Time synchronization for time stamping

Requirements
The following requirements apply to the time synchronization for time stamping:
● There must be a time-of-day master, e.g. SICLOCK TM, available in the automation system
that operates with a synchronization interval of 10 s.
● The time-of-day frame must be passed via the PROFIBUS DP interface of the CPU.
● A synchronization interval of 10 s must be assigned for the IM 650.
Time synchronization for high-precision time stamping with 1 ms accuracy
You must realize the time synchronization for the high-precision time stamping with the
following hardware components and settings:
● Time-of-day master: SICLOCK TC 400 with GPS synchronization
Parameters to be set for SICLOCK TM:
