Option Name
Description
0
Input 1 accumulate Selects Rate or Accum input of IN_1.
1
Input 2 accumulate Selects Rate or Accum input of IN_2.
2
Flow forward
Integrates forward flow (interprets reverse flow as zero).*
3
Flow reverse
Integrates reverse flow (interprets forward flow as zero).*
4
Use uncertain
Uses an input value of IN_1 or IN_2 whose status is “Uncertain”
regarding it as a value of “Good.”
5
Use bad
Uses an input value of IN_1 or IN_2 whose status is “Bad”
regarding it as a value of “Good.”
6
Carry
Carries over an excess exceeding the threshold at reset to the
next integration. (Note that this does not apply to UP_AUTO or
DN_AUTO.)
7
Add zero if bad
Interprets an increment as zero if the status of the increment is
“Bad.”
8
Confirm reset
After a reset, rejects the next reset until “Confirm” is set to
RESET_CONFIRM.
9
Generate reset
event
Generates an alert event at reset.
10~15 Reserved
* If both forward and reverse flows are enabled or disabled, both forward and reverse flows
are integrated.
30 CLOCK_PER
86400.0[sec]
AUTO Specify the period at which a periodic reset is made.
31 PRE_TRIP
100000.0
AUTO Set an allowance applied before an integrated value exceeds the setpoint.
32 N_RESET
0.0
—
Indicates the number of resets in the range of 0 to 999999.
33 PCT_INCL
0.0[%]
—
The ratio of “the integrated values of the absolute values of the increments whose
status is Good” to the “integrated values of the absolute values of the increments
irrelevant to the status” (Equation)
34
GOOD_LIM
0.0[%]
AUTO The threshold value of the ratio of “the integrated values of the increments whose
status is Good” to all integrated values in which the status of OUT is “Good”
35 UNCERT_LIM
0.0[%]
AUTO
The threshold value of the ratio of “the integrated values of the increments
whose status is Good” to all the integrated values in which the status of OUT is
“Uncertain”
36 OP_CMD_INT
0
AUTO Operator command that resets integrated values
37
OUTAGE_LIM
0.0
AUTO Maximum time for which values can be retained in the event of power failure.
It does not effect the block operation.
38 RESET_
CONFIRM
0
AUTO
Reset confirmation input, which is enabled when the Confirm reset option of
INTEG_OPTS is chosen
