PmpTankSimu (FB)

FUNCTION_BLOCK PmpTankSimu EXTENDS AbbLConC3

The function block PmpTankSimu is used to simulate the water tank.

• This simulation can be used in all the three process control modes:

  • Pressure

  • Flow

  • Level

Note

Use this function block only for simulation testing and not with critical hardware in loop.

InOut:

Scope	Name	Type	Initial	Comment
Input	Mode	INT	1	2: The input Mode selects the pumping operation mode. Range-[1 to 2] 1 = Emptying. 2 = Filling.
	TankHeight	REAL	20.0	3: The input TankHeight defines the Height of Tank in meters. Range-Value>0.0
	TankDepth	REAL	10.0	4: The input TankDepth defines Depth of tank in meters. Range-Value>0.0
	TankWidth	REAL	5.0	5: The input TankWidth defines the Width of tank in meters. Range-Value>0.0
	SetInitialLevel	BOOL	FALSE	6: The input SetInitialLevel allows to set the initial level for tank simulation. When input is TRUE, initial level setting for tank simulation is allowed. When input is FALSE, initial level setting for tank simulation is not allowed.
	InitialLevel	REAL	10.0	7: Initial value of tank level in meter. Range- [0.0 to TankHeight]
	TankOutletDiameter	REAL	0.25	8: The input TankOutletDiameter defines the Outlet diameter of pipe in meter. Range-Value>0.0
	PumpActFlow	ARRAY [1..4] OF REAL		9: The input PumpActFlow is an array of actual flow in cubic meters per hour. Range-Value>0.0 Note At the first index of array PumpActFlow[1] connect the actual flow of the pump with PumpID = 1. This pattern must be followed for all pump IDs.
Inout	TankInletFlow	REAL		10: The input TankInletFlow defines the Inlet flow into the tank in m3/sec, for simplicity it is assumed that inflow is constant.
	TankOutletFlow	REAL		11: The input TankOutletFlow defines the Outlet flow into the tank in m3/sec, for simplicity it is assumed that outflow is constant.
Output	ErrorID	ERROR_ID		3: Error code.
	WaterLevel	REAL	0.0	4: The output WaterLevel indicates the Level of the tank in meter.
	WaterLevelPercent	REAL	0.0	5: The output WaterlevelPercent indicates the Level of the tank in percentage. Range-[0 to 100]
	WaterVolume	REAL	0.0	6: The output WaterVolume indicates the Actual water volume in m3.
	TankVolume	REAL	0.0	7: The output TankVolume indicates the tank volume in m3.
	TankPressurePercentage	REAL	0.0	8: Pressure in percentage at the bottom of tank. Range-[0 to 100]
	TankPressurePascal	REAL	0.0	9: The output TankPressurePascal indicates the Pressure at the tank bottom in Pascal.
	TankPressurePSI	REAL	0.0	10: The output TankPressurePSI indicates the Pressure at the tank bottom in PSI.
	OutletPressurePascal	REAL	0.0	11: The output OutletPressurePascal indicates the Pressure at the outlet pipe in Pascal.
	OutletPressurePSI	REAL	0.0	12: The output OutletPressurePSI indicates the Pressure at the outlet pipe in PSI.
