Creating 4 sub-categories

Table 10 shows how four sub-categories can be created by reserving the FAIL and

the DISABLE input status signals (binary weight 40 hex and 20 hex) for the

selector. Up to 4 status messages can be defined for each sub-category, with the

VOTE and RECEIVE input status signals selecting between the status messages

in each sub-category.

Table 10 - 4 Sub-categories / 4 States Each

Note: In Table 10, 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.
