### Functional description

#### General

#### Weekdays 1 - 7 (Monday … Sunday, XXX = Mon, Tue, Wed, Thu, Fri, Sat, Sun)

Each of the seven weekdays is assigned its own switching period.\
\
Each switching period is defined by configurable data (switch-on time **todXXXTimeFrom** and switch-off time **todXXXTimeTo**) is defined.\
In addition, an operating mode (**xXXXMode**) can be set for each weekday.\
\
If the switch-off time is before the switch-on time, then for the check the switch-off time is set to the value of the switch-on time.\
\
A switching period is active if the current time on weekday XXX is within the switching period of weekday XXX (**xXXXMode** = TRUE).\
A switching period is active if the current time on weekday XXX is outside the switching period of weekday XXX (**xXXXMode** = FALSE).

> **Special case 1: switch-on time = switch-off time = TOD#00:00**
>
> With active on period ( **xXXXMode** = TRUE ) the switching period is not active all day.\
> With active off period ( **xXXXMode** = FALSE ) the switching period is active all day.
>
> **Special case 2: switch-on time = switch-off time = TOD#23:59**
>
> With active on period (**xXXXMode** = TRUE) the switching period is active all day.\
> With active off period (**xXXXMode** = FALSE) the switching period is not active all day.
>
> **Prerequisite for the use of function block Clock7d1Ch**
>
> For correct operation, the use of the TimeRead2 function block is required.

#### Enable input *xEn*

| *xEn* | *xActive*                                                          | *todActivatedFrom*                                            | *todActivatedTo*                                               | Note           |
| ----- | ------------------------------------------------------------------ | ------------------------------------------------------------- | -------------------------------------------------------------- | -------------- |
| FALSE | FALSE                                                              | unchanged                                                     | unchanged                                                      | FB deactivated |
| TRUE  | State depending on the weekday, the time, and the switching period | Switch-on time of the switching period of the current weekday | Switch-off time of the switching period of the current weekday | FB activated   |

#### Display output *xActive*

The display output *xActive* assumes the state TRUE if, with active enable input (*xEn* = TRUE) the time on weekday XXX lies within the switching period of weekday XXX (**xXXXMode** = TRUE, on period).\
The display output *xActive* assumes the state TRUE if, with active enable input (*xEn* = TRUE) the time on weekday XXX lies outside the switching period of weekday XXX (**xXXXMode** = FALSE, off period).\
In all other cases the display output *xActive* assumes the state FALSE.

| *xEn* | *xActive* | Switching period XXX | **xXXXMode** - XXX | Note                  |
| ----- | --------- | -------------------- | ------------------ | --------------------- |
| FALSE | FALSE     | X                    | X                  | FB deactivated        |
| TRUE  | FALSE     | FALSE                | TRUE               | On period not active  |
| TRUE  | TRUE      | TRUE                 | TRUE               | On period active      |
| TRUE  | TRUE      | FALSE                | FALSE              | Off period not active |
| TRUE  | FALSE     | TRUE                 | FALSE              | Off period active     |

#### Switch-on time of the switching period of the current weekday *todActivatedFrom*

This output permanently shows the switch-on time of the switching period of the current weekday, if the enable input (*xEn* = TRUE) is active.\
In all other situations it is not changed. In special cases 1 and 2, the value TOD#00:00 is always displayed.

#### Switch-off time of the switching period of the current weekday *todActivatedTo*

This output permanently shows the switch-off time of the switching period of the current weekday, if the enable input (*xEn* = TRUE) is active.\
In all other situations it is not changed. In special case 1, the value TOD#00:00 is always displayed; in special case 2, the value TOD#23:59 is displayed.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://support.powerio.com/hub/codesys-hvac/en/hvac-library/functionblocks/clock/clock7d1ch.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
