Relative time

Previous chapterNext chapter Show allShow all    Hide allHide all

When executing relative times in conjunction with absolute switching points, the way a model is linked (or not) to a specific day is a decisive element. The calendar day always starts with the start of day defined for the equipment. Should the equipment's cycle extend beyond the day, any times defined prior to the start of the day are considered to belong to the previous day.

For instance: Start of day, 02:00:00 - End of day, 01:59:59. When only one user event trigger occurs on Monday 15.10.2001 at 00:30:00, the model defined for Sunday 14th shall be used. If the trigger in fact occurs around 02:00:00, the model defined for Monday shall be used.

e.g.: Start of day, 06:00:00 - End of day, 21:59:59. When only one user event trigger occurs on Monday 15.10.2001 at 00:30:00, the model defined for Monday 15th shall be used.
