Table 9 shows how two sub-categories can be created by reserving the FAIL input

be defined for each sub-category, with the VOTE, RECEIVE and DISABLE input

status signals selecting between each status message.

Table 9 - 2 Sub-categories / 8 States Each

Note: In Table 9, any bit or input status signal shown as a 1 is an active input

signal and any bit shown as a 0 is an inactive input signal. For the MCN system,

all I/O signals are active low, so any active input status signal is low at the CIB or

IOB I/O connector and any inactive input status signal is high at the CIB or IOB

I/O connector.
