<Appendix 2. Integrator (IT) Block>
A2-6
IM 01S01C01-01EN
OUT.Value, OUT_TRIP.Status, and OUT_PTRIP.Status are determined by the ratio of the "Good" integrated
values to all integrated values, which is stored in PCT_INCL (0% to 100%). The user must set the threshold
value of each status to UNCERT_LIM and GOOD_LIM.
The Integrator block determines the status of the output using the three parameters: PCT_INCL,
UNCERT_LIM, and GOOD_LIM.
PCT_INCL GOOD_LIM
Good
UNCERT_LIM PCT_INCL < GOOD_LIM
Uncertain
PCT_INCL < UNCERT_LIM
Bad
If INTEG_TYPE is 5, 6, or 7, the status of the trip output becomes "Good-NS-Constant."
A2.5.2 Determining the Output Value
The value of OUT.Value is determined as follows:
For counting up
OUT = integration start value (0) + Total
For counting down
OUT = integration start value (TOTAL_SP) _ Total
Total: Total of integrated values. This value is retained even if INTEG_TYPE is changed during integration
(in AUTO).
If OUT is rewritten in the MAN mode, integration starts with the value rewritten in MAN mode after the mode
was returned to AUTO.
The values in OUT_TRIP and OUT_PTRIP are determined according to the correlation between OUT and
TOTAL_SP/PRE_TRIP.
