Timer and Counter Instructions
Section 3-6
Description
When the timer input is OFF, the timer specified by N is reset, i.e., the timer’s
PV is reset to the SV and its Completion Flag is turned OFF.
When the timer input goes from OFF to ON, TIMH(015)/TIMHX(551) starts
decrementing the PV. The PV will continue timing down as long as the timer
input remains ON and the timer’s Completion Flag will be turned ON when the
PV reaches 0000.
The status of the timer’s PV and Completion Flag will be maintained after the
timer times out. To restart the timer, the timer input must be turned OFF and
then ON again or the timer’s PV must be changed to a non-zero value (by
MOV(021), for example).
The following timing chart shows the behavior of the timer’s PV and Comple-
tion Flag when the timer input is turned OFF before the timer times out.
