Standard Modbus Implementation
A subset of the standard Modbus commands is implemented to
provide access into the data and status of the FUSION Meter.
The following Modbus commands are implemented:
Opcode 04 – Read Input Registers
This opcode returns the input registers, such as flow rate or
totalizer. All data is returned as 16 bit values with the MSB first
as required by Modbus
The following Input Registers are defined:
