Posted 19 Nov 2018 Hi group! I am struggling to figure out what I am doing with the Limit instruction (ZCP 088). I want to turn on a permissive if the compared word is between 1 and 12. Rockwell makes this so much easier!!! It looks like my "=" instruction is not correct but this is how they show it in the manual??????? Share this post Link to post Share on other sites
