Hi everyone,
I have a question on the ML1100 PLC. So in my program, I would like to set an alarm for low-level liquid. Since the data I got from the sensor are not stable, I want to set a timer, such as when the level is less than 20% for continuously 5sec, it will turn on the alarm. I have a "less than" function, but I don't know which function I can use for the timer. The lung below does not work. Can anyone help and give some advice.
Thank you very much.
