To ensure that TwinCAT uses such a component as DC reference clock, a manual intervention during the
configuration setup is required, as shown here using the EK1100 as an example.
The checkboxes "Cyclic Mode Enable" and "Use as potential Reference Clock" must be set.

Activation of Distributed Clocks support
The (synchronization) procedure described here is only successful for the components described
above. The checkboxes can be set for other components, too, although the hardware does not
support this function, unless specified in the respective documentation. In particularly, please note
that after commissioning the component may not be replaced with a previous version without DC
support.
