module supports 11-bit CAN-ID and 29-bit CAN-ID frames with a freely selectable bit-rate of 10 kbit/s to 1 Mbit/s, or freely editable bit timing.

The CAN 300 module contains the power management functions "Power On", "Stop -> Run" and "Run-> Stop". Using acceptance mask or node-filter, it is possible to prefilter the IDs relevant to the programmable controller.

15 freely settable timers are available in the CAN 400 module. Each can trigger a programmable CAN frame. In that way it is easy to implement the synchronous protocols common in drive and servo controls through the CAN 400 module.
