Representation

General

This is a pressure transmitter for measurement in pipes and tanks (0.0 - 16.0 bar overpressure)

The configuration of the Modbus interface and other parameters is performed with an available display via NFC and app ( variant 1 ) The configuration of the Modbus interface and other parameters is performed with an available display via keys ( variant 2 )

The measurement value offset can be set in 10 steps via a rotary switch on the device. A terminating resistor (120 ohm) can be activated/deactivated.

The Modbus interface is parameterized as follows without further settings:

RTU 9600 baud 8 data bits even parity 1 stop bit device address = 1

InOut:

Scope	Name	Type	Initial	Comment
Input	xEn	BOOL	TRUE	Enable / disable of communication ( TRUE = enabled )
Input	byUnitId	BYTE	0	Device address ( 1 .. 127 )
Input	xUpdateActual	BOOL	FALSE	Update of actual values ( on each rising edge ) ( range: operation )
Input	xResError	BOOL	FALSE	Reinitialization of the output 'eErrorCodeCom' ( on each rising edge )
Inout	ModbusClient	ModbusClientBase		Client of the device
Output	rPressure	REAL		Differential pressure in XX.XX bar
Output	xSensorOffsetInDevice	BOOL		Indicates whether the sensor calibration must be performed in the device ( TRUE = calibration required in device, FALSE = calibration required in FB )
Output	xAlarm	BOOL		Collective fault ( TRUE = Fault )
Output	xAlarmCom	BOOL		Collective fault - communication ( TRUE = Fault )
Output	eErrorCodeCom	ModbusErrorCode		Error code - communication ( 0 = no error )
Output	xBusy	BOOL		Communication indicator ( TRUE = Communication )
Input Const	tTimeUpdateActual	TIME	TIME#3s0ms	Update interval for the operations influenced by the input ‘xUpdateActual’
