I would recommend using one of the built-in high speed counter inputs. Depending on the address, you can use one input for count up pulses and one for count down pulses. The book you need is JY992D88101, it's called FX PROGRAMMING MANUAL II and is a free download from www.meau.com. Look at the section about high speed counters.
