SLc 5/02 & 1746HSCE Module

Hi, I have just read some of the posts regarding the above counter module, and although I have programmed plc's over a number of years, all be it pretty basic stuff, I think I am setting myself up for a fall. On site there is a SLC 5/02 plc (1996), with spare slots. I am using RS logix 500 V5.20 software. I know its a bit old but it works. I have been asked to add the 1746HSCE card and connect an AB 845 diff encoder. This is to measure the distance between products coming down the line. The current system is inaccurate. All I want to do is measure a number of pulses, send an internal flag to initiate an output, then reset and start all over again. This may sound pretty simple stuff to you guys, but hey we all live and learn. I would be grateful if someone could put together a ladder that would do the above, and include any other set up information that I may need. Any help is gratefully received. Regards, mrbj
