barkergc1978 Posted June 1, 2017 Report Share Posted June 1, 2017 I am having a hard time on my first PLC project. I cannot get any of the logic to count when I push buttons. Any assistance will help. M91-2- t1, I am sure that it is wired in correctly, as all of the other outputs work. M90.U90 Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted June 1, 2017 MVP 2023 Report Share Posted June 1, 2017 I don't have an M90 handy to test your logic, but before anything else, break up your logic so that you only have 1 single network in each ladder rung. Link to comment Share on other sites More sharing options...
barkergc1978 Posted June 2, 2017 Author Report Share Posted June 2, 2017 So i need different blocks for the same output? Link to comment Share on other sites More sharing options...
Ofir Posted June 2, 2017 Report Share Posted June 2, 2017 Hi, First of all use positive transition when using the keys operands in order to get a single press. Can you specify what exactly is not working? I noticed in the logic for example for key#1 that you are activating outputs according to the screen which is loaded. (I didn't see any counters) Link to comment Share on other sites More sharing options...

You have two networks in each of ladder rungs 1, 2, 3, 8, & 9, and you have three in ladder rung 7. Link to comment Share on other sites More sharing options...
