Hi @Ramasamy_N 

I noticed that the PM2000 meter provides two data types for energy data:

• Register 2700: Active Energy Delivered (Into Load) FLOATING32 - with a unit of kWh
• Register 3204: Active Energy Delivered (Into Load) INT64 - with a unit of Wh

I was wondering if both of these registers have the same maximum energy value of 9,223,372,036,854,775,807 Wh (9223 PWh)? Thank you!
