Hello,

for first you need check your actual CPU for available HSC inputs and then of course types what are supported. I recommend generally take a look at web about how to obtain speed if you have some pulses with specific values or simply with some type of parameter (flow, hammer bangs, valve moves, ...). then it can be better clear to you , I expect. I recommend in this case look at MicroWin help about HSC and you can easy see there what is required and how to define them, examples are there for sure.
