Using VC++ Application to Communicate with Siemens PLC over Profibus


Thread Starter


I have developed an SDI MFC Based Application in VC++ 6.0. I also have a PLC which has Profibus Communication. I need my Application to communicate and acquire data with the PLC. How do I do this?

If you are using STEP 7 as programming software it comes with an OLE Automation Interface that install with your STEP 7. You can use that OLE server. write a client MFC Application and you can connect to the PLC no matter what protocol you are using as long as are properly configured to connect to your PLC.
