TectTempControl (FB)

FUNCTION_BLOCK TectTempControl EXTENDS ABBLConC3

Function Block TectTempControl is the main control block of temperature control process. An InOut variable TectTempZoneData saves all relevant parameters, settings and values for one temperature zone

InOut:

Scope	Name	Type	Initial	Comment	Inherited from
Input	Enable	BOOL	FALSE	A rising edge (Enable = TRUE) starts the operation, the output Busy goes to TRUE. All other inputs are read and considered continuously. Execution will continue forever until a falling edge (Enable = FALSE) aborts the operation. During Aborting the Busy is still TRUE. Afterward all outputs are reset.	AbbLConC3
Output	Busy	BOOL	FALSE	Operation is running (while output Error is FALSE)	AbbLConC3
	Error	BOOL	FALSE	Operation is stopped with error (while output Busy is FALSE). This output is TRUE for at least one cycle or until Enable is set to FALSE. The output ErrorID gives more details about the error.	AbbLConC3
Input	PidInterval	TIME	TIME#2s0ms	2: Interval time for PID and auto tune processing. It needs to be greater than 0s.
	PwmPeriod	TIME	TIME#2s0ms	3: Pulse width modulation output period. It should not be greater than PidInterval.
	Fahrenheit	BOOL	FALSE	4: A True at the input Fahrenheit of the Function Block displays the temperature in Fahrenheit, a FALSE displays the temperature in Celsius.
	ActTempRaw	INT	1	5: Actual raw temperature value from analogous input sensor.
	RawFactor	INT	10	6: Sensor provides the ActTempRaw, this value doesn’t match to the temperature in Celsius.Hence RawFactor is necessary to scale the temperature to Celsius scale. For example: if the ActTempRaw is 200 which indicates 20 degree, then the RawFactor will be 200 / 20 = 10. Range: > 0. Note It should not be 0
	AdrZoneData	POINTER TO TectTempZoneDataType		7: Input as Pointer to TectTempZoneDataType. This variable can be connected to the output of ADR Block. An input variable TectTempZoneDataType saves all relevant parameters, settings and values for one temperature zone. All function blocks for the zone interact with each other through ZoneData variable. Note It should not be 0.
Output	ErrorID	ERROR_ID		3: Error code in case of error in the function block execution
	Warning	BOOL		4: Active warning. Operation is running with warning . This output is TRUE for at least one cycle or until Enable is set to FALSE.
	WarningID	WARNING_ID		5: Warning code of active warning
	DutyCycle	INT	0	6: PWM output DutyCycle is displayed in percentage. Positive value indicates heating, negative value indicates cooling.
	DoHeat	BOOL	FALSE	7: Pulse for heating. This variable can be connected to digital output signal.
	DoCool	BOOL	FALSE	8: Pulse for cooling. This variable can be connected to digital output signal.
	HighHigh	BOOL	FALSE	9: HighHigh alarm active. The limit value is declared in the data type tsMachineSet of TectTempZoneDataType.
	High	BOOL	FALSE	10: High alarm active. The limit value is declared in the data type tsMachineSet of TectTempZoneDataType.
	Low	BOOL	FALSE	11: Low alarm active. The limit value is declared in the data type tsMachineSet of TectTempZoneDataType.
	LowLow	BOOL	FALSE	12: LowLow alarm active. The limit value is declared in the data type tsMachineSet of TectTempZoneDataType.
