INTEG_OPTS setting Description
Carry
Carry the excess past the trip point into the next integration cycle as
the initial value of the integration.
Add zero if bad
This option ignores Bad value at input. The input with Bad status is
not integrated.
Confirm reset
If the Confirm reset is set, the block shall not process subsequent re-
set at RESET_IN until RESET_CONFIRM discrete input is TRUE.
Input 1 pass through
This is special option only used for Emerson Integrator block to pass
internal totals to Integrator block.
TIME_UNITn: The integrator requires units per second, so TIME_UNITn is used to
convert rate units of minutes, hours and days back to seconds. Minutes divides the
input by 60, Hour by 3600, and Day by 86400 so that the result is engineering units
per second.
TPTAL_SP: The integrator may count up to TOTAL_SP or count down to zero from
TOTAL_SP, depending upon the INTEG_TYPE selection. Same units as OUT.
UNIT_CONV: Factor to convert the engineering units of input 2 into the engineering
units of input 1. It can be any positive decimal number or fraction. It defaults to 1.
PULSE_VALn: Factor to convert Inn pulses to engineering units to get a total in
engineering units.
PRE_TRIP: Adjusts the amount of IN that will set OUT_PTRIP when the integration
reaches (TOTAL_SP-PRE_TRIP) when counting up or PRE_TRIP when counting down.
Same units as OUT. It defaults to 0.
IN_1: The main input to this block, normally a rate in units per TIME_UNIT of time.
INTEG_OPTS allows the input to come from a pulse input block or another INT block,
using PULSE_VAL for scaling.
IN_2: The second input, with the same characteristics as IN_1. This input allows for
totalizing the difference between (net) of two flows.
RESET_IN: Momentary discrete input that resets the totalizers, if permitted. May not
work if the type is PERIODIC.
RESET_CONFIRM: Momentary discrete input that enables the next Reset command,
if the Confirm option is set.
OUT: The output that contains the value of the total register and a calculated status.
OUT_PTRIP: The pre-trip discrete output.
OUT_TRIP: The trip discrete output.
PCT_INCL: Indicates the percentage of inputs with Good status compared to a total
for all inputs.
RTOTAL: Indicates the total of the absolute value of input values with Bad or
Uncertain status, as chosen by INTEG_OPTS. Same units as OUT.
STOTAL: The read-only snapshot of TOTAL just before a reset. Same units as OUT.
