MPI Address... Command (PLC Menu)
Select the menu command PLC > MPI Address... to modify the network node address for the simulated PLC. The new address is stored with the configuration of the simulated PLC when you use the Save PLC or Save PLC As... menu commands.
Ensure that the node address for the offline program matches the node address for the program in the simulated PLC.
When the Simulation On/Off button on the SIMATIC Manager toolbar is turned on, clicking on the Accessible Nodes button shows you the simulated PLC that is currently open.
You cannot change the node address for the simulated PLC if you are using STEP 7 applications to monitor the program. Close these applications before changing the node address.
