Property Description
The data points that will be updated by the Event Scheduler are
defined by a list of elements in the parameter.
For each element, you must enter the name
(UCPTpointName) of the data point to be updated. In addition,
you should fill in the delay time (SCPTdelayTime) property for
each data point. This integer value represents the period of time,
in seconds, that must elapse before this data point is updated
based on a DayBased or DateBased schedule point. This allows
you to stagger the updating of your data points, which may be
advisable if an Event Scheduler scheduler is to update multiple
data points at the same time.
NOTE: If a SNVT_tod_event data point is used, it will only be
updated if its value (current_state of next_state) has changed. If a
heartbeat (UNVTminSendTime) is defined for the
SNVT_tod_event data point, the time_to_next_state will be
decreased with every heartbeat.
Each Event Scheduler can have up to seven day-based schedules.
These are schedules that operate based on the current day of the
week. This may be useful when setting up a schedule that requires
different update times for different days of the week, e.g.
weekends and weekdays.
The day-based schedules for your Event Scheduler are defined by
a list of elements. For a detailed description of how to
configure each element, see Creating a Day-Based
Schedule on page 10-9.
Each Event Scheduler can have one date-based schedule. You will
reference the schedule exceptions created with the Event Calendar
application to create this date-based schedule.
The element defines the date-based schedule. For a
detailed description of how to configure the properties and
elements that define the element, see Creating a
Date-Based Schedule on page 10-11.
