esi_write lost after reboot was created by zmrdko
Hi, using command
Code:
ethercat slaves my devices looks like this: [attachment=60926]ethercat_slaves_before.png[/attachment] I was somehow able to generate sii binary file from XML file provided by Delta: [attachment=60927]xml_file.png[/attachment] and upload it to my Delta B3-EtherCAT drive using [code]ethercat sii_write and after [code]ethercat rescan it shows up correctly: [attachment=60928]ethercat_slaves_after.png[/attachment] However, after restarting servo drives, the changes are lost and I am back to 0x000001dd:0x00006080.What am I missing? Thanks

Maybe try saving parameters on the device and see if that helps? It's kind of the wrong layer, but it might trigger the right behavior anyway.

 Do you mean P3.012?

I tried setting p3.012 to 0100 to use eeprom values, but it did not make any difference

I wonder if this is related? forum.linuxcnc.org/ethercat/47710-wago-7...ules?start=10#262402

"Be aware that there are many delta ec02 with a faulty SII Eeprom out there..."

It's a different Delta model, but "faulty SII EEPROM" would explain things.

Im in contact with Delta support. The main issue is missing Digital output PDO 60FEh.
I also described issue with sii changes wanishing after reboot and the reply was:

Which data do you need to write? I'm asking because you can't write all EEPROM in B3 servo drives, only the essential ODs. The design of the servo drive does not allow you to have the same data after rebooting, except for the write-allowed ones. So, you may see it like that.

According to Delta support response, Delta B3 servo drives are not made to store sii permanently.
However after firmware upgrade, the drives are listed with correct name.
