Product overview
Fig. 10: Marking in the TwinCAT System Manager
A configuration of FHC groups is possible only if at least 1 corresponding junction is present e.g.
EK1122-0080.
Distributed Clocks
If no Distributed Clocks functions are used, this is visible in the master settings by the absence of "DC in
use":
Fig. 11: DC master setting
This setting is automatically selected by the System Manager if there are no EtherCAT slaves in the
configuration in which Distributed Clocks is activated. "DC in use" should not be randomly deactivated by the
user, because otherwise these devices will no longer function.
