This tab can be used for the distributed clock settings. The EtherCAT slave can be operated in FreeRun
mode or DC Synchronous mode.
No. Description
1 Here you can change the settings for the Operation mode. You can choose
between FreeRun and DC Synchronous mode.
2 The Advanced Settings button opens a further window with additional
settings for the distributed clocks function.
EtherCAT slaves feature integrated local clocks, which are synchronized by the EtherCAT master via special
datagrams. For sample, the local clock of an EtherCAT slave can be used as reference clock, based on
which all other clocks are synchronized.
By default, TwinCAT sets the first EtherCAT slave that supports the distributed clocks function as reference
clock. This setting can be changed, although we recommend retaining the default setting.
