Cannot run multiple instances of the PLC simulator.

Attempts to run multiple instances of the PLC simulator  returns the following error.


The reason the error is returned is due to the default TCP/IP port 502 for the simulator to have been already used.  To resolve the issue,
a different TCP/IP port must be used for any additional instance of the PLC simulator.


The following steps can be used to run multiple instances of the PLC Simulator.

• Click on Start\Windows System.
• Select 'Command Prompt.

Change the path to the folder that the PLC simulator is installed.   In this example, I have copied the PLC simulator folder to my root C: drive.

Type in the following command for each instance of the simulator.

sim /IP(Ipaddress) /Port(TCP/IP port number)

i.e., C:\PLC_Simulator>sim /IP127.0.0.1 /PORT503

• Start the the Control Expert applications
• Connect to each simulator using the IP address and port number for the applicable instance of the simulator.

i.e., 127.0.0.1:503
