HR=Holding Registers. So if you wanted to read the value from address 40001 (Which is the first address of the Holding Registers) you would want this HR1
4051(I’ve only ever seen 5 digit or 6 digit Modbus so I’m assuming you mean 40051) should look like this HR51, but if you do actually mean Modbus address 44051 then it would look like this HR4051
I don’t think you understand. I know its HRBCD_32. My question for my holding register 10 example would it be HRBCD_3210? Or HRBCD_32.10? Or even HRBCD_32_10?
