[Cannot communicate with the PLC with the specified UnitID!]

Hi, this could also be a UAC / Permission issues, since the communication dll is trying to extract an xml file.

You could make the dll not extract the dll, and use it in RAM, by:

 

PLCFactory.WorkWithXmlInternally = true;

 

(Do this just once, when the application starts).

 

 

Tell me if it helps. If not, when you can debug the code (the exception you see hides the actual error. I don't know if it fails dues to timeout or some other issues).

I have this problem.

i show that my problem is a timeout. 

In this case what i do?

thanks
