How to set the DC synchronisation:
1. Configure the synchronisation of the EtherCAT slaves via distributed clocks (DC).
• Set the Distributed clocks (DC) cycle time at the EtherCAT Master:
• The DC cycle time to be set in the »EtherCAT Configurator« must be identical to
the EtherCAT task cycle time set in the »PLC Designer«.
• Select the cycle times, according to the technical data, between 1 and 10 ms.
• The (basic) cycle time set here is valid for all Logic and Motion nodes
synchronised by distributed clocks.
