Representation

General

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

The Modbus interface and other parameters are configured via NFC and app when a display is present (variant 1). The Modbus interface and other parameters are configured 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 terminating resistor (120 Ohm) can be activated / deactivated.

The Modbus interface is parameterized as follows without any 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 = enable)
Input	byUnitId	BYTE	0	Device address (1 .. 127)
Input	xUpdateActual	BOOL	FALSE	Updating the actual values (at every rising edge ) (range: operation)
Input	xResError	BOOL	FALSE	Reinitialization of the output eErrorCodeCom (with every rising edge)
Inout	ModbusClient	ModbusClientBase		Client of the device
Output	rPressure	REAL		Differential pressure in XX.XX bar
Output	xSensorOffsetInDevice	BOOL		Indication of whether the sensors must be calibrated in the device (TRUE = calibration in the device required, FALSE = calibration in the FB required)
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 processes influenced by the input xUpdateActual influenced
