[etherlab-users] A question about ecrt_master_reference_clock_time

[Mohsen Alizadeh Noghani]

Hello everyone.

When "ecrt_master_reference_clock_time" is called, does EtherCAT
Master read the reference clock at that instant (i.e. it communicates
with the reference slave specifically for reading its clock), or does
the clock value already exist in the datagram received by
"ecrt_master_receive", and thus function just parses the datagram?

Best,
Mohsen
