Hello all,
Could someone please help me with an issue I have with a Siemens S7 TS ADAPTOR V5.2 (MPI/DP to RS232)....
I am trying to communicate using Microwin Ver 4, to an S7-224, using a Simatic S7 TS ADAPTOR V5.2 plugged into my standard laptop.
Firstly I am unsure whether I should be using a "straight thru" 1to1 2to2 3to3 serial cable, or a "null-modem" serial cable (2to3 3to2 crossover etc) to connect the TS adpator rs232 port to my laptop... ???
(I have tried BOTH)
Secondly which type of comms driver should I be using from the "SET PG INTERFACE" option ?
I have tried PC ADAPTOR using AUTO, MPI and PROFIBUS flavours (with various baud rates etc )
and I have also tried PC/PPI cable - with various settings.
My TS Adaptor is switched to 19.2Kb.
I know from the offline project that the PLC comms port is address 2, set to speed 19.2Kb
I get various messages ranging from "timeout erros" thru " check the cable" and also "the port can not be opened..." - depending on what comms driver I use...
ANY advice would be gratefully accepted !
Thanks very much !
Steve
