Measurands:
The standard proposes some analog points supported by the F650 with compatible information number that has been
included in the previous profile.
For the other measurands, it would be possible to use the 650 EnerVista Setup to select the desired point and assign the
Identification Type (3 or 9), Function Type <0..255>, and Information Number <1..255>.
If the user selects Identification Type 3 (ASDU 3) only four measurands will be available for the configuration, but if
Identification Type 9 (ASDU 9) is selected, up to nine measurands could be sent in the IEC103 slave answer. For each
measurand, all metering values that F650 supports, will be available in order to be mapped.
In the measurands configuration screen, with each selected measurement, a Factor and an Offset must be configured. The
Factor is a multiplier factor and the Offset is an offset factor to be applied to the relay measurement to make the final
measurement calculation to be sent to the master The factor and offset parameters allow the user to perform different
scaling in the relay measurements. The final measurement sent to the IEC103 master will be: "a*x+b", where "x" is the relay
measurement, "a" is the multiplier factor and "b" is the offset.
The measurands will be send to the primary station as a respond to class 2 request. There is a Timeout configurable with
increments of 100 ms, between 0 and 60 min, in order to configure the interval desired.
