6.3.7 Read and Set Date / Time
You have already decided in Chapter 4.7.2, page 85 on date and time management
whether to set the internal clock and which synchronization source to use.Usually, a
plausible time is already displayed during the device start. The time is either set auto-
matically by the connected synchronization source or manually. Until the synchroniza-
tion takes place and sets a valid time, different time displays may appear on the de-
vice. They are as follows:
The bay units are automatically synchronized via the central unit. For the operation
without a central unit, the time for the bay units can be set via DIGSI or via local oper-
ation.
Clock status Besides the display of date and time also the clock status is indicated. The text of the
status display may look as follows for regular states of the time management:
