5.3.5 Timer processing
The CPU timer is an incremental timer, which increases its present value according to the measuring time. Three types
of On Delay Timer (TON), Off Delay Timer (TOF) and Pulse Timer (TP) are available. Its measuring range is 0.001 to
4,294,967,295 sec (1,193 hours) by 1 ms. For details, refer to “GLOFA-GM programming”.
1) On Delay Timer
: Process Time Change and Contact On/Off
Timer Process time is newly changed when the timer function block is executed. When the process time reaches the
setting time (process time = setting time), the Timer output contact turns on.
On Delay Timer Timing Diagram is shown as below.
2) Off Delay Timer
: Process Time Change and Contact On/Off
y
If input condition turns on, timer output contact (Q) turns on. If input condition turns off, timer process time starts
increasing.
y
The process time is newly changed when the timer function block is executed. When the process time reaches the
setting time (process time = setting time), the contact (Q) turns off. The following diagram shows Off Delay Timer
