Precondition: For communication through MPI, the
firmware version of the MI4 units must be 4.25 or
later. In addition, the ZB4-505-IF1/-IF2 interface
module (with/without potential isolation) must be
connected (see Section “Interface module”,
page 30).
The connection to a PLC with the MPI protocol is
made through the AUX PORT. The MI4 AUX PORT
supports RS 485 communication.
