4.) Judging OUT_TRIP and OUT_PTRIP (see A2.5)
OUT_TRIP and OUT_PTRIP are judged again on the basis of the cleared integrated values.
There are three options relating to a reset:
i Conrm reset (bit 8 of INTEG_OPTS)
ii Carry (bit 6 of INTEG_OPTS)
iii Generate reset event (bit 9 of INTEG_OPTS)
i Conrm reset (bit 8 of INTEG_OPTS)
If this option is enabled, the next reset is rejected until "1" is set to RESET_CONFIRM.
ii Carry (bit 6 of INTEG_OPTS)
If this option is enabled while INTEG_TYPE is UP_AUTO or DN_AUTO, the value exceeding the threshold
at a reset will be carried into the next integration.
If INTEG_TYPE is any setting other than UP_AUTO or DN_AUTO, this option is irrelevant.
iii Generate reset event (bit 9 of INTEG_OPTS)
If this option is enabled, an alert event is generated if a reset occurs.

0 BLOCK_
HEADER
TAG:“IT” Block
Tag=O/S
Information relating to this function block, such as block tag, DD revision,
execution time
1 ST_REV 0 --- 2 2 2 2 The revision level of the set parameters associated with the Integrator
block
2 TAG_DESC Null Stores comments describing tag information.
3 STRATEGY 1 2 The strategy eld is used by a high-level system to identify the function
block.
4 ALERT_KEY 1 1 Key information used to identify the location at which an alert occurred
5 MODE_BLK 4 4 Integrator block mode. O/S, MAN, and AUTO are supported.
6 BLOCK_ERR --- 2 2 Indicates the active error conditions associated with the function block in
bit strings.
7 TOTAL_SP 1000000.0 4 4 The setpoint of an integrated value or a start value for counting down
8 OUT MAN 5 5 The block output
9 OUT_RANGE
1000000.0
11 Set scaling for output display. This does not affect operation of the function
block.
It is used for making memos.
0.0
m3(1034)
0
10 GRANT_DENY 0 2 The parameter for checking if various operations have been executed
11 STATUS_
OPTS
0 O/S 2 Allows you to select a status-related option.
The Integrator block uses "Uncertain if Man mode" only.
12 IN_1 0.0 5 5 Inputs ow (Rate, Accum) signals from the AI block or PID block.
13 IN_2 0.0 5 5
14 OUT_TRIP 0 2 2 An output parameter informing the user that the integrated value has
exceeded the setpoint
15 OUT_PTRIP 0 2 2 An output parameter informing the user that the integrated value is
reaching the setpoint
16 TIME_UNIT1 sec(1) MAN 1 Set the time unit of the rate (kg/s, lb/min, kg/h ... etc.) of the corresponding
IN.
17 TIME_UNIT2 sec(1) MAN 1
18 UNIT_CONV 1.0 4
Specify the unit conversion factor for standardizing the unit of IN_2 into
that of IN_1.
19 PULSE_VAL1 1.0 MAN 4 Set the factor for converting the number of pulses for the corresponding
IN into an appropriate engineering unit.
20 PULSE_VAL2 1.0 MAN 4
21 REV_FLOW1 0 2 2 Selector switch used to specify the uid ow direction (forward/reverse)
with respect to the corresponding IN
22 REV_FLOW2 0 2 2
23 RESET_IN 0 2 2 The parameter that receives a reset request from an external block to
reset the integrated values
24 STOTAL 0.0 4 Indicates the snapshot of OUT just before a reset.
25 RTOTAL 0.0 MAN 4 4 Indicates the integrated value of the absolute values of the increments if
the input status is "Bad."
