EXAMPLE 4.4 Time Qualify Optoisolated Inputs
If an input needs to be debounced or time qualified more than the
built-in 0.25 cycle, assign the input to a SEL
OGIC control equation
variables timer.
SV8 = IN2 SELOGIC Variable SV8
The output of the timer (Relay Word bit SV8T) can then be used in
place of Relay Word bit IN1; see Example 4.2 on page 4.3.
