The protection relay saves the 128 latest captured fault records internally. On demand, these (older) records can be read by the DNP3 controlling station.
A freely selectable part of the “Record” objects can be added to the DNP3 analog input data memory map. These objects are as default defined as ‘Static only’. This means that they can only be read on demand by the controlling station. Also notice the analog output object from the same logical node named FLTRFRC1.SelRow.ctlVal ‘-Select record’. This object should be added to the DNP3 analog output area.
The stored fault records are internally saved in indexes numbered 1...128. When the controlling station writes a value 1...128 to the “Select record” object, the entire set of fault record values belonging to that record is copied to the “Recorded” fault record DNP3 AI values. Thereafter, the controlling station can read the fault record values.
