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 carried out via NFC and app when a display is present (variant 1). The configuration of the Modbus interface and other parameters is carried out via buttons when a display is present (variant 2).

The measurement value offset can be set in 10 steps using a rotary switch on the device. A termination 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 every rising edge ) (range: operation)
Input	xResError	BOOL	FALSE	Reinitialization of the output ‘eErrorCodeCom’ ( on every rising edge )
Inout	ModbusClient	ModbusClientBase		Client of the device
Output	rPressure	REAL		Differential pressure in XX.XX bar
Output	xSensorOffsetInDevice	BOOL		Indicates whether sensor calibration must be performed in the device ( TRUE = calibration required in the device, FALSE = calibration required in the 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 affected by the input 'xUpdateActual'
