7.2 i-meter® ModBus RTU Registers Mapping
The ModBus module has a plethora of registers that present the metering data, as well as diagnostic
information for the module itself. The bulk of the registers are available using the Read Holding Register
ModBus command, while the Read Input Registers provides direct read access to the non-volatile memory.
The system registers provide general information about the meter and the ModBus module. This
information is the identification data and it generally remains constant with the exception of the up time.
