Remarks
This instruction can be used as an ON-delay timer in the same manner as
arelay circuit. The set time can be between 0 and 999.9 seconds. Timer
numbers can be set from 00 to 47. Do not give timers and counters the
same number.
The timer starts when the content of the result register is logical 1 and
resets when the content of the register is logical 0.
A time-up contact designates the timer number itself. Both NO and NC
contacts can be used in the number required.
The timer works by decrementing, producing an output when the present
value (the time remaining) becomes 0000. When input to the timer is
turnéd off, the timer is reset and the present value returns to the preset
time.
The
timer
output
is
transmitted
externally
through
an
output
relay
as
shown in the circuit example.

The set value for the TIM/CNT instruction cannot be set on a channel
basis.
Memory retentive timer
If a power failure occurs, the timer is reset and the present value returns
to the preset value. Therefore, if it is necessary that the current value of
the timer be retained in the event of a power failure, a memory retentive
timer circuit must be used for the program. The example circuit is
configured by combining the PC's clock and the counter instruction with
Special Auxiliary Relay 1901 used to generate a 0.2sec puise.
