Time synchronization
Time synchronization ensures that all clocks in a system are set to the same time. In addition,
in a configured cycle, a time master distributes the time to all the other components in the
automation system that possess a clock. The components then use the distributed time to set
their respective clocks.
Update
After performance or (compatible) function enhancements you should update the interface
module IM 153-2 to the latest firmware version.
