DC (Distributed Clocks)

In the "DC" tab, the trigger mode can be set via the Operation Mode selection list.

• FreeRun: (frame-triggered)
  Cyclic operation is started via the SyncManagers during EtherCAT frame processing.
• DC-Synchron:
  Cyclic operation in the module is started by the local distributed clock at exact intervals. The start time is chosen such that it coincides with other output slaves in the EtherCAT system.
  This mode is not suitable for the EJ5021 EtherCAT plug-in module as a module of the DC group of input modules, see Note.
• DC Synchron (input based):
  As DC Synchron mode, with the cyclic start time chosen such that it coincides with other input slaves in the EtherCAT system.

A detailed description of the function can be found in the chapter "Operation mode (Trigger mode)"
