When the Timer Off-Delay instruction is de-energized, what happens to the accumulated value?

When the Timer Off-Delay instruction is de-energized, it maintains the last accumulated value. This behavior is essential for applications where you need to keep track of the timing even when the controlling input is turned off. The timer does not reset to zero immediately, allowing the user to retrieve the last measured time interval before the timer is re-energized. Essentially, the timer captures an output state based on when it was last active, enabling seamless control in scenarios like motor delays, light transitions, or other similar applications where timing continuity is crucial.

In practical terms, once the timer is de-energized, instead of resetting or stopping the count, it allows the accumulated time to remain available for reference. This characteristic can be vital for various control strategies where time-tracking is necessary regardless of the active state of the input signal.
