SAMSUNG_INTESIS_IDU_FC04_RXXX0_RXX38 (FB)

FUNCTION_BLOCK SAMSUNG_INTESIS_IDU_FC04_RXXX0_RXX38

Short description

Acquisition of actual values - 1 from Samsung - indoor units Typical application: Central acquisition of actual values from Samsung - indoor units via the Samsung - INTESIS - gateway\

Guidelines - Software creation

The following function codes (FC) are supported: 3, 4 and 6 The following modes are supported: Modbus-RTU and Modbus-TCP The following baud rates are supported (RTU): ????? For addressing, the Modbus address notation must be used. &#xNAN;************** &#xNAN;* Functions * &#xNAN;************** In this FB the relevant actual values (registers 0 - 37) of an indoor unit are read and evaluated (FC03: addresses XXX0 - XX37). The selection of the indoor unit is made via the input 'byIUAddress' in the range 1 - 64. The actual values of an indoor unit are available in the structure element 'stIndoorUnits_ActualValues_1'. Registers 0 - 14, 16 - 17 and 20 - 38 are read. Registers 15 and 18 - 19 may only be written. Registers in the range 39 - 61 are not read because they are not required for the specific application. Measured values - calibration: unclear class \

InOut:

Scope	Name	Type	Initial	Comment
Input	xEn	BOOL	TRUE	Enable / disable communication ( TRUE = enabled )
Input	byUnitId	BYTE	0	Address of the device (interface) (1 .. 15)
Input	xUpdateActual	BOOL	FALSE	Update of actual values (on every rising edge )
Input	xResError	BOOL	FALSE	Reinitialization of the output 'eErrorCodeCom' (on each rising edge)
Input	byIUAddress	BYTE	1	Number of the indoor unit (range 1 - 64)
Inout	ModbusClient	ModbusClientBase		Client of the device
Output	stIndoorUnits_ActualValues_1	SAMSUNG_INTESIS_CURRENT_VALUES_1		Structure element with the actual values - 1 of the indoor unit
Output	xSensorOffsetInDevice	BOOL		Indicates whether the calibration of the sensors of the indoor units must be performed in the indoor unit (TRUE = calibration required in the device, FALSE = calibration required in the FB)
Output	xAlarm	BOOL	FALSE	General fault ( TRUE = fault )
Output	xAlarmCom	BOOL	FALSE	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#5s0ms	Update interval for operations influenced by the input 'xUpdateActual'
