Posted 24 Jan 2013 I have a project where I am using a small prox to count the teeth on a 64 tooth gear. My problem is i don't know how to set this up so I get RPM out of it. I do have the users manual, I still couldn't figure out how to get RPM. My processor is a Compactlogix L36ERM. Any Help would be great. J.Stalman Share this post Link to post Share on other sites
