At the end of the time duration, the output, will return to false. Further false-to-true transitions of the combined input while PRE_OUT_D is true will be ignored. true PV_D false true PRE_OUT_D false * See note 1 * See note 1 TIM ER_SP OUT_EXP 0 TIM ER_SP OUT_REM 0 TIM ER_SP * Note 1: Returns to zero if QUIES_OPT = CLEAR TIM ER_SP Time Timer Example when TIMER_TYPE = PULSE • If TIMER_TYPE is RT_PULSE, (Re-Triggerable pulse type) a false-to-true change on the combined input, PV_D, will initiate a true pulse at PRE_OUT_D whose duration is determined by the TIMER_SP value. At the end of that time duration PRE_OUT_D will return to false. If the combined input returns to false and presents a subsequent false-to-true transition while the timer is timing, the timer shall be reinitialized and PRE_OUT_D shall continue to be true. 2.153
