[etherlab-users] Beckhoff EL3104 - Problem while setting OP state

[hamelin.philippe at ireq.ca]

Hi again,
 
I have to specify one important thing: the final state of the EL3104 isn't SAFEOP + ERROR, but only SAFEOP. However, the master reports an error during configuration, i.e.:
 
$ sudo ethercat slaves
0  0:0  OP      +  EK1100 EtherCAT-Koppler (2A E-Bus)
1  0:1  SAFEOP  E  EL3104 4K. Ana. Eingang  +/-10V Diff.
 
Thank you,
 
Philippe

Objet : [etherlab-users] Beckhoff EL3104 - Problem while setting OP state


Hello,
 
I'm trying to setup DC synchronization with the EL3104 ethercat module. For testing purpose, I just slightly modified the "dc_user" in order to support only the bus coupler and the EL3104. The problem is that I have a timeout while setting OP state, and thus it goes to SAFEOP + ERROR state. I tested both the official 1.5.1 release and the current tip version (c0b4c64fcebd). I'm using Linux kernel 3.4.4 with RT-PREEMPT patches and the generic driver. I attached the dmesg output and the test program.
 
What could be the reason why the EL3104 can't do the transition from SAFEOP to OP?
 
Thank you for your help,
