Hi,
Just a question or two about distributed clocks.
I have a system with an EL1008 digital input module, EL3001 analogue input
module, two EL7031 stepper motor driver modules and two EL2008 digital output
modules in that order. I am using the EK1100 bus coupler terminal as the first
module.
Do I need to call ecrt_slave_config_dc() for all of these modules before
activating the master, or just the first module on the bus? My understanding
from reading about distributed clocks is that the first module on the bus with
DC capability should be used as the reference clock.

In the cyclic_task(), the functions ecrt_master_application_time(),
ecrt_master_sync_reference_clock(), ecrt_master_sync_slave_clocks() are then
called in that order. I notice ecrt_master_reference_clock_time() is not used
at all here.
Is this all that is required to control the distributed clocks ? Thank you in
advance.
