Distributed Clock

The distributed clock represents a local clock in the EtherCAT slave controller (ESC) with the following
characteristics:

• Unit

1 ns

• Zero point

1.1.2000 00:00

• Size

64 bit

(sufficient for the next 584 years; however, some EtherCAT slaves only offer 32-bit support,

i.e. the variable overflows after approx. 4.2 seconds)

• The EtherCAT master automatically synchronizes the local clock with the master clock in the EtherCAT

bus with a precision of < 100 ns.

For detailed information please refer to the
