;====================================================================================== ; This is a sample PGM file. The aim is to set the recycle flowrate ; (from tank3 to tank1) to be half the feed flowrate. ;====================================================================================== ;---- Define Variables ------------------------ PageLabel "Flow" TextLabel "" Checkbox UseDefaultSetPoint* Real FeedSetPoint*("Qm","kg/s")<<1000>> Real ActualFeedRate@("Qm","kg/s") Real RecycleFlowRate@("Qm","kg/s") Real RecycleRatio{r,init(0.5),Comment("FeedSetPoint / RecycleFlowRate")} ;---Logic-------------------------------- ; Allows user to change the FeedSetPoint and RecycleRatio back to default values if (UseDefaultSetPoint) FeedSetPoint = 1000 ;kg/s RecycleRatio = 0.5 ;FeedSetPoint / RecycleFlowRate UseDefaultSetPoint = 0 endif ; Performs calculations and sets values to SysCAD ["Source1.QmReqd (kg/s)"] = FeedSetPoint ;Sets the feed rate in Feeder Source1 ActualFeedRate= ["pipe1.Qm (kg/s)"] ;Gets the flowrate from Pipe1 RecycleFlowRate = ActualFeedRate * RecycleRatio ;Calculates the recycle flowrate ["Tank3.GM.IOs.[Recycle].Flow (kg/s)"] = RecycleFlowRate ;Sets the recycle flowrate to tank 3 output $ ;END OF FILE
