Chapter 7, Problem 8P
Program Plan Intro
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 a Delay-OFF, a Delay-ON, and a 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 some time delay (instruction goes from OFF to ON state).
