i can run "testAS511.exe" in the win directory with success.
So i know that my connection and my cable to the PLC is ok.
But if i use my own code:
fds.rfd = setPort(COM1,9600,69) returns OK di = New daveInterface(fds,IF1,0,20,2) returns OK Dim res As Integer = di.initAdapterreturns OK dc = New daveConnection(di,2,0,0) returns OK res = dc.connectPLC()() returns ERROR = -42
Also the NoDaveDemo.exe returns: Error [-21]: no message defined!
Any idear what is wrong?
