RUN Command (Execute Menu)

Top 

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

In RUN mode, the CPU runs the program by updating the inputs, executing the program, and then updating the outputs. You cannot download any program or use the STEP 7 tools to change any parameters (such as input values) when the CPU is in RUN mode. You can still use the view objects created within S7-PLCSIM to modify any data used by the program, as in RUN-P mode.
