What does the Timer Off-Delay instruction do when it is de-energized?

The Timer Off-Delay instruction functions during the de-energization of an associated control input. When the control input is turned off, the timer begins counting down from its previously set duration, which represents the 'off-delay' period. During this countdown, the accumulated value increases as time elapses—this accumulated value reflects the amount of time that has passed since the timer was de-energized. Therefore, as long as the timer is in the off-delay state, the accumulated value continues to increase until the timer reaches zero, at which point the timer would stop counting and maintain its accumulated time.

This behavior is crucial for applications requiring a specific delay period after an input has been turned off, allowing the system to execute actions even after the initial signal has ceased.
