Utc analog clock for windows 107/31/2023 ![]() The clock of the first EtherCAT slave in the topology that supports distributed clocks is usually automatically selected as reference clock. This reference clock is usually one of the EtherCAT slave clocks, not the EtherCAT master clock. in the system one of the existing clocks is selected as reference clock and used for synchronizing all other clocks.such a clock also runs in the EtherCAT master, in this case software-based.If the EtherCAT master does not support this feature, DC is also ineffective in all slaves. If a slave does not support this concept, the master will not include it in the synchronization. Not all EtherCAT devices have to support this feature.The EtherCAT master must keep the distributed clocks synchronous within the system accuracy (EtherCAT: 1 ns time resolution corresponds to 1 digit, scope of 64 bits corresponds to approx. ![]() Synchronization of local EtherCAT devices
