The AccumulationTimer instruction totals the time that the timer input is TRUE. Set the time in nanosec-
onds (ns). The timing accuracy is 100 ns. If reset Reset is FALSE, the timer starts when In changes to
TRUE. Total time ET is incremented as time elapses. The timer stops when In changes to FALSE. ET is
held. When In changes to TRUE again, the timer starts again. ET is incremented from the value that
was previously held. When ET reaches set time PT, timer output Q changes to TRUE. ET is not incre-
mented after that. The timer is reset when Reset changes to TRUE.
ET changes to 0 and Q changes to FALSE.
