Reading out/saving service data

Service data
In addition to the contents of the diagnostics buffer, the service data contain numerous
additional data points about the internal status of the CPU. If a problem occurs with the CPU
that you cannot resolve with other methods, send the service data to the Product Support
team. The Product Support team will use the service data to help you with problem analysis.
Please note the following:
• Read out the service data in the following cases:
– Immediately after a CPU has switched to the STOP operating state.
– Immediately after a loss of synchronization in the redundant system.
• Always read out the service data of the primary and the backup CPU.
NOTE
You cannot execute a download to the device while reading out the service data of the CPU.
Requirement
The S7-1500R/H redundant system must not be in the SYNCUP or RUN-Redundant system
state.
Methods of reading service data
You can read service data with:
• STEP 7
• SIMATIC memory card
Procedure using STEP 7
You can find more information on saving service data with the keyword "Saving service data"
in the STEP 7 online help.
Procedure using the SIMATIC memory card
Use the SIMATIC memory card to save the service data if communication with the CPU is not
possible over the Ethernet. In all other cases, save the service data using STEP 7.
The procedure using the SIMATIC memory card is more time-consuming than the other
S7-1500R/H redundant system
