Distributed Clocks

In DC mode (Distributed Clocks) the process data 0x1A03 Timestamp must be activated.

Distributed Clocks 1:
EL3356-0010, EL3356-0090 activation timestamp 0x1A03 in DC mode

Also, the variables DcOutputShift and DcInputShift are displayed in the process data in DC mode. Upon activation of the configuration these are calculated once in the unit [ns] on the basis of the set EtherCAT cycle time (observe assigned task!) and DC shift times from the EtherCAT master settings. In the InputBased operating mode, DcInputShift indicates by how many nanoseconds [ns] before or after the global Sync the terminal determines your process data. For further information on this, see the EtherCAT system description.

Since the EL3356-0010 and EL3356-0090 are not DC-triggered but determine the timestamp itself, these values have no meaning in these terminals.
