Reading Service Data - Siemens SIMATIC CPU 410 System Manual

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, read out the service data immediately after the CPU goes into STOP or
immediately after the synchronization of a fault-tolerant system has been lost.
● Always read out the service data of both CPUs in a fault-tolerant system.
Procedure
1. Select the "PLC > Save service data" command.
In the dialog box that opens up, select the file path and the file names.
2. Save the files.
3. Forward these files to Customer Support on request.
Note
Customer Support may also request a readout of the security events for diagnostic purposes
in the service case. You can store the security events as a text file with:
>Simatic Manager - PLC - Save Security Events
