Modbus Address Description
43879 Point 1 Entry Digital Status
44223 Point 1 Entry Function Type
44224 Point 1 Entry Information Number
The "Point Entry Digital Status" reuses the DNP Binary Input 43029, 43030, ...
Some analog points are supported by the 350 relay, with compatible information number
that have been identified in the device profile.
For the other measurands, it is possible to use the EnerVista SR3 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 are available for
configuration, but if Identification Type 9 (ASDU 9) is selected, up to nine measurands can
be sent in the IEC103 slave answer. For each measurand, all metering values that the
350 supports, are available in order to be mapped. There are 3 possible configurable
ASDUS.
For example, eDataVab is the index in the Modbus Memory Map.
