Logic thresholds are adjustable. See I/O parameter settings in Application and Controller Setup menus.

The ability to measure duty cycles near 0% or 100% is a function of the voltage/frequency of the applied signal and the input
capacitance that is added for protection against ESD. Lower input frequencies can allow reading closer to 0%/100% duty cycles.
Test each application in its actual operating environment and implement with an acceptable margin of error.
