The information of Clock_Value_Status1 and Clock_Value_Status2 is used for the
transmission of time corrections (C and CV), the synchronisation status (SYF), the
daylight saving time information (ANH and SWT) and the accuracy (CR).
Process alarm
The diagnostic telegram is used to signal to the master that a time-stamped event
has been recorded. The actuator only supports process alarms.

Read time-stamped data
The data record signalled via a process alarm (slot 0 index 100 to 115) can be read
using the Profibus DP-V1 services once the alarm has been acknowledged.
A data record may contain up to 17 alarms, each data record consists of 14 bytes.
