# SAMSUNG\_INTESIS\_IDU\_FC04\_RXXX0\_RXX38 ## `SAMSUNG_INTESIS_IDU_FC04_RXXX0_RXX38` (FB) `FUNCTION_BLOCK` SAMSUNG\_INTESIS\_IDU\_FC04\_RXXX0\_RXX38 ### Short description > Capture of actual values - 1 from Samsung - indoor units > > Typical application: Central capture of actual values from Samsung - indoor units via the Samsung - INTESIS - gateway ### Representation
#### 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 transmission rates are supported (RTU): ????? The Modbus address specifications must be used for addressing. \&#xNAN;**\*\*\*\*\*\*\*\*\*\*\*\*\*\*** \&#xNAN;**\* Functions \*** \&#xNAN;**\*\*\*\*\*\*\*\*\*\*\*\*\*\*** In this function block, the relevant actual values (registers 0 - 37) of an indoor unit are captured and evaluated (FC03: addresses XXX0 - XX37). The indoor unit is selected 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` available. Registers 0 - 14, 16 - 17 and 20 - 38 are read. Registers 15 and 18 - 19 may only be written. The registers in the range 39 - 61 are not read, as they are not needed for the specific application. Measured values - matching: unclear class InOut: | Scope | Name | Type | Initial | Comment | | ----------- | ------------------------------ | ------------------------------------ | ---------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Input | `xEn` | `BOOL` | TRUE | Enable / disable communication (TRUE = enable) | | 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 (with every
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` | |

Display showing whether the matching of the sensors of the indoor units in
the indoor unit must be performed (TRUE = matching in the device
required, FALSE = matching in the FB required)

| | Output | `xAlarm` | `BOOL` | FALSE | Collective fault (TRUE = fault) | | Output | `xAlarmCom` | `BOOL` | FALSE | 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#5s0ms |

Update interval for the processes influenced by the input
xUpdateActual influenced
