Hello,
I would like to ask for your help. How can I read the position on the DOP-103BQ display from the DELTA ASD-B3 driver via Modbus ASCII mode?
I don’t know which register it is and I can’t find out.
I would probably need to create a MACRO that converts the number of pulses into length.
Thank you very much for your help.
Best regards.

If you don't know the register then this is likely to be very difficult.
I found a terminal emulator that would automatically work out checksums, which allowed me to manually type modbus commands, you could try a brute-force approach to work out which registers return a non-error result, then try to work out which is position.
Unfortunately I am away from that PC at the moment and can't remember what I used. I might be able to find out tomorrow.
There may be existing software out there that will poll all register addresses looking for replies.
