4.14 Time-of-day synchronization
Basics of time-of-day synchronization
With telecontrol application that require time-of-day synchronization, you need to
synchronize the time of day of the TIM regularly. If you do not synchronize the time of day,
there may be deviations of several seconds per day in the time information of the stations.
The TIM can obtain the time of day from an external source (for the methods see below) and
forward the time of day to the station or the connected WAN networks.
When using an external time source, the connected S7 station can obtain the current time of
day both via the CPU as well as via the TIM or a CP.
