ComPort (Communication Port)
The ComPort parameter specifies the communication port that will be used for outputting data. When communicating over TCP/IP, use the variable returned by the TCPOpen function as the ComPort for GOESTable. If the PakBusTCPServer setting is being used rather than TCPOpen, use the Route instruction for the ComPort parameter.
