2.5 Easy to change the operating mode of the CPU
The CPU does not have a physical switch for changing the operating mode (STOP or RUN).
Use the "Start CPU" and "Stop CPU" toolbar buttons to change the operating
mode of the CPU.
When you configure the CPU in the device configuration, you configure the start-up behavior
in the properties of the CPU (Page 76).
The "Online and diagnostics" portal also provides an operator panel for changing the
operating mode of the online CPU. To use the CPU operator panel, you must be connected
online to the CPU. The "Online tools" task card displays an operator panel that shows the
operating mode of the online CPU. The operator panel also allows you to change the
operating mode of the online CPU.
The color of the RUN/STOP indicator shows the current operating mode of the CPU. Yellow
indicates STOP mode, and green indicates RUN mode.
