REGISTER FORMATS
The DCOM documentation uses Modbus Register Offset numbering for all registers. A register is specified by the function type (Holding or Input) and the Register Offset. The register offset is a value between 0 and 65535.
To use the alternative Modicon register addressing mode 3xxxx and 4xxxx it is necessary to perform a conversion. The
Modicon Base Holding register is 40001, and the Modicon Base Input register is 30001. To convert DCOM registers to Modicon format, add the DCOM Register Offset to the Modicon Base Register.
examples:
DCOM Holding Register 1 = 40001 + 1
= Modicon Register 40002
DCOM Input Register 20 = 30001 + 20
= Modicon Register 30021
This conversion is only supported for Modbus register offsets upto 9999. All DCOM application registers are below this
offset.
