Synchronization - Siemens LOGO! Manual

Programming LOGO!
3.7 Writing and starting the circuit program
You have now customized the summertime/wintertime conversion. The LOGO! onboard
display now shows:
LOGO! indicates that summertime/wintertime conversion is enabled, and that user-defined
parameters ( '..' ) have been set.
Note
To disable summertime/wintertime conversion in this menu, you merely confirm 'Off' with OK.
Note
Summertime/wintertime conversion only functions when LOGO! is operating (in RUN or
STOP status). It does not function when LOGO! is in buffered operation (Page 116).
3.7.15

Synchronization

Time synchronization between LOGO! and a connected communication module EIB/KNX
(version 0AA1 upwards!) can be enabled/disabled
● in parameter assignment mode by means of the set menu ("Clock" menu item)
● in programming mode by means of the setup menu ("Clock" menu item).
When synchronization is enabled, LOGO! can receive the time-of-day from a communication
module EIB/KNX (version 0AA1 upwards).
Whether synchronization is enabled or disabled, the time-of-day is always sent to the
expansion modules at power-up, every hour (STOP mode or RUN mode), and when the time
of day is changed (after a 'Set Clock' is executed or after a summertime/wintertime
conversion).
Note
When using a LOGO! Base Module with digital or analog expansion modules, but without
communication module EIB/KNX (version 0AA1 upwards), time synchronization must not be
activated! You must check whether time synchronization is deactivated ('Sync' must be set to
'Off').
