The function returns a time integral of given variable.
The result is a real number. Expression, that consists this function must be
evaluated on a change.
Declaration
REAL %Integral(
REAL in Arg,
INT in TimeInt,
UNIVAL in CalcTrigger,
BOOL in ResetTrigger
)
Parameters
Arg
Variable, which average is to be calculated.
TimeInt
Variable time parameter [s]. (For example: if the
variable pump capacity is given in m3/hour, then the time
parameter will be hour and the interval is 3600, or it is expressed
by the system constant @HodInt).
CalcTrigger
Object, which change causes recalculation the
function. Its type is optional.
ResetTrigger
Change of the parameter into the TRUE state
causes resetting the integral.
