350 FEEDER PROTECTION SYSTEM – COMMUNICATIONS GUIDE
IEC 60870-5-103 SERIAL COMMUNICATION
CHAPTER 2: RS485 INTERFACE
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 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.
