Function
• If the current time is between the start time and end time AND the Active input = 1 (true):
o Output = 1 (true)
• Start time greater than end time:
o Output = 0 (false)
• Active input = 0 (false):
o The output remains unchanged.
• Active input = 1 (true):
o The output is recalculated and updated accordingly.
• Whole time input = 1 (true) AND Active input = 1 (true):
o Output = 1 (true)
o The element reacts as if the start time and end time were both 00:00.
Whenever a telegram is received the output starts a recalculation independently if the value has changed.
Exception handling and startup behavior

• The system time is invalid.
• Start time or end time have invalid or no values.
Note
The function element only works with start and end time. The weekdays contained in the DPT are
ignored.
