Buildings.Controls.OBC.CDL.Discrete.Examples.DayType
Example model for the source that outputs the type of the day
Information
This example generates signals for three different work weeks.
The instance dayTypMon outputs a signal with five working
days, followed by two non-working days.
The instance dayTypSat does the same, except that the first
days is a non-working day.
The instance dayTypTwoWeeks outputs six working days, followed
by 8 non-working days.
The instance dayTypMonThr is configured the same as
dayTypMon, except that it outputs the type of the day
for three days, starting with the current day, then the next day and
the day after.
