### Function 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 adjustable data (switch-on time **todXXXTimeFrom** and switch-off time **todXXXTimeTo**) .\
Additionally, an operating mode (**xXXXMode**) per weekday.\
\
If the switch-off time is earlier than the switch-on time, the switch-off time is set to the value of the switch-on time for evaluation.\
\
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**
>
> When on period is active ( **xXXXMode** = TRUE ) the switching period is not active all day.\
> If the off period is active ( **xXXXMode** = FALSE ) the switching period is active all day.
>
> **Special case 2: switch-on time = switch-off time = TOD#23:59**
>
> When on period is active (**xXXXMode** = TRUE) the switching period is active all day.\
> When off period is active (**xXXXMode** = FALSE) the switching period is not active all day.
>
> **Prerequisite for using the function block Clock7d1Ch**
>
> The use of the TimeRead2 function block is required for correct operation.
#### On period
#### Off period
#### Enable input *xEn*
| *xEn* | *xActive* | *todActivatedFrom* | *todActivatedTo* | Note |
| ----- | ------------------------------------------------------------ | ------------------------------------------------------------- | -------------------------------------------------------------- | ----------- |
| FALSE | FALSE | unchanged | unchanged | FB disabled |
| TRUE | State depending on weekday, time of day and 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 enabled |
#### Display output *xActive*
The display output *xActive* assumes the state TRUE if, with the enable input active (*xEn* = TRUE) the time on weekday XXX is within the switching period of weekday XXX (**xXXXMode** = TRUE, on period).\
The display output *xActive* assumes the state TRUE if, with the enable input active (*xEn* = TRUE) the time on weekday XXX is 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 disabled |
| 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 shown.
#### 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 shown, in special case 2 the value TOD#23:59 is shown.
