There is no waiting inside the ecrt_master_receive() function. If a
packet is not there by the time this function is called, you get an
error. You need to do the waiting in your program.

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!
