Abby Posted July 8, 2022 Report Share Posted July 8, 2022 Hello, I need to make a program in Visilogic that based on repeating 15 minute timer. when the 15 minutes is completed the ph. value will be read and if its above 10.5ph it will decrease a valve turn by 1%. If its between 10.5-8.5 it does nothing. If its below 8.5ph it will increase the valve turn by 1%. After this the timer restarts. I am having a lot of trouble with the timer and I thought of using greater thans, within range and less thans. but I don't think this is the best way. Any help is greatly appreciated Quote Link to comment Share on other sites More sharing options...
