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 specified 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 Specifies 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 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.

Reserved
* If both forward and reverse flows are enabled or disabled, both forward
and reverse flows are integrated.

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".

1
Operator command that resets integrated values.
37

4 Maximum time for which values can be retained in the event of power
failure.
It does not effect the block operation.
