    Anybody knows if a USB/PPI adapter can be used to communicate with a S7-200(224) to develop a Delphi SCADA.

    How?

    I´m almost sure that it´s possible with 232/PPI adapter. Am I right?

      1st: Why would you want to use 8.1 instead of latest (8.2?)
      2nd: I do not know this hardware. While PPI is supported, with the USB-PPI adapter one of these might be true:
      1.The adapter emulates a COM port. Then it should work.
      2. The adapter doesn´t emulate a COM port. It has proprietary drivers from Siemens. Then it may work via the S7online procol on windows only

        Your are right, i should use 8.2

        It doesn´t seem to be simulating a COM port but i agree with you that it may be using a Siemens driver.

        The problem is :

        - What should i do to connect trough S7Online?
        - Is S7Online installed with Micro/Win 4.0, i don´t think so.
        - Where i get s7Online?
        - Some examples of connecting with libnodave trhough S7Online.

        Thanks a lot
