#### Outputs

| Name   | Data type | Value range | Initial value | Function             |
| ------ | --------- | ----------- | ------------- | -------------------- |
| *rOut* | REAL      |             |               | Numeric output value |

#### Setpoints / parameters

| Name          | Data type | Value range | Initial value | Function            |
| ------------- | --------- | ----------- | ------------- | ------------------- |
| **rSetPoint** | REAL      |             | 0             | Numeric input value |

### Function description

#### General

This function block is used to pass a numeric input value **rSetPoint** and to directly transfer it to the numeric output value *rOut*.

{% hint style="warning" %}
**Behavior on power failure**

The numeric input value **rSetPoint** is stored in a power-failure-safe manner and automatically restored.

| **rValue**        | REAL      | VAR\_IN\_OUT |               | Enter numeric input value here e.g. EditReal.rSetPoint                                                           |
| **bDecimals**     | BYTE      | VAR\_INPUT   | 0             | Enter number of decimal places here e.g. 0 = XX ; 1 = XX.X ; 2 = XX.XX The display is not rounded but truncated. |
| **sUnit**         | STRING    | VAR\_INPUT   |               | Enter unit as a string format e.g. '°C' or '%'                                                                   |
| **rMinInputVisu** | REAL      | VAR\_INPUT   | -1000         | Min input that appears on the numpad and lights up red when the value is undercut. Input is then not possible.   |
| **rMaxInputVisu** | REAL      | VAR\_INPUT   | 1000          | Max input that appears on the numpad and lights up red when the value is exceeded. Input is then not possible.   |
| **sDialogTitle**  | STRING    | VAR\_INPUT   |               | Enter the title in string format e.g.: 'Input room temperature' - appears on the numpad during input.            |
| **iFieldSizeL**   | INT       | VAR\_INPUT   | 0             | Field expands by the number of entered pixels to the left. Required to display long numbers or units.            |
| **iFieldSizeR**   | INT       | VAR\_INPUT   | 0             | Field expands by the number of entered pixels to the right. Required to display long numbers or units.           |

{% hint style="info" %}
Note: VAR\_IN\_OUT interfaces must be assigned, VAR\_INPUT are optional.

# Agent Instructions
This documentation is published with GitBook. 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-library/functionblocks/setpoint/editreal.md?ask=<question>&goal=<endgoal>
```

`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.
