Function description
General
Weekdays 1 - 7 (Monday … Sunday, XXX = Mon, Tue, Wed, Thu, Fri, Sat, Sun)
Each of the seven weekdays has two separate switching periods assigned (switching period 1, switching period 2).
Each switching period 1 is defined by adjustable data (on time 1 todXXXTimeFrom1 and off time 1 todXXXTimeTo1) defined. Each switching period 2 is defined by adjustable data (on time 2 todXXXTimeFrom2 and off time 2 todXXXTimeTo2) defined. In addition, an operating mode (xXXXMode) can be set per weekday.
If off time 1 is before on time 1, then for the evaluation off time 1 is set to the value of on time 1. If on time 2 is before off time 1, then for the evaluation on time 2 is set to the value of off time 1. If off time 2 is before on time 2, then for the evaluation off time 2 is set to the value of on time 2.
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 1: on time 1 = on time 2 = off time 1 = off time 2 = TOD#00:00
When an on period is active ( xXXXMode = TRUE ) the switching period is not active for the whole day. When an off period is active ( xXXXMode = FALSE ) the switching period is active all day.\
Special case 2: on time 1 = on time 2 = off time 1 = off time 2 = TOD#23:59
When an on period is active ( xXXXMode = TRUE ) the switching period is active all day. When an off period is active ( xXXXMode = FALSE ) the switching period is not active all day.\
Prerequisite for using the function block Clock7d2Ch
For correct operation the use of the function block TimeRead2 is required.\

Display output xActive
The display output xActive takes the state TRUE if, with enable input active (xEn = TRUE) the time on weekday XXX is within switching period 1 or switching period 2 of weekday XXX (xXXXMode = TRUE, on period). The display output xActive takes the state TRUE if, with enable input active (xEn = TRUE) the time on weekday XXX is outside switching period 1 or switching period 2 of weekday XXX (xXXXMode = FALSE, off period). In all other cases the display output xActive takes the state FALSE.

On time of the switching periods of the current weekday todActivatedFrom
This output permanently shows the on time of switching period 1 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.
Off time of the switching periods of the current weekday todActivatedTo
This output permanently shows the off time of switching period 2 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.
