[etherlab-users] Beckhoff 6731-0010 initialization

[Gavin Lambert]

Most likely, there is something invalid in the parameters for the SDO
configuration functions.  You’ll need to post all of the related code if you
want help in locating it.

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:

I'm not sure is there is the correct information to know whats happens, tell
me any doubt.

 

Thank you very much

 

King regards
