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!
