			number.
OUTPUT LOW LIMIT			OFF or number	The range outside which the displayed output will flash
				unclamped. Useful for warning operator of unusual
OUTPUT HIGH LIMIT
				condition.
	ACTION		UP	At each machine scan cycle, an integration of the input is
				added to the running total. When this total reaches or
				exceeds the preset value (assumed to be in eng. Units), the
				discrete output of the totalizer goes high and remains high
				for 1 scan cycle. The totalizer then resets and starts again.
				The value resets to either zero or the residual total (final
				total minus preset) if one exists.
			DOWN	At each machine scan cycle, an integration of the input is
				subtracted from the preset value. When this result reaches
				or goes below zero, the discrete output of the totalizer goes
				high and remains high for 1 scan cycle. The totalizer then
				resets and starts again. The value resets to either the
				preset or the residual total (preset plus final total [since final
				total is either zero or negative]) if one exists.
			DEMAND	On Demand. Same as UP, except executes only while the
				ON DEMAND INPUT discrete is ON(1). Input is ignored
				while ON DEMAND INPUT is OFF(0).
			CONTIN	Continuous. Same as UP except the total ignores the
				PRESET value and integrates “forever” (continuously).
	TIME UNITS		SEC, MIN, HOUR, DAY	Time units of the totalizer
ON DEMAND INPUT			OFF, discrete parameter, 0,	Appears for Functions as the On Demand input for the
		1		DEMAND action. Activates totalizer when ON(1).
	PRESET		OFF, analog parameter,	Up totalizer counts up to this value. Down totalizer counts
			number	down from this value.
	ZERO CUTOFF		OFF or number	Represents the least value to be accumulated in the
				totalizer. Input values below this value will be input as zero.
	RESETTABLE		YES, NO	If NO, the Totalizer is non-resettable and cannot be reset
				via the operator keypad. This setting does not affect the
				action of the reset discrete parameter.
	RESET		OFF, discrete parameter, 0,	When the RESET goes high (1) an UP action totalizer will
		1.		reset to zero, or a DOWN action totalizer will reset to the
				preset value. Use SY1 F3 to reset with the RESET or F3
				key.
