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

[BOESEL Diego Fernandes]

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.
[30102.947491] ec_generic: EtherCAT master generic Ethernet device module 1.5.1 0f7a243b03e4

[30102.956267] EtherCAT WARNING 0: 1 datagram TIMED OUT!
[30102.957270] EtherCAT 0: 1 slave(s) responding.
[30102.957272] EtherCAT 0: Slave states: INIT.
[30102.960309] EtherCAT 0: Scanning bus.
[30102.967301] EtherCAT ERROR 0-0: Reception of SII read datagram failed: No response.
[30102.967307] EtherCAT ERROR 0-0: Failed to determine SII content size: Reading word offset 0x0040 failed. Assuming 64 words.
[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.
[30102.968305] EtherCAT 0: Bus scanning completed in 11 ms.
[30105.001035] EtherCAT WARNING 0: 93 datagrams TIMED OUT!
[30105.001042] EtherCAT WARNING 0: 93 datagrams UNMATCHED!
[30105.212030] EtherCAT ERROR 0-0: Failed to receive AL state datagram: Datagram timed out.
[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
