Command State 94064-99014

The above diagrams represent the P/E, RNG, and PEN logic after the end of the "P1 singles" mode. The equations for P/E, RNG, and PEN events are:

Event type	Coincidence equation
P, E	P1.P2.P4*
RNG	P1.P2.P4.AL*
PEN	P1.P2.P8

The buffers into which "orderly" events can fall are as follows:

Range	No guards triggered	Low, not high guard triggered	High guard triggered
P1	NONE	NONE	NONE
P1 through P2	P/E	P/E	P/E
P1 through P3	P, E	P/E	P/E
P1 through P4, P5, P6, or P7	RNG	NONE	NONE
P1 through P8	RNG, PEN	PEN	PEN

This is the command state that PET was in through most of the mission. It is similar to the mode before the "P1 singles" period, except that the AH* term has been removed from the P and E equations.
