[etherlab-users] Beckhoff 6731-0010 initialization

[David Jiménez Mejías]

Dear Wilhelm,

I was reading your replies to this issue at the EtherLab-Users mailing list 
and it was very helpful for me.
http://lists.etherlab.org/pipermail/etherlab-users/2012/001860.html

I'm trying to configure a Can Network from the Beckhoff Can Master Module 
EL6751 with only one can slave (Phoenix Contact Can I/O Terminal).

I just do it the steps like the configuration of the EL6731 (Profibus Master 
Module):
     - Configure the Can Network with TwinCAT
     - Export the XML
     - Format it with xmllint
     - And take the necessary data:
          * PDOs Entries: Tx and Rx
          * StartUp SDO config of the next Index:
               + 0x1C32
               + 0x1C33
               + 0xF800
               + 0x8000
               + 0x8001
               + 0x8002
               + 0x8003
     - Implement the C code for the configuration, but I keep out from the 
app without error at the function: 
          * ecrt_slave_config_complete_sdo(sc, 0x1C32, pb_config_buf, cnt);

The last dmesg is:
