6.4 Register Map
The register map of the DHB-124 meter is presented below
Notice:
All given addresses are physical addresses. In some computer pro-
grams, logic addressing is applied, then addresses must be incre-
ased of 1.

Description
4000-4049
integer
(16 bits)
Value placed in a 16-bit register.
7000-7019
float (32 bits)
Value placed in two successive 16-bit
registers. Registers include the same
data as 32-bit register from the area 7500.
Registers are only for readout.
7200-7327
float (32 bits)
Value placed in two successive 16-bit
registers. Registers include the same
data as 32-bit register from the area 7600.
Registers can be read out and written.
7500-7509
float (32 bits) Value placed in a 32-bit register. Registers
are only for readout.
7600-7663
float (32 bits)
Value placed in a 32-bit register. Registers
can be read out and written.
6.3 Description of Applied Functions
Following functions of the MODBUS protocol have been implemented
in the DHB-1xx meter:
l
03 – Readout of n-registers.
l
06 – Write register
l
16 – Write of n-registers.
l
17 – Identification of the slave device.
