[etherlab-users] Slaves don't go into the OP state

I am using EtherCAT master 1.5.2 kernel module on RT-Preempt, and am using
EPOS3 slaves provided by Maxon. When I give the sdo commands through the
terminal, I am able to get the motors to run, but the slaves remain in the
Pre-op state. I am confused - if the motors are running by sending in the
correct sdos, shouldn't the slave be in the OP state? This might precisely
be the reason why I am unable to run the motors through Simulink model.
I can't seem to find the error in all this. I'll be grateful if anyone
could help me out here.
