7 s32 IN -1 hm2_7i92.0.encoder.timer-number
What LinuxCNC version are you running?
I am running 2.8.1-44

Pin List for encoders:

what does:
mesaflash --device 7i92 --addr 10.10.10.10 -- readhmid
report?

No, adding DPLL retiming will make the average delay between reading the encoders and writing the analog out
slightly longer (by 50 usec in the example)
It's expected that "setp hm2_7i92.0.stepgen.timer-number 1" would cause an error if you
dont have any step generators in your configuration. This is presumably a pncconf bug.

DPLL module is there

I had been checking with master but 2.8.1 works for me
Can you check the bitfile checksum?
$ md5sum 7i92_7i77_7i74D.bit

Ill check it after supper but i got the 7i92 zip file from freeby.mesanet site. I compiled mesaflash from github and got the 7i92.zip from your site.
Maybe the zip file dont have the correct files in it? Can you send the bit and pin files?

Is it a config on the loadrt line?

But I get another error:
I use Intel J1900 fanless PC.
In BIOS I previously disablem all parameters that could make delay and also made isolcpu=2,3 that gives me very good latency (10k to 15k).
