78 Controlling a Street Lighting Network with the Scheduler Application
6. If the event is to occur sometime before or after sunrise or sundown, enter that period of time in
the Offset box. To schedule an event to occur before sunrise or sundown, enter a negative value;
to schedule an event to occur after these times, enter a positive value. For example, if you want a
ON event to occur 30 minutes after sundown, enter 00:30. If you want a DIMMING event to
occur 15 minutes before sunrise, enter -00:15.
7. In the Value box, enter the preset to be used to update, at the specified time, the values of all the
data points added to the Event Scheduler that have that preset defined for them. Alternatively, you
can enter a new preset or enter the value to be written to all the data points. If you enter a new
preset, you will need to go back to the Scheduler: Configure Web page and follow the steps in
Selecting Data Points to create and define the value (or values) for the preset. If you enter a value,
all the data points added to the Event Scheduler must have the same type (e.g., SNVT_switch).
8. In the Priority box, enter a priority for the event between 0 to 255 (highest to lowest priority).
This priority essentially locks out events with lower priorities so that they cannot update the data
points written to by this event. Once the Scheduler executes the event, the data points can only be
updated by an event that has an equal or higher priority. To enable lower priority events to update
the data points, you can schedule an #UNLOCK event after this event. See the next section,
Demonstrating a Street Lighting Schedule, to see how #UNLOCK events affect the Event
Scheduler.
9. Click Close.
10. Repeat steps 3–9 to schedule all the events to be executed in the exception schedule. Note that to
create additional events within a given hour, you can only right-click the Time column and click
Add Event to open the Add Event dialog. You can only create one event per minute; you cannot
create two events in an exception schedule that occur at the same time.
