r9782[0...1]
SI change monitoring time stamp (Control Unit)
Displays the time stamp for the checksums for tracking changes to Safety Integra‐
ted.
The time stamps for the checksums for tracking changes (fingerprint for the "Safety
logbook" functionality) at safety parameters were saved in parameters p9781[0]
and p9781[1].
[0] = SI change tracking, time stamp checksum functional
[1] = SI change tracking time stamp checksum, hardware dependent

Example:
r9794[0] = 1 (monitoring clock cycle)
r9794[1] = 2 (enable safety-related functions)
r9794[2] = 3 (F-DI switchover tolerance time)
...
The complete list of numbers for the crosswise compared data is listed in fault
