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 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).

Explanation of Solution

b.

Timer-timing bit of a timer instruction:

  • When the accumulated value of a timer changes, the timer-timing bit becomes true.
  • The accumulated value refers to the current delay of the timer.
  • The timer instruction becomes true when the control line of the timer is energized by the power s...

Explanation of Solution

c.

Done bit of a timer:

  • The accumulated value refers to the current delay of the timer.
  • The preset value refers to the delay period of the timer...
