[etherlab-users] puzzle about ecrt_master_receive in cyclic_task

[Yin]

Hi everyone, I have found the ethercat master will do some regular sending and receiving job
to scan slaves on the bus when it was started. But when we run our application program, the
ecrt_master_receive will be first executed in cyclic_task function and  do sending in the last,
that meas it can't receive frame sent by application program itself.
So I want to know when the cyclic_task function be first executed, does the ecrt_master_receive
will receive any frame or wait for a while and at the same time the master itself will also send and receive
its own frame?
Thanks a lot for attention!
