%IntegralR
Function
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.
