I have used many of the Micros with encoder applications.
I have found that using the "HSC_Mode0" User Defined Function Block available from the Rockwell site has made it very simple to count pulses and reset that count on the fly.

I too struggled with the HSC instructions and always getting faults for configuration and such. The Mode0 instruction only has 5 input parameters and its easy. No configuration like some of the other HSC instructions.

You can also have multiple Mode0 Instructions looking at one high speed input. The first one gets HSC_ID = 0 and the second HSC_ID = 1.

Just a thought!
