A TOF timer starts to accumulate time when the rung:
A) makes a true to false transition.
B) makes a false to true transition.
C) when the done bit is set to 1.
D) when the done bit is reset to 0.
True To False Transition
The change of a logical signal or condition from a true (high, 1) state to a false (low, 0) state.
- Evaluate the relationship between timers and output behaviors considering the circumstances of rungs.
- Discern among different timer types, such as TOF and TON, and grasp their distinct behaviors.

Final Answer :
A
Explanation :
A TOF (Timer Off-Delay) timer starts to accumulate time when the rung makes a true to false transition. This means the timer begins its timing operation once the input condition switches from being true (or on) to false (or off).
