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
