Posted 19 Feb 2006 New to plc programing. Wondering if anyone knew how to do pump alternation, in a lead lag dupplex pump program. I am trying to do this with a Direct Logic 06. I think i have everything but the pump alternation. Thanks for any help anyone could give me. Share this post Link to post Share on other sites
Posted 20 Feb 2006 (edited) The attached file includes logic to alternate between two motors. It is logic to control one of seven simulated processes on a CD you can purchase at the mrplc.com store.
