86 Controlling a Street Lighting Network with the Scheduler Application
• Select the preset to be used to update the values of all the data points added to the
Scheduler that have that preset defined for them. Alternatively, you can enter a new
preset and then go back to the Scheduler: Data Points Web page and define the value
(or values) for the preset.
• Enter a valid value to be written to all the data points. To enter a value, all the data points
added to the Scheduler must have the same network variable type (e.g., SNVT_switch).
d. In the Priority box, enter a priority for the event between 0 to 255 (highest to lowest priority).
The default priority for an event in an exception schedule is five more than the priorities of
events in the daily schedule. For example, if you created an event with a priority of 255 in the
daily schedules, the events in the exception schedule will have a priority of 250. This priority
essentially locks out events with lower priorities so that they cannot update the data points
written to by this event. When the event ends, lower-priority events can update the data
points.
e. To create additional events in the one-time exception, right-click anywhere in the Time or
Value boxes, and then click Add in the shortcut menu. A new row for the event is added to
the dialog. Repeat steps a–c to specify the Time and Value of the new event in the one-time
exception.
f. Click OK to save your events and return to the Scheduler: Exception Schedules Web page
Web page. Click Cancel to delete all changes and return to the Scheduler: Exception
Schedules Web page.
7. The date on which the one-time exception is to occur is highlighted teal (or dark blue) in the
calendar.
8. Click Submit.
9. To edit the one-time exception, click the teal-highlighted date in the calendar. The Edit:
<exception name> dialog opens. This dialog lists the events that are scheduled to occur on the
selected date.
The intervals specified by the events in the one-time exception are highlighted teal, and the events
in the daily schedule are highlighted grey. When events in the one-time exception end, their
priority is reset to 255 and the schedule reverts to the regular daily schedule. This means that the
highest priority event in the applicable daily and exception schedules that was supposed to occur
prior to the event in the one-time exception is executed. If there are no such events, the next
highest-priority event will execute at its regularly scheduled time.
