InOut:

Scope	Name	Type	Initial	Comment
Input	xEn	BOOL	TRUE	Enable / disable communication ( TRUE = enabled )
Input	byUnitId	BYTE	0	Device address (1 - 99)
Input	xUpdateActual	BOOL	FALSE	Update of actual values (on every rising edge )
Input	xResError	BOOL	FALSE	Reinitialization of the outputs ‘eErrorCodeCom’ and ‘xSmokeAlarm’ to the fault-free state (on every rising edge)
Inout	ModbusClient	ModbusClientBase		Client of the device
Output	eState	OPPERMANN_STATE_CODE		Current state of the channel smoke detector (1 = normal operation)
Output	wSensor	WORD		Internal measured value of the smoke detector (< 255 = no alarm)
Output	wPollution	WORD		Current contamination level of the sensor in XXX percent
Output	xAirflow	BOOL		Current indication of the airflow (0 = no airflow)
Output	xSmokeAlarm	BOOL	FALSE	Smoke alarm - device (TRUE = alarm)
Output	xPollutionAlarm	BOOL	FALSE	Alarm - contamination > wSetpPollutionAlarm (TRUE = alarm)
Output	xAlarm	BOOL	FALSE	General fault ( TRUE = fault )
Output	xAlarmCom	BOOL	FALSE	General fault - communication ( TRUE = fault )
Output	eErrorCodeCom	ModbusErrorCode		Error code - communication ( 0 = no error )
Output	wErrorCodeDev	WORD	0	Error code - device (0 = no error)
Output	xBusy	BOOL		Communication indicator ( TRUE = communication )
Input Const	wSetpPollutionAlarm	WORD	50	Threshold - contamination level in percent
Input Const	tTimeUpdateActual	TIME	TIME#3s0ms	Update interval for operations influenced by the input 'xUpdateActual'
