A2.5.2 Determining the Output Value
The value of OUT.Value is determined as follows:
z For counting up
 OUT=Integrationstartvalue(0)+Total
z 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 the MAN mode
after the mode was returned to AUTO.
The values in OUT_TRIP and OUT_PTRIP are determined in accordance with the correlation
between OUT and TOTAL_SP/PRE_TRIP.

For counting up, the OUT value is as follows:
z OUT<TOTAL_SP-PRE_TRIP
 =>OUT_TRIP=0,OUT_PTRIP=0
z TOTAL_SP-PRE_TRIP<=OUT<TOTAL_SP
 =>OUT_TRIP=0,OUT_PTRIP=1
z TOTAL_SP<=OUT
 =>OUT_TRIP=1,OUT_PTRIP=1
For counting down, the OUT value is as follows:
z PRE_TRIP<OUT
 =>OUT_TRIP=0,OUT_PTRIP=0
z 0<OUT<=PRE_TRIP
 =>OUT_TRIP=0,OUT_PTRIP=1
