Representation
Object Usage: The Calendar object provides a
means to program annual exception-day events
such as holidays and periods requiring a change
from normal schedule operation. Repeating
holidays can be defined as either calendar-based
(specific dates) or occurrence-based (set by day of
week). Each Calendar object supports up to 8
calendar events or occurrences (Programs 1 to 8).

Configuration
Properties
Programs can be assigned to one or more of the
four digital (OFF/ON) outputs. This allows a
particular output to follow a predefined sequence
that reflects the results of multiple events or
occurrences. Programs are defined by the various
configuration properties, such as start and end
dates, times, durations, assigned outputs, etc.

The “Force Exception” inputs allow direct override
control of the associated outputs. An input of ON or
OFF is directly reflected at the associated output,
regardless of calculated conditions. A not active
(NA) input allows the associated output to be under
control of the normal Calendar object calculation.
The Calendar Enable input allows normal operation
of the object whenever its input value is NA or ON.
While the Calendar Enable input value is OFF, all
outputs remain OFF and other inputs are ignored.
