Timer and Counter Instructions
Section 3-6
Description
When the timer input is ON, TTIM(087)/TTIMX(555) increments the PV. When
the timer input goes OFF, the timer will stop incrementing the PV, but the PV
will retain its value. The PV will resume timing when the timer input goes ON
again. The timer’s Completion Flag will be turned ON when the PV reaches
the SV.
The status of the timer’s PV and Completion Flag will be maintained after the
timer times out. There are three ways to restart the timer: the timer’s PV can
be changed to a non-zero value (by MOV(021), for example), the reset input
can be turned ON, or CNR(545)/CNRX(547) can be executed.
Flags
Precautions
Timer numbers are shared with other timer instructions. If two timers share
the same timer number, but are not used simultaneously, a duplication error
will be generated when the program is checked, but the timers will operate
normally. Timers which share the same timer number will not operate properly
if they are used simultaneously.
