18.2 Displaying and Changing the Operating Mode
With this function you can, for example, switch the CPU to RUN again after correcting an error.
Displaying the Operating Mode
1. Open your project and select an S7/M7 program, or open the "Accessible Nodes" window
using the menu command PLC > Display Accessible Nodes and select a node ("MPI=...").
2. Select the menu command PLC > Diagnostics/Settings > Operating Mode.
This dialog box displays the current and the last operating mode and the current setting of the
mode selector on the module. For modules for which the current keyswitch setting cannot be
displayed, the text "Undefined" is displayed.
Changing the Operating Mode
You can change the mode of the CPU using the buttons. Only those buttons are active that can be
selected in the current operating mode.
