Hi,
I need to connect to PLC (PM172) but always receive the same response: time out.
I'm using the software libraries from Ricardo Saat, but i don't know if i'm not doing good.
If i use other components (not free), the result is ok. But i can't pay them. I have to develop a component very simple, but this component has to connect every second to PLC.
Have any one any idea? Can anyone send me source code in Visual Basic or Visual C++ to connect with a PLC?
Thanks a lot.
