[etherlab-users] Ethercat/ProfiNet - add correct slave configuration to program

Ok, we got it  running:

We had to convert the CoE strings manually to a char array and pass it
to the ecrt_slave_config_complete_sdo().

Strangely it didn't work directly with the strToCharArray function, but
we used it to generate the char arrays. See source attached.

Snippet of our modified and working main.c:

/* EL6631 Master */
    if (!(sc = ecrt_master_slave_config(master, ProfiNetPos,
ProfiNetTerm))) {
        fprintf(stderr, "Failed to get slave configuration.\n");
        return -1;
    }

unsigned char pn_config_buf0[] =
{0x0F, 0x00, 0x01, 0x00, 0x65, 0x6C, 0x36, 0x36, 0x33, 0x31, 0x2D, 0x70,
