Bus interface (X11/3)
9.11.1
General
You can directly connect MODBUS-panels (e.g. our PMI 315). To connect, an adapter cable is
need (see page 41). You can order a cable from us.
The PMCprimo Drive2 is equipped alternative with Profibus DP-S small. The connection is done
always by the connector X11/3. When using the option Profibus DP-S, the MODBUS is out of
service.
In Standalone mode (see PMCprimo programming manual) at every control a panel can be
connected.
In networked systems (CAN) the panel has to be connected to the host system. Only the host's
Bus-interface is active in this mode.

•
9600 Baud, 8N1, no handshake
