15.2 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.
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.
