[etherlab-users] Problem setting up Etherlab Master with Wago 750-354

Mon Jan 28 14:26:12 CET 2013

Hello all,

So, it seems it started to work. 

I saw an old entry in the list where another user, with the same RT-PREEMPT and slave, was having the same problem:
http://lists.etherlab.org/pipermail/etherlab-users/2011/001177.html

I tried his solution (update the kernel):
http://lists.etherlab.org/pipermail/etherlab-users/2011/001182.html
and in addition to that, I started to use the e1000e driver (which corresponds to my hardware) instead of the generic driver.

Now, it seems to work (not fully tested though). At least, I can read SII and the XML from the slave. 

Thanks for your collaboration.

Diego

Thank you for your inputs.

I believe (not sure about that) it is something related with what Mike said, i.e., that the EEPROM was not burned with the SII. 
I used dmesg as Derrill suggested, and here is the output:

[30102.942757] EtherCAT: Master driver 1.5.1 0f7a243b03e4 [30102.942838] EtherCAT: 1 master waiting for devices.

[30102.968298] EtherCAT ERROR 0-0: Reception of SII read datagram failed: No response.
[30102.968303] EtherCAT ERROR 0-0: Failed to fetch SII contents.

[30106.228284] EtherCAT WARNING 0: 65 datagrams TIMED OUT!
[30106.228291] EtherCAT WARNING 0: 65 datagrams UNMATCHED!

So, the problem started in the reception of the SII read datagram, when there was no response. Could this be a problem of my configuration or definitelly the manufacturer of the slave that did not burn the EEPROm with the SII?

Thanks
Diego

Hello

are you sure you want to try this slave? This is a K-bus to EtherCAT coupler and it will take you quite some effort to configure this thing before you get to see any PDO's. Read the manual for the slave!

Richard
