Clock time operation
When using setting “Autonomous“, the device does not receive or send the
time of day. If the system is to use a common time of day, one of the devices
must be defined as the clock time master and the others as slaves.
Main menu > Commissioning > Bus communication
> Time of day/date > Clock time op:
Factory setting Autonomous
Your setting  Autonomous
 Slave
 Master
Ensure that only one device in the system is defined as the clock time
master.
Remote setting clock slave
Function “Remote setting clock slave = Yes“ enables the user to also set the
time of day and the date on a clock time slave.
The new values are transmitted to the clock time master via the Konnex bus.
The clock time master distributes the new time to all bus users. Hence, for the
plant user, operation is the same as that on the clock time master.
