FUNCTION_BLOCK OPPERMANN_T_MOD_I_XXX

Representation

General

This is a temperature transmitter for ventilation ducts and for measurement in pipelines / containers

XXX = 50: 50mm XXX = 100: 100mm XXX = 150: 150mm XXX = 200: 200mm XXX = 250: 250mm XXX = 300: 300mm XXX = 450: 450mm

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 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 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	rTempCelsius	REAL		Temperature in XX.X degrees Celsius
Output	rTempFahrenheit	REAL		Temperature in XX.X degrees Fahrenheit
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'
