[etherlab-users] Emerson Control Techniques Drvive, No PDO exchange, WC=0

ecrt_domain_process and ecrt_domain_queue are called for both the input
and output domain.  
The code is below and the same code works with a different drive!  I am
using the latest etherlab 
driver and the ec_r8169.ko.

Does anyone have another suggestion after looking at the debug log

void cyclic_task(unsigned long data)
{
    unsigned short inputdata;
    static unsigned short ctrlword = 0;

    // receive process data
    down(&master_sem);
    ecrt_master_receive(master);
#ifdef ENABLE_INPUTS
   ecrt_domain_process(domainInput);
#endif
   ecrt_domain_process(domainOutput);
    up(&master_sem);


    if (counter) {
        counter--;
    } else { // do this at 1 Hz
        counter = FREQUENCY*10;///10;

        // calculate new process data
        // blink ^= 0xFFFF;
        blink *= 2;

        // check process data state (optional)
        check_domainInput_state();


        // check for master state (optional)
        check_master_state();

        // check for islave configuration state(s) (optional)
        check_slave_config_states();
        if (blink > 0x8000)
           blink = 1;

    }

    // write process data
    EC_WRITE_U16(domainOutput_pd + ofs_ctrlword_coe, ctrlword);
#ifdef ENABLE_INPUTS
    inputdata = EC_READ_U16(domainInput_pd + ofs_statusword_coe);
    if(counter == FREQUENCY*10)
      printk(KERN_ALERT "inputdata = %08X\n",inputdata);
    inputdata = EC_READ_U16(domainInput_pd + ofs_feedbackword_coe);
    if(counter == FREQUENCY*10)
      printk(KERN_ALERT "inputdata = %08X\n",inputdata);
#endif


    // send process data
    down(&master_sem);
    ecrt_domain_queue(domainInput);
    ecrt_domain_queue(domainOutput);
    ecrt_master_send(master);
    up(&master_sem);

    // restart timer
    timer.expires += HZ / FREQUENCY;
    add_timer(&timer);

    if(ctrlword == 0)
      ctrlword = 6;
    else if(ctrlword == 6)
      ctrlword = 7;
    else if(ctrlword == 7)
      ctrlword = 15;
}
