Table 4-51 Totalizer Prompts
Prompt Range/Selections Definition
INPUT SOURCE OFF, analog parameter,
number. Input source to be totalized.
OUTPUT LOW LIMIT
OUTPUT HIGH LIMIT
OFF or number The range outside which the displayed output will flash
unclamped. Useful for warning operator of unusual
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,
1 Appears for Functions as the On Demand input for the
DEMAND action. Activates totalizer when ON(1).
PRESET OFF, analog parameter,
number Up totalizer counts up to this value. Down totalizer counts
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,
1. When the RESET goes high (1) an UP action totalizer will
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.
