Distributed clocks (DC) is a differentiating feature of the EtherCAT network. Distributed clocks allows all the SubordinateDevice nodes in the EtherCAT network to be bound in a tight margin of time to synchronize the events and the EtherCAT MainDevice command.
This feature has sub-features as listed below. To enable the utility of these features at the application level, the related signals of DC are integrated tightly with the C2000 control loop logic, as well as, an external component that can be a possible implementation to trigger/latch other components on the board. This section explains the integration of these signals and related nuances of usage.
Distributed clock features:
Apart from usage for control loop synchronizations, these features are also used to synchronize the system and network time. These include the following:
