Scope	Name	Type	Initial	Comment
Input	xEn	BOOL	TRUE	Enable / disable communication (TRUE = enable)
Input	byUnitId	BYTE	0	Device address
Input	xUpdateActual	BOOL	FALSE	Update of actual values (on every rising edge )
Input	xUpdateSetp	BOOL	FALSE	Update of setpoints (on every rising edge )
Input	xResError	BOOL	FALSE	Reinitialization of the outputs eErrorCodeCom or stErrorCodeDev to the fault-free state (on every rising edge)
Input	rSetpPerc	REAL	0.0	Setpoint in % (0.0 - 100.0 %) depending on application
Input	eOverrideCon	BELIMO_VRU_D3_BAC_OVERRIDE_CON	BELIMO_VRU_D3_BAC_OVERRIDE_CON.NO_OVERRIDE	Airflow control: setpoint - airflow in % (0.0 - 100.0 %) (0.0 % = Vmin, 100.0 % = Vmax) Forced override of the air damper (0 = none)
Inout	ModbusClient	ModbusClientBase		Client of the device
Output	rVminM3H	REAL		Minimum value - airflow in m3/h
Output	rVmaxM3H	REAL		Maximum value - airflow in m3/h
Output	rVnomM3H	REAL		Nominal airflow in m3/h
Output	rVolFlowM3H	REAL		Actual value of the airflow in m3/h
Output	rSetpPercFb	REAL		Feedback of the setpoint in % (0.0 - 100.0 %)
Output	eCommandFb	BELIMO_VRU_D3_BAC_COMMAND		Feedback of the triggering of test functions (0 = none)
Output	eOverrideConFb	BELIMO_VRU_D3_BAC_OVERRIDE_CON		Feedback of the forced override of the air damper (0 = none)
Output	xAlarm	BOOL	FALSE	Collective fault (TRUE = fault)
Output	xAlarmCom	BOOL	FALSE	Collective fault - communication (TRUE = fault)
Output	eErrorCodeCom	ModbusErrorCode		Error code - communication (0 = no error)
Output	stErrorCodeDev	STRING		String with the numbers of the active device errors
Output	xBusy	BOOL		Communication indicator (TRUE = communication)
Input Const	eCommand	BELIMO_VRU_D3_BAC_COMMAND	BELIMO_VRU_D3_BAC_COMMAND.NO_COMMAND	Triggering of test functions (0 = none)
Input Const	xSetpVolumeFlowMinMax	BOOL	FALSE	Triggering the transfer of the parameters rSetpVolumeFlowMin or rSetpVolumeFlowMax (on every rising edge)
Input Const	rSetpVolumeFlowMax	REAL	2000.0	Setpoint for the maximum volume flow in the selected volume flow unit (at rSetpVolFlowPerc = 100.0 %)
Input Const	rSetpVolumeFlowMin	REAL	500.0	Setpoint for the minimum volume flow in the selected volume flow unit (at rSetpVolFlowPerc = 0.0 %)
Input Const	tBusFailureTimeOut	TIME	TIME#10s0ms	Duration for activation of the state Communication error (t = 0s = disabled, for t >= 10s (at least 10 s) the parameter must rSetpVolFlowPerc must be transferred cyclically with a time interval < t)
Input Const	rBusFailurePos	REAL	100.0	Position of the damper in the event of a bus failure (in %, 100% = open)
Input Const	tTimeUpdateSetp	TIME	TIME#45s0ms	Update interval for the processes influenced by the input xUpdateSetp influenced
Input Const	tTimeUpdateActual	TIME	TIME#3s0ms	Update interval for the processes influenced by the input xUpdateActual influenced
