Hi, All.
This topic has been discussed 2011 in
but I still meet many problems.
1. When I use ecrt_slave_config_idn(), the code all has been execute correctly,but  I can't sniff any SoE fragment with Wireshark.
2.When I replace ecrt_slave_config_idn() with ecrt_master_write_idn(), the SoE fragments are sent to slave correctly
but idn 'P-0-150'. idn 'P-0-150' is 228 bytes, the master just sent the first 118 bytes, and lose the left 110 bytes.
3.When I change the configration of SM, it also doesnot work.
my code is as follows:
#include "ecrt.h"
static ec_master_t master = NULL;
static ec_domain_t domain1 = NULL;
//1.IDN15--user define
static uint8_t idn_15[]={
//2.IDN16--AT List
int main(int argc, char **argv) {
    ec_slave_config_t *sc;
    master = ecrt_request_master(0);
    if (!master) return -1;
    domain1 = ecrt_master_create_domain(master);
    if (!domain) return -1;
    if (!(sc = ecrt_master_slave_config(master, 0, 0, 0x00000002, 0x13ed6012))) {
        fprintf(stderr,"Failed to get slave configuration.\n");
        return -1;
    ecrt_slave_config_idn(sc, 0, 15, EC_AL_STATE_PREOP, idn_15, 2);
    if (ecrt_slave_config_pdos(sc, EC_END, AX5101_syncs))  return -1;
    if (ecrt_domain_reg_pdo_entry_list(domain1, domain1_regs)) return -1;
    if (ecrt_master_activate(master)) return -1;
    if (!(domain1_pd = ecrt_domain_data(domain1))) return -1;
