I did only skip read this thread which I found searching for EL2004.
Are you still using this Beckhoff component? I have found that it likes to not work with linuxcnc-ethercat as the implementation in EL2xxx.c is faulty. It uses the same index as for other EL2xxx (0x7000) but that is not correct.
I came across the error while looking at sudo dmesg.
Might be worth looking into (if you are still at it).

what kind of errors do you get?
At my configurations el2004s are working, and 0x7000 is the correct offset for Channel 0.
What is the Hardware / Software Rev of your card?

Very interesting remark - I have only looked at the reference XML at the Beckhoff site, where I found a different Index (donÄ't have it with me right now).
How can I determine HW/SW rev?

in Twincat system Manager
or with etherlab
"ethercat slave -p(pos number) -v"

strange...
i'm shure this error is not EL2004 related, there must be some config pod count mismatch in front of the el2004. or the content of the SII Eeprom / Firmware has been reflashed and something went wrong. the rev and serial register should hold values....
Which devices are mounted in front of the el2004?

I tried a minimal setup. Its just an EK1100 and the EL2004.
groot@grootethercat:~/linuxcnc/configs/sim.axis$ ethercat slaves

I had the EL2004 in the mix with other devices. No problem there as long as I don't include it in the startup. To me the error regarding 0x7000 appears to point at the some problem all the time.
Another Update:
I installed TwinCat3 on a WindowsMachine and got it talking to the ethercat system:
It can manually trigger stat eand outputs just fine.
I exported the xml config. Shows no index 7000 anywhere - but a x3001:1 (to 4)

interesting, i just ad an el2004 to an Twincat2 Project and there the offset is 0x7000
What gives the output of "ethercat pdos -v -p"

As expected: 1600
I guess the easiest way is to use a generic config...
I guess one could change those in TwinCat3, but I'm concerned to brick something.

ok, seems that your el2004 is from the "stoneage"
I just add different hardware revs to twincat and the very old ones are listed with the 3001 offset , and since rev10 the pdo seems to be 7000.
