Hi Jon,

Change is to ethercat-1-5-3/ethercatApp/scannerSrc/scanner.c:

diff scanner.c.original scanner.c
162a163,167
>             // gets reply to LRW frame sent last cycle
>             // from network card buffer
>             ecrt_master_receive(master);
>             ecrt_domain_process(domain);
> 
170,173d174
<             // gets reply to LRW frame sent last cycle
<             // from network card buffer
<             ecrt_master_receive(master);
<             ecrt_domain_process(domain);

Thanks,
Damien

Hi Damien,

Yes I have.  I have a fairly basic system running (Linux, EtherLab, r8169, DLS ethercat) and those messages are continuous as long as the scanner is running.  I had been meaning to look into it, but since the ethercat communications were working fine I figured it was a low priority.  I'd be happy to test out your changes if you'd like independent verification.  The system is currently running but the hardware it's connected to is not being used for anything important for a little while.  Cheers,

Jon
