Viewing CPU Status Menu
With the View CPU Status menu, you can verify the S7-200 CPU RUN/STOP status and
check the CPU for fatal and non-fatal errors. The TD 200 displays the CPU mode first and
then displays the fatal and non-fatal errors sequentially.
The TD 200 displays an error message only if an error exists in the S7-200 CPU. The CPU
classifies errors as either fatal errors or non-fatal errors. Refer to the SIMATIC S7-200
Programmable Controller System Manual for more information about specific errors.
