DCF-77
The DVS-21 system clock can be synchronized with a DCF-77 receiver. The following soft- and hardware
versions are required:
Hardware
CPU1
(05.09.2007) manual change required
DCF-77 Receiver
ProCom DCF-77 Radio clock module
Software
CPU1
Firmware as from Version 7.27
PIC
as from Version 5113
ICS
as from Version 7.00 Rev.012
The DCF-77 receiver is connected to the upper SUB-D9 port of CPU1.
The DCF-77 option activates the function and is configured by means of the expanded dialog.
DCF-77 Synchronization
Synchronization takes place either hourly or at a fixed time, always on the
hour.
DCF-77 (not found)
If the receiver is not connected or does not answer, a Line and/or a Flag
switches for further use of this information. The Summary fault option
triggers the internal genera fault.
DCF-77 (no synchronization)
The "no synchronization" report by the receiver switches a Line and/or a
Flag for further use of this information. The Summary fault option triggers
the internal general fault.
Note! The DCF-77 receiver is deactivated during an active ICS session!
Tip! Synchronization of all connected systems can take place in conjunction with the System Time
program and just one DCF-77 receiver!
