Status and error displays

Diagnostics by means of LEDs is a basic tool for troubleshooting. Usually, you can pinpoint
the source of error more precisely by analyzing the module status information in STEP 7, or
in the diagnostic buffer of the CPU. These locations contain the corresponding error
information in plain text.
