For a PLC and a MOVITRAC
(communications processor, CP) which allows the transmission protocol to be freely programmed.
In the case of the SIMATIC
31.. frequency inverter to the PLC via the RS-232 interface. This communications module supports
the communications mode "transparent", i.e. the protocol to be transmitted can be freely program-
med by the user.
Transfer of parameter settings see the Siemens CP523 communications module manual.
