AC500 Modbus Registers

I have modbus addresses ( %MX0.2019.3 && %MD0.17 ). I have found the decimal equivalent values for these registers, due to an answer from a previous question.
%MX0.2019.3= modbus address DEC 16155 2019*8 + 3 = 16155

%MD0.17 occupies two modbus addresses DEC 34 and DEC 35
17*2 = 34 and next one

Thank you this was very helpful. I know standard modbus AI: %IW (analog input 30001 -39999)
DI: %IX (discrete inputs 10001-19999)
DO: %QX (discrete out 1-9999)
AO: %QW (analog out 40001 - 49999)
I am looking for the holding registers and such for the AC500. Is there a map leading to decimal value. If %MD0.3 is in DEC 6 and 7. Does that mean it's under the DO(coil section)
