Echelon LonPoint Application and Plug-In - Manual (Page 108)

10-6 Scheduler Interface
The first step is to create a text description of the sequence of operations for the
supervisory application design. This description should be stored in your
LonMaker drawing using a Visio text box. Steps 2 and 3 are completed within
your LonMaker drawing using shapes from the Schedule stencil. You will
manually transfer the schedule design that you create in these steps to the
LonPoint Schedule Maker utility in steps 4 through 6. You will then simulate
and download the design using the LonPoint Schedule Maker utility in steps 7
and 8, and test the design on an SCH-10 module in step 9. Steps 2 through 9 are
described in more detail in the following sections.
Creating an Event Schedule Design
The event schedule design defines events based on time of day for a day of the
week or a specified date. Schedules are defined as daily schedules that specify
events for a 24-hour period, starting at midnight. Multiple daily schedules may
be defined, each with a unique name. In the following examples, schedule
names start with an sch prefix, so example schedule names are schOccupied and
schUnoccupied. A default schedule may be assigned to each day of the week,
and override schedules can be assigned to any range of dates.
To design an event schedule, follow these steps:
1. Define a daily schedule for each different set of events that occur over a 24-
hour period.
2. Assign daily default schedules for each day of the week.
3. Assign override schedules for each range of dates that require a schedule
other than the default daily schedule.
These steps are described in the following sections.
Defining Daily Schedules
A daily schedule defines times for On and Off events over a 24-hour period
starting from midnight and continuing until 11:59PM. Up to 32 events may be
defined for each daily schedule. Each event has a name. In the following
examples, these names start with an evt prefix, so example events are
evtOccupied On at 8:00 AM and evtOccupied Off at 7:00 PM.
To define a daily schedule, follow these steps:
1. Open the LonPoint Schedule stencil as described above.
2. Drag a Daily Schedule shape from the Schedule stencil to your LonMaker
drawing.
3. Click the box to the right of the Schedule Name label. If the box is not
selected, click it again.
4. Fill in a name for this daily schedule. Example schedule names are
schOccupied and schUnoccupied.
5. For each event that will occur in the 24-hour period, fill in an event name,
On or Off value, and time in the schedule.
