The HSC function can execute fast counts of pulses from sensors, encoders, switches, and so on, that are connected to the dedicated fast inputs.
There are 2 types of HSC:
oSimple type: a single input counter.
oMain type: a counter that uses up to 4 inputs (2 fast inputs and 2 standard inputs) and 2 reflex outputs.
