6�3�8�6� energy closes
The Energy variables occupy 90 registers.
All other variables occupy 1 register each.
energy closes
Variable (1) Address
1 day active energy close 2BC0 - 2C19
1 day reactive energy close total 2C24 - 2C7D
Index of the sample from the close of the day (2) 2C7E
1 week active energy close 2C88 - 2CE1
1 week reactive energy close total 2CEC - 2D45
Index of the sample from the close of the week (2) 2D46
1 month active energy close 2D50-2DA9
1 month reactive energy close total 2DB4 - 2E0D
Index of the sample from the close of the month (2) 2E0E
Active energy at 1 year close 2E18 - 2E71
Total reactive energy at 1 year close 2E7C - 2ED5
Index of the sample of the following year close (2) 2ED6
(1) For these variables the function 0x04 is implemented: reading registers.
(2) The information in the index of the sample of the following year close is provided in order to know in what position
the registers are currently at, bearing in mind that this position is still empty and will be the next to be filled in when
the next close is made.
The registers have information on the energy at the moment of the close.
The close is calculated as the difference between the most recent energy value and the energy
logged in the previous period.
Note: The 90 registers must be written at once (as a group), otherwise it will respond with an
error.
6�3�9�- Deleting parameters
These parameters occupy 1 register each.
Parameters can be deleted using function 0x05: writing a relay.
