A2.5 Output Process
There are the following three output parameters:
1. OUT
2. OUT_TRIP
3. OUT_PTRIP
Parameters OUT_TRIP and OUT_PTRIP are used only when INTEG_TYPE is a value from 1 to 4.
A2.5.1 Status Determination
The same criteria for determining the status of the output of the Integrator block are used in common for the
above three parameters.
0% UNCERT_LIM GOOD_LIM 100%
PCT_INCL
GOOD Uncertain Bad
PCT_INCL=100×(1 - (msp of RTotal)/(msp of ATotal))
msp of RTotal: RTotal value that is converted into a short floating-point number
msp of ATotal: ATotal value that is converted into a short floating-point number
RTotal: Integrated value of the absolute values of the increments whose status is bad
ATotal: Integrated value of the absolute values of the increments regardless of the output status
