CONSUMPTION DATA INITIALIZATION AFTER A
DOWNLOAD
It is important to keep in mind that, when reprogramming the device from ETS (either
partial or complete downloads), the consumption variables and therefore any data
accumulated so far are cleared on both partial and total registers.
If it is required to maintain the present consumption values, before carrying out the
download, the option to maintain the current values must be activated in ETS in the
desired registers, or an initial value must be parameterised (see sections 2.2.2.2 and
2.2.3.1).
There are also certain objects with the flag W enabled, so they can be initialized
directly writing the desired value in the communication object.
Notes
:
In single-phase configuration, only the energy registers broken down by each
phase can be initialized by parameter, not the global registers
.
Reactive energy registers can only be initialized by writing in the
communication object. It is recommended to initialize them after the first start-
up as they may have invalid values.
Table 2 shows the available options to set the initial value in each energy register. The
options are:
By parameter.
By object: writing the desired value in the corresponding communication
object.
Reset register: partial registers can be reset (set to zero) through the reset
communication object.
