TP
The TP instruction outputs TRUE while the set time elapses after the timer starts.
* T#0ms to T#106751d_23h_47m_16s_854.775807ms
The TP instruction outputs TRUE while the set time elapses after the timer starts. Set the time in nano-
seconds (ns). The timing accuracy is 100 ns. The timer starts when timer input In changes to TRUE and
timer output Q changes to TRUE. Elapsed time ET is incremented as time elapses. When ET reaches
set time PT, timer output Q changes to FALSE. ET is not incremented after that. The timer is reset when
In changes to FALSE. ET changes to 0. The timer is not reset even if In changes to FALSE after the
timer starts but before ET reaches PT.
