Hello,
I am trying to get a digital output from KL2012 (with Buscoupler BK2012).
Configuration is done without errors. My cyclic task looks as follows:
(similar to the user example)
/**********************************************************************************
ecrt_master_receive(master);
ecrt_domain_process(domain1);
if (counter) {
counter--;
} else { // do this at 1 Hz
counter = FREQUENCY;
check_domain1_state();
check_master_state();
check_slave_config_states();
printf("Nach %d Sekunde; Inhalt Domain1: %d\n", ++i, *(domain1_pd +
offset[0]));
*(domain1_pd + offset[0]) ^= 0xff; //same problem with ...^= 0x1;
}
ecrt_domain_queue(domain1);
ecrt_master_send(master);
getchar();
**********************************************************************************/
Unfortunately the I/O Error LED of the Bouscoupler indicates failure. After
starting the timer in the application, the I/O Error LED switches on for about
an
half second. After this a short light impulse is emitted by the I/O Run LED.
I suppose thats the impact of another problem: calling
"ecrt_master_receive(master);"
in the cyclic task causes the setting of the slaves error flag. (from '+' to
'E')
If necessary, you can find a summary of the configuration below.
Any suggestions are welcome.
Regards
Oliver
