When the input is disconnected, timing starts until the current time is equal to the preset time, then timing stops.

2) When the preset value is reached, the timer bit is disconnected and the current value stops incrementing; If the input is turned on again before the TOF reaches the preset value, the timer bit remains on.

3) For the TOF timer to start timing, the enable input must perform an on-off transition.

Precautions

• Avoid timer number conflict: the same timer number cannot be used for TON, TONR, TOF, TP, OUT_T timers at the same time. For example, TON T32 and TOF T32 cannot be used at the same time (it may cause data confusion and not achieve the effect of the corresponding instruction function).

3) After starting, if the enable input becomes FALSE before the timer (s1) reaches the expected time (s2), the timer will be reset after reaching the expected time (s2).

Precautions
