RUN-P Command (Execute Menu)

Top 

Select the menu command Execute > Key Switch Position > RUN-P to put the simulated PLC in RUN-P mode. You can also do this by clicking the RUN-P check-box in the CPU view object.

In RUN-P mode, the CPU runs the program and allows you to change the program and its parameters. In order to use the STEP 7 tools for modifying any of the parameters of the program while the program is running, you must put the CPU in RUN-P mode. You can still use the view objects created within S7-PLCSIM to modify any data used by the program.
