8.2.2.3 Time synchronization for time stamping
Requirements
The following requirements apply to the time synchronization for time stamping:
● There must be a clock master, e.g. SICLOCK TM available in the automation system. It
● The time message frame must be forwarded:
● For the IM 153-2 (as of 6ES7153-2BAx1-0XB0) a synchronization interval of 10 s must be
Time synchonrization for highly precise time stamping with 1 ms precision
You must realize the time synchronization for the highly precise time stamping with the
following hardware components and settings:
● Time master: SICLOCK TM (as of FW V3.3.0090) with GPS synchronization

must work with synchronization intervals of 10 s.
– via Ethernet e.g. to a CP 443-1
– on PROFIBUS DP e.g. via an integrated DP master or CP 443-5 Extended
