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 ________________________________

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, ------------------------------------ Philippe Hamelin, ing., M.
