Date and time synchronization
Two mechanisms are available for date and time synchronization:
●
Synchronization of the time used in the KNX network with the time of the LOGO! 8.
●
Synchronization of the time used in the LOGO! 8 with the time in the KNX network.
Note
•
The CMK2000 does not have a real-time clock. Depending on the parameterized
time/synchronization mechanism, the device fetches the time cyclically from the LOGO!
or from the KNX network and passes it on to the respective other side.
•
An unchanged transfer of the date only occurs between 1.1.2000 and 31.12.2089.
Parameter assignment options:
●
No synchronization (default)
●
KNX specifies the time and date
The settings for time synchronization made in the LOGO! are ignored.
●
LOGO! specifies the time and date
Synchronization of the time used in the LOGO! 8 with the time in the KNX network.
●
Following device start from CMK2000 or LOGO!
●
Following return of bus voltage
●
Cyclically every hour
●
Upon change in time
Note
The settings in LOGO! Soft Comfort with respect to date/time synchronization are made
independently of synchronization via KNX. In the event of an unfavorable configuration, both
time/date synchronization mechanisms act on the LOGO!.
