• After the timer times up, clear the current value of the retentive timer and turn the contact off by the RST instruction.
• When the set value is 0, the timer times up when the OUT instruction is executed.
• The following processing is executed when the OUT instruction is executed:
• The coil in the OUT T, OUTH T, OUTHS T, OUT ST, OUTH ST and OUTHS ST instructions turns ON/OFF
• The contact in the OUT T, OUTH T, OUTHS T, OUT ST, OUTH ST and OUTHS ST instructions turns ON/OFF
• The current value in the OUT T, OUTH T, OUTHS T, OUT ST, OUTH ST and OUTHS ST instructions changes
• When the OUT T instruction is skipped using the CJ instruction, etc. while the OUT T and OUT ST instructions are ON,
these instructions do not update the current value or turn ON/OFF the contacts.
• When the same OUT T and OUT ST instructions are executed in the same scan twice or more, these instructions update
the current value for the same number of times of execution.
Values used for timers can be set in the range 1 to 32767. Actual timer constants are as follows since the
OUT, OUTH, and OUTHS instructions operate as 100 ms, 10 ms, and 1 ms timers, respectively.
• OUT instruction: 0.1 to 3276.7 seconds
• OUTH instruction: 0.01 to 327.67 seconds
• OUTHS instruction: 0.001 to 32.767 seconds
For the counting method, refer to the following.

Precautions
When creating a program for measuring another timer at a timer contact, program in order starting with the timer to be
measured later on. In the following instance, all timers turn on in the same scan when the program is created in the
measurement order.
• When the set value is shorter than the scan time
• When the set value is 1
Ex.
When the T0 to T2 timers are programmed in order from the timer that is measured later

(1) The T2 timer starts measurement from the scan following the scan where the T1
contact turns ON.
(2) The T1 timer starts measurement from the scan following the scan where the T0
contact turns ON.
(3) The T0 timer starts measurement when X0 turns ON.
(1) The T0 timer starts measurement when X0 turns ON.
(2) The contacts of the T1 and T2 timers also turn on when the contact of T0 turns ON.
