Reading service data
Application case
If you need to contact Customer Support due to a service event, the department may require
specific diagnostic information on the CPU status of your system. This information is stored
in the diagnostic buffer and in the service data.
Select the "PLC -> Save service data" command to read this information and save the data
to two files. You can then send these to Customer Support.
Note the following:
● If possible, save the service data immediately after the CPU goes into STOP or the
● Always save the service data of both CPUs in an H system.
Procedure
1. Select the "PLC > Save service data" command.
2. Save the files.
3. Forward these files to Customer Support on request.

Response to fault detection
Response to fault detection
In order to ensure a high level of reliability, in particular, of the fault tolerant system, the CPU
410 has many self diagnostics. Faults can thus be detected and eliminated at an early stage.
In the rare instance that a fault occurs that cannot be eliminated by the firmware, the current
status data can be saved internally (memory dump) for further evaluation by SIEMENS
specialists. An automatic reboot is then started. This behavior minimizes the down time of
the CPU and guarantees the fastest possible restoration of access to the process.
Automatic reboot in the event of a one-sided defect in the fault-tolerant system
The defective CPU performs the complete self-test. The other CPU remains in RUN. If a
hardware error is detected, the CPU remains in DEFECTIVE. If no fault is detected, the CPU
links up again. The fault-tolerant system switches back to the redundant system state.
The necessary defect information can be read out immediately afterwards during operation
with the function Read out service data.
