Precondition: For communication through CANopen,
the firmware version of the MI4 units must be 4.40 or
later. In addition, the ZB4-507-IF1 interface module
must be connected (see Section “Interface module”,
page 30).
The connection to a PLC with the CANopen protocol
is made through the AUX PORT of the MI4. The AUX
PORT supports RS 485 communications.
