Hello,
DC is a little bit more difficult than normal io.
First there are some questions:
- Which Realtime Subsystem do you use? (RTAI, Xenomai, Preempt)
- Which CPU do you use?
- Which NIC driver do you use?
- Which etherlab master version do you use?
- What is your system latency? (RTAI/testsuite)
- Which slave do you want to use?
About OP State
try to set
ethercat debug 1
and start your application and post the dmesg output.
Best regards
Andreas

Hi all,
I have problems when running the examples in DC, both in real time and
without it.
I modify the examples to suit the device I have, so I set a module
digital output (Beckhoff EL2004).
The problem is that the slave never goes to OP state, without giving
any error message,
but if I comment the line of code:
'ecrt_master_application_time (master, EC_TIMEVAL2NANO (tv))'
so that I'm not updating the time of application, the slave goes to OP
state and work
correctly, but I get the error line:
"EtherCAT ERROR 0: Received app_time not up to now, But Already active
master). '
Does somebody know why doesn't the Ethercat slave go to OP state when
using the
ecrt_master_application_time method?
Thank you
Mit freundlichem Gruß
Andreas Stewering-Bone
