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, 
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.
