Hi
I'm working on a project that will eventually involve a PC running Citect talking to some S5 PLC's.
I've got to the stage where I want to test the project but I haven't got any S5 PLC's to test it with so thought I'd hook it up to a S7-312 that I had knocking about.
The protocols available for S7-300 series mention a CP5613 card using MPI.
I don't want to invest in a card just to run a test and wondered if there would be any way of using my programming lead from the com port of the PC to connect to the MPI port on the CPU. The programming lead has obviously got a 232 - MPI adaptor built in to it.
Does anyone know whether it is possible to set up any comms this way or am I just wasting my time. I'm not bothered about speed etc, this is just really to test that my software is transferring everything to the correct place within a Data Block etc.
I've also got a CP340 (RS 232C) card on the test rig so maybe there is an alternative way of connecting the two utilising this??
Anyone any ideas?
Cheers
JT
