simply passes all input transitions through to the output(s). Thus, you would need

some elaborate logic to reset the Delay each time a button was pressed. Second, the

Delay symbol is a single-precision symbol, meaning that the values of the ‘time’

parameters can only range from 0 to 583 seconds. This makes it impossible to create

a 3-hour wait time.

Earlier in this chapter we saw an example using Buffer symbols that allowed us to

generate multiple events from a single signal. This example provided an easy and

elegant way to create system power on/off events. One limitation of that first

example was that we had no control over when each event occurred. That is, once the

input to the Buffer was triggered, all of the outputs triggered immediately, and this is

not always acceptable. For example, during a ‘power on’ sequence you want the

projector lift to lower first, then turn on the projector, then switch to a certain source

only after the projector had ample time to turn on. The figure shows how to program

such a sequence using a Delay and a Buffer. Note that the Delay outputs are passed

through the Buffer in order to trigger the desired event. This is done so that the signal

names may be driven by other system inputs or other Buffers, as described in that

first example. Finally, notice that the signal ‘system_power_off’ is routed into the

‘reset’ input of the Delay symbol. This will prevent problems when the system on

and off buttons are pressed within a few seconds of one another (because the user

changed his mind, for example). Without resetting the Delay, a ‘system on’ function

that had yet to be processed would occur during the ‘system off’ process, causing an

undesirable situation.

Oscillator Symbol

An Oscillator symbol allows you to create a constantly alternating signal, useful for

tasks such as polling an RS-232 device for status information or blinking a feedback

indicator on a user interface. The output will only oscillate for as long as the ‘gate’

input is high, thus allowing you to turn the symbol on or off. The time that the output

signal is high and low is governed by the ‘hi_time’ and ‘lo_time’ parameters.
