int ecx_srconfirm | ( | ecx_portt * | port, |
int | idx, | ||
int | timeout | ||
) |
Blocking send and receive frame function. Used for non processdata frames. A datagram is build into a frame and transmitted via this function. It waits for an answer and returns the workcounter. The function retries if time is left and the result is WKC=0 or no frame received.
The function calls ec_outframe_red() and ec_waitinframe_red().

const uint16 priMAC[3] |
Primary source MAC address used for EtherCAT. This address is not the MAC address used from the NIC. EtherCAT does not care about MAC addressing, but it is used here to differentiate the route the packet traverses through the EtherCAT segment. This is needed to find out the packet flow in redundant configurations.
