The indications for common start BFI_3P, and phase-wise starts BFI_A, BFI_B and
BFI_C and neutral STN and common directional forward FW and reverse REV are all
available as outputs on the trip function.
All start and directional outputs are mapped to the IEC 61850 logical node data model
of the trip function. The time stamping is updated each time a trip or pickup signal is
changed:
• The common CND output (general) is mapped as:
dirGeneral
0 unknown
1 forward
2 backward (reverse)
3 both
• The phase wise directional outputs (DIR_A, DIR_B, DIR_C and DIR_N) are
mapped as:
dirPhsA, dirPhsB, dirPhsC, dirNeut
0 unknown
1 forward
2 backward (reverse)
