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 the input value
of IN_1 or IN_2 whose
status is “Uncertain”
regarding it as a value
of “Good”.
5
Use bad
Uses the 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 reset, rejects
the next reset until
“Confirm” is set to
RESET_CONFIRM.
9
Generate
reset event
Generates an alert
event at reset.
10 to
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]
4
Specifies the period at which a periodic reset
is made.
31 PRE_TRIP
100000.0
4
Specifies an allowance applied before an
integrated value exceeds the setpoint.
32 N_RESET
0.0
4
4
Indicates the number of resets in the range of
0 to 999999.
33 PCT_INCL
0.0[%]
4
4
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” PCT_INCL = 100 x (1−(msp of
RTotal)/msp of ATotal))
34 GOOD_LIM
0.0[%]
4
The threshold 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”
