Hi,
I use cpu 313C with continuous counting. I want to detect last position when sw off. for example want to read cut size. I have installed encoder on one feed roller and other blade roller have proxy sensor for end blade cut. I know feed length can be measure by encoder pluses x diameter of roller x Pi. if i control SW with proxy sensor in ob40 but i can not find quorate no. of pulse after every cut. I try to use proxy sensor as HW gate control but result is same. Any one please help me.
