[etherlab-users] working counter error after long time running

[yangmin]

Dear all,

 

         I am running etherlabmaster-9cdd7669dc0b as the master to drive all
the slaves from Beckhoff(including servo drives and IO modules). Every time
when it is just started, the whole system can work very well. But errors
happen after a long time running(about 20-35 hours later). Part of the error
message is showing below:

 

[69814.062218] EtherCAT 0: Domain 0: Working counter changed to 14/14.

[69847.925696] EtherCAT 0: Domain 0: Working counter changed to 13/14.

[69848.925673] EtherCAT 0: Domain 0: Working counter changed to 14/14.

[70486.257039] EtherCAT 0: Domain 0: 3 working counter changes - now 14/14.

[70519.220480] EtherCAT 0: Domain 0: Working counter changed to 13/14.

[70520.221400] EtherCAT 0: Domain 0: Working counter changed to 14/14.

 

Such errors will never stop but become worse and worse until mater stops. 

 

When above errors happen, I never saw any error or warning about DC in
master or slave, but I noticed the feedback of one servo drive (AX5201) is
unreasonable even I put it into a separate domain. At the beginning I
considered it as hardware problem, but after changing another AX5201, the
problem is still the same. I have to concentrate on the software again. Can
you give some suggestions about my problem? Any clue is welcome. Thanks in
advance.

 

Maggie
