Definition
Input source to be totalized.
The range outside which the displayed output will flash
unclamped. Useful for warning operator of unusual
condition.
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.
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.
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).
Continuous. Same as UP except the total ignores the
PRESET value and integrates "forever" (continuously).
Time units of the totalizer
Appears for Functions as the On Demand input for the
DEMAND action. Activates totalizer when ON(1).
Up totalizer counts up to this value. Down totalizer counts
down from this value.
Represents the least value to be accumulated in the
totalizer. Input values below this value will be input as zero.
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.
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.
