Скачать или смотреть Understanding TON, TOF, and RTO Timers in PLC Programming: Detailed Guide for Beginners.

Timers in PLC programming are essential for controlling outputs after a set period. There are three main types: TON (On Delay Timer), TOF (Off Delay Timer), and RTO (Retentive Timer On). Each timer has parameters like the preset time (PRE), which defines the delay, and the accumulator (ACC), which tracks the elapsed time.

TON Timer delays the start of an output until a preset time is reached, useful for processes like starting a conveyor.

TOF Timer keeps the output on until the input turns off and a delay is reached, then the output turns off.

RTO Timer retains its elapsed time even when paused and resumes from where it left off when restarted.
These timers are critical in automating machines and can be combined for more complex tasks. Thanks for watching, and see you in the next video!
