new hardware trouble

Hi,

I found a sophisticated solution..ethercat master igh(which one we already using) has eoe enabled from default.. it should be set during installation itself .. --enable generic --disable 8190too etc... when u add a --disable eoe... It will newer use them.. read ethercat master igh manual for more details

Let me know

Regards

There is also a simpler way to turn off eoe by modifying the parameters in the firmware

Yes, I saw that it could be disabled. Unfortunately I need to use it at least during commissioning because the drives I have can only communicate with the drive commissioning utility with EoE...otherwise CoE has to be disabled and it's like the chicken before the egg problem.

For quick check just try something to solve the problem easy.. for long term solution are possibilities here too

I like long term solutions but for troubleshooting u know...

I have found that when sending config pdos to the drive it is successful in LinuxCNC but then lcec dies because it can't map some of the pdos that were just configured.  If you do an "ethercat rescan" then the pdos are shown and LinuxCNC starts just fine.  I'm not sure if this is an linuxcnc-ethercat or etherlab ethercat-master issue.  This may still be some type of interaction with EoE but out of curiosity @endian could you please try seeing if that works for you as well vs disabling EoE?

LinuxCNC was not running during the following commands:

hi,

I do not know what exactly means lcec dies ... but command should restart your died ethercat service on your host PC...

I did that what I mention in the posts before... we are not in the situation that we are able to use FAoE, AoE or EoE .. but that time should come soon

My symphtons of not working ethercat service because of EoE on was that... sometimes communication between ethercat slave was turned on(less attemps) and comm was 0 (more attempts) .. but behavior was trully randomable... other slaves on bus was in opmode normally with EoE slave on the bus in same time ...
