Time-of-day synchronization
Time-of-day synchronization for the CMR can be configured using three time-of-day
synchronization methods.
The time-of-day synchronization method is set in the configuration on the "System" page in
the "System time" (Page 58) tab:
● Synchronization with an external NTP server accessible via the mobile wireless network.
● Time of day from the GPS signal: The GPS antenna must be connected.
● Time of day from the mobile wireless network
The availability of the time of day depends on the mobile wireless provider.
Note
The CMR does not set itself automatically
to a time of day synchronization method. You
eed to select a time of day synchronization method in the configuration.
-of-day synchronization of the BM via the CMR, disable the standard/daylight
saving setting on the BM to ensure a consistent time.
If you enable the time of day in the WBM, you can also make a setting in the WBM so that
the CMR also synchronizes the BM with the time of day (time-of-day forwarding).
"Forward time of day to LOGO! BM " is enabled:
Even if time-of-day synchronization is disabled, the time of day is forwarded to the LOGO!
BM . In this case, only the manual settings are transferred to the LOGO! BM .
