Re: Programming Omron CQM1H. I need to activate an output (for 10 seconds) upon either of the following: PLC startup, of if no input buttons are pressed for 6 hours. For the startup, my first thought is to use the "always on" work bit for a timer, but for the "6 hours inactive" one, the Omron timer is max. 999.9 seconds (16.7 minutes) I guess I can have timer after timer with one timer as the input for each sequential timer, but that seems rather cumbersome and sloppy. Any advice would be appreciated. Also - the 10 second output is for a "pre-charge" valve to counteract pneaumatic cylinder leak-down to avoid "fast-starting" cylinders after leak-down. Thanks for taking the time to respond!!!!!!!!!!!!!!
