8 Operation
This chapter describes how to handle and diagnose the controller during its operation.
8.1 Handling
The controller needs not be handled during its normal operation. Only if problems arise, an
intervention with the PADT may be required.
8.2 Diagnosis
A first, rough diagnosis can be performed via the light-emitting diodes (LEDs). The diagnostic
history that can be displayed using the programming tool provides a more detailed analysis of
the operating or error state.
8.2.1 Light-Emitting Diode Indicators
The light emitting diodes (LEDs) indicate the module state. Function and meaning of the LEDs
depend on the processor system's operating system currently in use. Refer to the device-
specific or module-specific manuals for details.
The function and meaning of the fieldbus LEDs are described in the communication manual.

8.2.2 Diagnostic History
The diagnostic history records the various states of the processor system and communication
system and stores them in a non-volatile memory. Both systems include a short term and a long
term diagnosis. The number of entries differs for hardware layout and the operating system
versions:
Number of entries in the long term
diagnosis
Number of entries in the short term
