3.4.10 TOTALIZER MODULES
Eight Totalizer Modules are present in the controller. Each module provides a "totalization" (integra-
tion) of the specified input. Sampling occurs once a second whenever the input parameter contains
a legitimate datapoint specification.
INPUT:
This designates the datapoint to be totalized. It can contain any B, C or H datapoint, i.e., C100 for
totalizing CON0 PV.
SCALE FACTOR:
The value of the input is multiplied by this parameter prior to being summed to the running total.
The parameter is used for both scaling and time interval integration.
For example, if AI0 is in M gallon/day, in order to totalize in K gallon the Scale Factor (SF) would
be:
SF = Units X Time Base
Conversion Conversion
SF = 1000 K gal X 1 day X 1 hr X 1 min X 1 sec = 1000 = .01157
M gal 24 hrs 60 mins 60 sec sample 86400
ROLLOVER VALUE:
This parameter specifies the maximum value of the totalizer. When the total reaches this
value it is reset to 0.0 and continues totalizing. This must be a positive number.
DROPOUT VALUE:
When the value of the input is less than this parameter, no change in the total will occur.
RESET:
When this parameter is a "1" the total will be forced to 0.0 and the parameter returned to "0".
ACTUAL TOTAL:
This parameter indicates the integer value of the total accumulation.
OUTPUT PULSE:
This parameter is pulsed to a "1" for one scan each time the ACTUAL TOTAL reaches the ROLL-
OVER VALUE.
TAG:
This parameter allows a 10 character name to be associated with each totalizer.
ENGINEERING UNITS:
This parameter allows a 10 character word to indicate the units of measure for each totalizer.
