7-12 Application Notes
Now our V16+ is fully configured for its operating environment. The next
step is to create and add events to the sequences of MYSHOW.
Configuring Sequences
We now will edit and configure our sequences by working with the
Sequences of MYSHOW window. The V16+ supports up to 256
sequences. Each sequence may be up to 32,767 events long (although our
V16+ can only hold around 8,192 total events since it supports a maximum
of 64KB of show memory), and all sequences execute independently and
simultaneously. Each sequence is started, paused, stopped and reset by its
own unique set of conditions and can interact with other sequences as well.
The logical place to begin our sequence programming is with our auto-
executed sequence, the one that is also initiated by pressing the first button
on the V16+ front panel. This is our show startup function and will bring
all of the equipment in the attraction to a known starting state whenever the
V16+ is first powered up or this first button is pushed.
Each sequence that we write must have its own setup properly filled in, in
order to behave in the way that we expect. Double-click on the name of the
Default sequence in the list and change the sequence name to “Startup”.
For each sequence we can assign dedicated start, stop, pause and reset
functions. These are normally attached to the front panel buttons on the
V16+. In the case of our Startup sequence we have no requirement for a
stop, pause or reset button. We do, however, want to attach the V16+'s first
button to start this sequence by setting the Start Trigger of Startup to
FrontPanelStart . We also want this sequence to be Autostart Enabled so
that it will start immediately at powerup.
Similarly, the sequences Startshow and EStop should be assigned start
triggers of
OCCStart
and
OCCStop
, respectively. The rest of our
sequences will be started and reset by other sequences, so they should not
be assigned any triggers.
Programming Sequences
Up to this point we have configured the V16+ environment and given
English names to its input, output and serial ports. We have also defined
some general purpose strings and given them English names. All of this
