PM5000 Modbus register for energy data

[Stuart_Cheng]

Hi All,

I noticed there are two types of energy data for PM5000: one is FLOAT32 with the unit of kWh, and the other one is INT64 with the unit of Wh.

Wondering about the reason for creating two different registers for the same data and also would like to know if they have the same roll-over value? Thanks

Hi @Stuart_Cheng 

Energy values are provided in different formats like INT64 and Float32 to accommodate various requirements. INT64 is used for precise integer representation of energy values, while Float32 is used for representing energy values with decimal points, offering a trade-off between precision and storage space. This allows for flexibility in handling energy data based on different needs and system capabilities.

As stated in user guide, when any one of the energy parameter(delivered or received) exceeds 9.2233 E(9.2233 × 10¹⁸), all the energy parameters reset to 0.
