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 two separate switching periods (Switching period 1, Switching period 2).

Each switching period 1 is defined by adjustable data (todXXXTimeFrom1 Switch-on point in time 1 and todXXXTimeTo1 Switch-off point in time 1).
Each switching period 2 is defined by adjustable data (todXXXTimeFrom2 Switch-on point in time 2 and todXXXTimeTo2 Switch-off point in time 2).
In addition, an operating mode ( xXXXMode) can be defined.

If the switch-off point in time 1 is before the switch-on point in time 1, the switch-off point in time 1 is set to the value of the switch-on point in time 1 for the check.
If the switch-on point in time 2 is before the switch-off point in time 1, the switch-on point in time 2 is set to the value of the switch-off point in time 1 for the check.
If the switch-off point in time 2 is before the switch-on point in time 2, the switch-off point in time 2 is set to the value of the switch-on point in time 2 for the check.

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**= FALSE).

Special case: Switch-on point in time 1 = Switch-on point in time 2 = Switch-off point in time 1 = Switch-off point in time 2 = 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: Switch-on point in time 1 = Switch-on point in time 2 = Switch-off point in time 1 = Switch-off point in time 2 = 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.

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
lies within the switching period 1 or the switching period 2 of the weekday XXX (xXXXMode = TRUE, switch-on period).
The xActive display output assumes the status TRUE if the time on weekday XXX when the enable input ( xEn = TRUE) is active
lies outside the switching period 1 or the switching period 2 of the weekday XXX (xXXXMode = TRUE, switch-off period).
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 1 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.

todActivatedTo 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 2 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.
