Timer: Timer is mainly used to keep an output ON for a specific length of time. It provides a preset delay to the control actions. In a timer, the output will be energized when the preset value becomes equal to the accumulated value. Three different types of timers include Delay-OFF timer, Delay-ON timer and Delay-ON-Retentive timer. Timer On Delay (TON): TON refers to an on-delay timer. The on-delay timer is the most commonly used timer. TON counts the time-based intervals as soon as the instruction becomes true. Here, the output changes its state from low to high when the timer provides time delay (instruction goes from OFF to ON state).
