Non-Beckhoff pluggable IO modules

Hello，I recently bought a device similar to the Beckhoff EK1100 and he works fine on Twincat, but I only have the coupler on the IGH and I can't see the module, I put the detailed output in the attachment. The xml is the official ESI, and the others are the output of IGH.

If you can provide ideas, I would greatly appreciate it

Oh dear... this reminds me of my attempt getting Kbus elements to work on an BK1120. See here: forum.linuxcnc.org/ethercat/45587-gettin...-coupler-operational

Due to being on the road I can't help at the moment, hence just a few notes:
- The hardware you have bought is likely not using ethercat as an internal bus but rather something else - CAN maybe?
- Accordingly, the ethercat master will not see them as salves, instead, the coupler provides registers to read from
- Back then I used an xml export from twincat that helped me (and especially dbraun1991) to work out what these registers where.

Hopefully this serves as an inspiration to look at.

Ok, I will refer to the previous post and thank you for your help. I do see a lot of SDOs. Maybe I need to manually configure pdo. Thank you for your help. Please accept my most sincere thanks.

Hi,Guihue.I've carefully read the link you sent, but I still don't know how you solved it, By turn on the device first, and wait a few seconds before connecting to ethercat?

I just tried it and nothing has changed

Hello,I was also working with Delta RTU-ECAT and faced same issue.Now with some efforts I could able to make it working.

Hello,Msantaji1，It seems that your configuration file is manually configured pdo. I can successfully display pdos in "ethercat pdo" by operating the sdo 1c12, but I still can't op it.

In a word, thank you for providing the configuration file and guiding me.

hello,

check below command output in terminal 

sudo dmesg

is it showing slave in OP mode?
refer attached snap
