It has been a while since I have used RSLinx extensively, but I do not remember ever seeing anything like this.

We have a customer whose C-more will only communicate with his ControlLogix via Ethernet (ENBT)if the PC is connected through RSLinx. If the PC is not connected, the C-more and ControlLogix do not communicate.

Here is the wierdest part. The PC can be connected either DF1 or Ethernet to the PLC and the C-more and ControlLogix will comm.
