Operation Description
PULSE TRAIN
Creates a pulsed FALSE / TRUE output of programmable frequency.
INPUT A enables the pulse train when TRUE, disables when FALSE. INPUT B sets the length of the on part of the pulse in
seconds (1 = 1 second). INPUT C sets the length of the off part of the pulse in seconds (1 = 1 second).
WINDOW
This function outputs TRUE when INPUT A is within a programmable range, and FALSE otherwise.
INPUT B sets the threshold of the window to be monitored. INPUT C defines the range of the window around the threshold.
When the value of INPUT A is inside the window, the window expands by 0.01 to avoid flutter on output if noisy, i.e. if INPUT
B = 5 and INPUT C = 4 then the range is 3 to 7, expanded to 2.5 to 7.5 when the value if INPUT A is inside the window.
If INPUT C is set to zero, the output will only be TRUE if INPUT A is exactly equal to INPUT B (this is fulfilled in the default
condition when inputs A, B & C are all zero)
If INPUT C is set to a negative value, its absolute value defines the window range, and the output is inverted.
