Scheduler 45
The Repeat Number acts as a multiplier of the Repeat Period. They should
be read in conjunction like this: “Repeat this event every 30 minutes”.
You may have noticed a slight change in the times and strings used in the
examples above. The events used in Example1 and the final one in Example3
are used in an example file on the DVM4 that you can run with ScheduleTester
(discussed below) to see how these actually operate.
The only type of field that has not been discussed yet is a set .
Example 3:
T:1:00 D:11-28-02 R:4 P:Thursday S:November E: COMMAND 1:"Happy Thanksgiving!"1BT
A set defines a certain range of valid repeat periods. In this example, only the
Thursdays in November are eligible for this event. When a set is used in an
event, the Repeat Number takes on a different meaning. Instead of being a
multiplier of the Repeat Period,
it and the Repeat Period become an index of
the set. These three fields should be read in conjunction like this: “Repeat this
event every 4
th
Thursday in November.”
Fields in Detail
There is a summarized table in the File Format/Tutorial section that lists all the
fields for your reference. Since the Event, and event Parameter fields (E:, 1:,
2:, 3:, and 4: ) have been discussed in detail in the
Events in Detail section,
we’ll discuss the rest of the fields here.
T: Start Time
The Start Time is the hour and minute your event becomes active. For most
cases being active simply means “gets executed”. You specify it in military
time 00:00 is midnight, 23:59, 11:59pm, is last minute of the day something can
be scheduled. You can specify the word
BOOT as the field’s value. This used
to make an event get executed upon every reboot after the start time and start
day have been reached. You can also specify
sunrise or sunset . In order to take
advantage of sunrise/sunset calculations in the DVM4, you need to determine
you longitude, latitude, and timezone. These can be determined online by
typing your
zipcode into many websites. Simply do a search for longitude
latitude zip code in your favorite search engine like www.google.com to find
them out. Then enter them into the Geographic Settings in DVM4’s INI file
dvm4.ini . The DVM4 calculates the sunrise/sunset values and replaces the start
time with them.
Example:
T:13:30
