3.2.5. Rack 5: Line_Flt
Channel Description
1 Field output channel 1 line fault
2 Field output channel 2 line fault
40 Field output channel 40 line fault
Table 9 Rack 5: Line_Flt descriptions
The line fault input state is reported as true (logic ‘1’) for a line fault condition (open circuit, short circuit, and no
field supply voltage). The logic state is the majority voted value.
3.2.6. Rack 6: Discrep
Channel Description
1 Discrepancy status outputs 1 to 16 (output 1 is LSB)
2 Discrepancy status outputs 17 to 32 (output 17 is LSB)
3 Discrepancy status outputs 33 to 40 (output 33 is LSB)
Table 10 Rack 6: Discrepancy descriptions
Each of the words reports the discrepancy status of 16 output channels. The corresponding bit within the word is
set to ‘1’ when a discrepancy condition is detected on that output channel’s output state (rack 2).
