Declaration
REAL %Integral(
   REAL in Arg, 
   INT in TimeInt, 
   UNIVAL in CalcTrigger, 
   BOOL in ResetTrigger
 )
Parameters
ArgVariable, which average is to be calculated.
TimeIntVariable 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).
CalcTriggerObject, which change causes recalculation the function. Its type is optional.
