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 via NFC and app when a display is present (variant 1) The configuration of the Modbus interface and other parameters is performed via buttons when a display is present (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 enabled/disabled.

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 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		Indicator whether the calibration of the sensors must be performed in the device (TRUE = calibration in device required, FALSE = calibration in FB required)
Output	xAlarm	BOOL		General fault ( TRUE = fault )
Output	xAlarmCom	BOOL		General 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 operations influenced by the input 'xUpdateActual'
