Denition
1 2 3 4
26 SRTOTAL 0.0 4 Indicates the snapshot of RTOTAL just before a reset.
27 SSP 0.0 4 Indicates the snapshot of TOTAL_SP just before a reset.
28 INTEG_TYPE UP_
AUTO(1)
1 Integration Type Setting
Value Name Description
1 UP_AUTO Counts up and is automatically reset when
TOTAL_SP is reached.
2 UP_DEM Counts up and is reset as demanded.
3 DN_AUTO Counts down and is automatically reset when
"0" is reached.
4 DN_DEM Counts down and is reset as demanded.
5 PERIODIC Counts up and is reset at periods specied in
CLOCK_PER.
6 DEMAND Counts up and is reset as demanded.
7 PER&DEM Reset periodically or as demanded.
29 INTEG_OPTS 0×0004 2 Species an integration optional function.
bit 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 ow (interprets
reverse ow as zero).*
3 Flow reverse Integrates reverse ow (interprets
forward ow 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 Conrm reset After a reset, rejects the next reset until
"Conrm" is set to RESET_CONFIRM.
9 Generate reset
event
Generates an alert event at reset.
10 to
15
Reserved
* If both forward and reverse ows are enabled or disabled, both forward
and reverse ows are integrated.
30 CLOCK_PER 2.7[sec] 4
Specify the period at which a periodic reset is made.
31 PRE_TRIP 100000.0 4 Set 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" (Equation).
34 GOOD_LIM 0.0[%] 4 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[%] 4 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 1 1 Operator command that resets integrated values.
37 OUTAGE_LIM 0.0 4 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 2 2 Reset conrmation input, which is enabled when the Conrm reset option
of INTEG_OPTS is chosen
