InOut: | Scope | Name | Type | Initial | Comment | | ----------- | ----------------------- | ---------------------------- | ---------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Input | `xEn` | `BOOL` | TRUE | Enable / disable communication (TRUE = enable) | | Input | `byUnitId` | `BYTE` | 0 | Device address | | Input | `xUpdateActual` | `BOOL` | FALSE |

Update of actual values (on every rising edge
)

| | Inout | `ModbusClient` | `ModbusClientBase` | | Client of the device | | Output | `rTemp_4s` | `REAL` | | Temperature filtered 4s in XX.X degrees Celsius | | Output | `rTemp_32s` | `REAL` | | Temperature filtered 32s in XX.X degrees Celsius | | Output | `rrH_4s` | `REAL` | | Relative humidity filtered 4s in XX.X % rH | | Output | `rrH_32s` | `REAL` | | Relative humidity filtered 32s in XX.X % rH | | Output | `rDewPoint` | `REAL` | | Dew point temperature in XX.X degrees Celsius | | Output | `rAbsH_M3` | `REAL` | | Absolute humidity in XX.X g/m3 | | Output | `rAbsH_KG` | `REAL` | | Absolute humidity in XX.X g/kg | | Output | `rEnthalpy` | `REAL` | | Enthalpy in XX.X kJ/kg | | 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` | FALSE | Collective fault (TRUE = fault) | | Output | `xAlarmCom` | `BOOL` | FALSE | Collective fault - communication (TRUE = fault) | | Output | `eErrorCodeCom` | ModbusErrorCode | | Error code - communication (0 = no error) | | Output | `eErrorCodeDev` | SPLUSS\_ERROR\_CODE\_TYPE\_1 | | Error code - device (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

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://support.powerio.com/hub/codesys-hvac/en/hvac-modbus-library/functionblocks/spluss/spluss_aftf_mod.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
