S7-200 PPI cable communication HELP

    Hello , I have problem with connecting a CPU222 with the nodavedemo in delphi.

    I am using the NoDaveDemo.exe in Delphi together with a CPU222 with a PPI cable(the PPI Cable is not made from Siemens) and a USB to RS232 converter.

    I configure the NoDaveDemo settings for the communications as :

    Protocol   : PPI Protocol
    Com Port   : COM2
    MPI Speed  : 19.2 kbit/s
    MPI Local  : 1
    Remote     : 2

    CPU-Rack   : 0
    Slot       : 2
    Timeout    : 100
    Interval   : 1000

    I also configure the communications settings of the CPU222 with the same
    Address

    Local   : 1
    Remote  : 2

    Network Parameters
    Interface : PC/PPIcable(COM2)
    Protocol  : PPI
    Mode      : 11bit
    HSA       : 31

    Transmition Rate
    Baud Rate :19.2 kbit/s

    I also do the same for the PC/PPI cable parameters from set PG/PC interface.

    Why can not I communicate between the NoDaveDemo and the CPU222?

    P.S

    I can download and upload a program with my PPI cable and the USB-RS232 converter throught the Micro/WIN V4.0

      Hi

      I have the same problem.  The testppi.exe works but the demo in delphi dose not.  Has the demo got a bug in it or dose it not work with PPI? Is it possable for some one to post a small programme just to connect to the s7-200 PLC so i can make sure the component is correctly installed and working.

      Thanks

      Ok
      You need to mod the NoDaveComponent.pas file and change the parity to even

      DaveFDS.rfd:=SetPort(@Address[1], Speed, 'O');
      To
      DaveFDS.rfd:=SetPort(@Address[1], Speed, 'E');

      You then need to change com speed to daveComSpeed9_6k in the Delphi object inspector.  This allows yoy to connect the demo to an S7 200.

      Hello guys , I have tried the things you told me but I still can not communicate with the CPU222 and the delphi through   PPI cable. What seems to be the problem?

      Do you think is the usb-RS232 adaptor ?
      Do you think is the PPI cable ?(because is not the official fro siemens)

      Can anybody help me understand what is wrong?

      Regards

      But the MicroWin4.0 works with the USB-RS232 converter.

      -How can I make it work also with the delphi??
      -Do I need a real RS232 card?
      -Do you know any converter that works with the delphi?

      Ohh and something else...

      -Do you thing I will have the same problems if I buy and use the "PC/PPI (PCPPI) - USB + OI Version" from siemens together with Delphi??

      Thank you very much

      Regards
