Data management
The 3 Series relay supports a fixed profile and data that is configurable using the EnerVista
3 Series Setup program.
The data that can be configured are:
•
digital states
•
measurands
•
commands.
Digital states
Digital states in the relay may be mapped using the EnerVista 3 Series Setup program. By
default, states are mapped to information numbers proposed by the standard, but the
user may delete these mappings if desired.
All the mapped information will be sent as a response to a general interrogation like ASDU
1.
For the other states, the customer can assign:
1.
Information Number <1..255>
2.
Function Type <0..255>.
This means that for each digital point 3 settings are required.
Example
:
The “Point Entry Digital Status” reuses the DNP Binary Input 43029, 43030, …
Measurands
Some analog points are supported by the 3 Series relay with compatible information
numbers that have been identified in the device profile.
For the other measurands, it is possible to use the EnerVista 3 Series 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 3
Series relay 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.
