DEar All,
I´m trying to develope a little application (like a little Scada) inwich I have to communicate my PC with a PLC Siemens S7 300 via Visual Basic.
I understand I could use an OPC server but is out of muy budget. I read something from "DesertDog" saying it is possible to do it witho out any extra sofware.
COuld any body tell me somthing more about it?
thank you very much
