I changed in the hal file to:
serial_port_0=200xxx
serial_port_0=300xxx
serial_port_0=20xxx
serial_port_0=30xxx
And the same error keeps popping up

Also the same error. As if there were no analog inputs.

Do you have field power?

The symptoms suggest you have no field power (Orange connector)
or there is some other issue with the field I/O section
(maybe W12 right or W1 right)

You are genius.
Brand new power supply defective.
Only after checking with a meter it turned out that there is no 24V.
Thank you
It remains to deal with the modbus because some error pops up and the machine will work

@PCW: This is slightly off-topic but I wanted you to know that I believe there's an error in the 7i77 manual, on page 17, there:

ANALOG INPUTS
All field input pins are capable of reading the input voltage. These are not highly accurate or high resolution but can be useful for things like potentiometer inputs. Input resolution is 8 bits and input full scale value is 36.3V. Accuracy is +-5%. Software process data modes 1 and 2 allow reading the analog voltage on inputs 0 through 3, in addition to the 32 digital bit inputs.

I believe the text in bold should read:

"Software process data modes 1,2 and 3 allow reading the analog voltage on inputs 0 through 3"

Yes, that's a mistake. I'll fix it.
