Note
MINVAL, MAXVAL, and BOUND can also be programmed in synchronized actions.
Note
Behavior if values are equal
If the values are equal
MINVAL/MAXVAL are set to this equal value. In the case of BOUND the
value of the variable to be tested is returned again.
Example
Program code Comments
DEF REAL rVar1=10.5, rVar2=33.7, rVar3, rVar4, rVar5, rValMin, rValMax, rRetVar
rValMin=MINVAL(rVar1,rVar2) ; rValMin is set to value 10.5.
rValMax=MAXVAL(rVar1,rVar2) ; rValMax is set to value 33.7.
rVar3=19.7
rRetVar=BOUND(rVar1,rVar2,rVar3) ; rVar3 is within the limits, rRetVar is set to 19.7.
rVar3=1.8
rRetVar=BOUND(rVar1,rVar2,rVar3) ; rVar3 is below the minimum limit, rRetVar is set to
10.5.
rVar3=45.2
rRetVar=BOUND(rVar1,rVar2,rVar3) ; rVar3 is above the maximum limit, rRetVar is set to
33.7.
