IO Real -100% to +100%
Pulse width from continuous off demand to continuous on demand.
ENABLE Boolean True to enable pulses
CYCLE_TIME Integer Pulse spacing in milliseconds
PULSE_MIN Integer
Minimum pulse width in milliseconds (smaller pulses are ignored)
RATIO_POSNEG Real Pulse width bias factor (1.0 = linear)
If the pulse width bias factor is 1.0, the function block will demand the following pulse output:

No pulses, no outputs
50% duty cycle close pulses
50% duty cycle open pulses
Close output on continuously
