Logic
The input or inputs are processed by a logic operator. Call the result of this logic operation “Result”.
Result is a pulse that goes ON(1) when the logic is true, and OFF(0) when the logic is not true. Result
is then processed according to the specified condition type and condition time. The final output is a
discrete pulse CVn OS. See Figure 4-5.
