Functional Description¶

General¶

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

Each of the seven days of the week are assigned to a separate switching periods.

Each switching period is defined by adjustable data (todXXXTimeFrom1 Switch-on point in time and todXXXTimeTo1 Switch-off point in time ).
In addition, an operating mode ( xXXXMode) can be defined.

If the switch-off point in time is before the switch-on point in time, then the switch-off point in time is set to the value of the switch-on point in time for the test.

A switching period is active if the current time on weekday XXX is within the switching periods of weekday XXX ( **xXXXMode**= TRUE).
A switching period is active if the current time on weekday XXX is outside the switching periods of weekday XXX ( **xXXXMode**= TRUE).

Special case 1: Switch-on point in time= Switch-off point in time = TOD#00:00

If the switch-on period (xXXXMode = TRUE) is active, the switching period is inactive the whole day.

If the switch-off period (xXXXMode = FALSE) is active, the switching period is active the whole day.

Special case 1: Switch-on point in time= Switch-off point in time = TOD#23:59

If the switch-on period (xXXXMode = TRUE) is active, the switching period is active the whole day.

If the switch-off period (xXXXMode = FALSE) is active, the switching period is inactive the whole day.

Condition depending on weekday, time and switching periods

Switch-on point of time the switching period 1 of the current weekday

Switch-off point of time the switching period 2 of the current weekday

FB activated

Display output xActive¶

The xActive display output assumes the status TRUE if the time on weekday XXX when the enable input ( xEn = TRUE) is active
within the switching periods of weekday XXX (**xXXXMode**= TRUE).
The xActive display output assumes the status TRUE if the time on weekday XXX when the enable input ( xEn = TRUE) is active
outside the switching periods of weekday XXX (**xXXXMode**= FALSE).
In all other cases, the xActive display output assumes the status FALSE.

todActivatedFrom switch-on point in time of the switching periods of the current day of the week¶

This output permanently indicates the switch-on point in time of the switching period of the current day of the week, 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.

todActivatedFrom switch-off point in time of the switching periods of the current day of the week¶

This output permanently indicates the switch-off point in time of the switching period of the current day of the week, 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.
