mode: e.g.
Mode = RTU 8N2
(value 0x02 in case of readout/record
through the interface).

7200-7400
Float (32 bits)
The value is placed in two successive 16-bit
registers. Registers enclose the same data as
32-bit registers from the 7600 area.
Registers are only for readout.
7600-7700
Float (32 bits)
The value is placed in two successive 16-byte
registers. Registers enclose the same data as
32-byte registers from the 7500 area.
Registers are only for readout.
7500-7600
Float (32 bits)
The value is placed in a 32-byte register.
Registers are only for readout.
