Control Expert Simulator and Operator Terminal Simulator connection fails with message "PLC connection failed. Automatic return to off-line mode"
The control expert simulator seems to run fine until the operator terminal simulator is started. The control expert PLC code goes offline with message saying "PLC connection failed. Automatic return to off-line mode". The operator terminal simulator stays on communicating with the simulator. However only when it is closed, the control expert PLC code can go online with its simulator.
