%Integral function

Old name

%IntegralR

Function

The function returns a time integral of a specified variable. The result is a real number. Expression, that contains 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.
