Phonetics 5100, 5000 manual First program fragment uses a While loop for the timing

Sensaphone® ISACC Instruction Manual

The first program fragment uses a WHILE loop for the timing.

if (input(1)==0) { output(9,1); start_time=minutes;

while ((start_time+1)>minutes) {

}

output(9,0);

}

if (input(2)==0) { data (0,0,1,1);

}

In this code fragment, when input 1 closes, the program will turn output 9 on, and then wait for 60 seconds without doing anything else. Input 2 may close during this time period, and critical data may be lost. After this time period, output 9 is turned off, and then input 2 is checked.

The next program fragment is a 'straight-through' approach using only IF statements.

if (input(1)==0) { output(9,1); start_time=minutes;

}

if ((start_time+1)<=minutes) { output(9,0);

}

if (input(2)==0) { data(0,0,1,1);

}

In this code fragment, when input 1 closes, the program will turn output 9 on, and then continue with the rest of the program. It will then check for the output 9 off condition (time expired) and for the input 2 closure condition. It will not be held up in a WHILE loop. Please note that these examples are greatly simplified for this discussion, they do not account for the minutes variable rolling over from 59 to 0.
