F6 – Unsigned 16-bit integer, No decimal places. Encoded Fault Trip Type. The lower and upper 16-bits of the 32-bit value
are assigned to two separate points. To read the trip type the two points need to be read and concatenated to form a 32-bit
word.
Each bit of Trip Type indicates a Trip flag that is picked up. The following table lists the mnemonic for each of the bits of Trip
Type.
F7 – Unsigned 8-bit integer, No decimal places. Encoded Trip Phase information.
Trip phases is a single byte value with the least significant four bits indicating which of the four phases have a trip fault as
shown below:
Trip Phases: xxxxGCBA (binary)
A = '1' then Phase A has a Trip Fault
B = '1' then Phase B has a Trip Fault
C = '1' then Phase C has a Trip Fault
G = '1' then Phase G has a Trip Fault
F8 – Unsigned 16-bit integer, No decimal places. Part of 48-bit DNP Time. This has the same format as the DNP Time
object (50), Variation 1, except that it has been assigned to three separate points as shown in the table. After reading the
three points they should be concatenated to form a 48-bit value and interpreted as DNP Time Object.
F9 – Unsigned 16-bit integer. No decimal places. Encoded CPU Status information.
F10 – Unsigned 16-bit integer. No decimal places. Encoded ANI Status information.
F11 – Unsigned 16-bit integer. No decimal places. Encoded DSP Status information.
F12 – Unsigned 16-bit integer. No decimal places. Encoded Miscellaneous Status information.
F13 – Unsigned 8-bit integer, No decimal places. Encoded RMS/HiZ Fault Type. There are four valid RMS/HiZ fault type
codes as give below.
