[etherlab-users] Distributed Clocks and Sync0

I would like to gain a better understanding of how synchronization is achieved.

The current drive system we are using (Yaskawa Sigma V) uses DC Mode 1
(Sync0 Event with Input/Output Shift). I have attached two drives to the master
and wish to coordinate their actuation in time with each other.

The call ecrt_slave_config_dc(sc, assignActivateWord, cycle_time,
shift_time, ...)
sets up the slave for cyclic operation with the given timing parameters.

* If shift_time is set to zero for both slaves, does it mean that the
Sync0 events
on both slaves will occur at exactly the same time?

C-x C-s, C-x C-c
