5.3 Output Instructions
Processing details
• These instructions start time measurement, triggered by the coil specified by (d) (in SD language or FBD/LD, displayed as
Coil), when the operation result up to the OUT instruction is on. When time is up (current value
set value), the normally
open contact turns on (continuity state) and the normally closed contact turns off (non-continuity state).
• When the operation result up to the OUT instruction turns off, the contact responds as shown below.
• To clear the current value of the long retentive timer and turn off the contact after time is up, use the RST instruction.
• When the timer set value is 0, the time will be up at execution of the OUT instruction.
• The following operations are performed at execution of the OUT instruction.
• If the OUT LT instruction is skipped by using such as the JMP instruction while the OUT LT or OUT LST instruction is on,
the current value is not updated or the contact is not turned on or off.
• If the same OUT LT or OUT LST instruction is executed two times or more in a single scan, the current value is updated by
the number of times the instruction is executed.
• The timer limit value is set in parameter using the engineering tool.
Long timer/long retentive timer: 0.001 to 1000ms (in increments of 0.001ms) (Default: 0.001ms)
• For the counting method, refer to the following.
MELSEC iQ-R CPU Module User's Manual (Application)
Precautions
To create a program in which the operation of a long timer contact triggers the operation of another long timer, program the
long timers in order from the one that operates last.
In the following cases, if a program is created in order of timer measurements, all timers turn on in the same scan.
• The set value is smaller than the scan time.
• The set value is 1.
Ex.
When timers LT0 to LT2 are programmed in order from the one that measures last

• The coil used as a trigger of the OUT LT or OUT LST instruction turns on or off.
• The contact used as a trigger of the OUT LT or OUT LST instruction turns on or off.
• The current value of the OUT LT or OUT LST instruction is changed.
(1) Long timer LT2 starts measurement from the next scan after the contact of
long timer LT1 turns on.
(2) Long timer LT1 starts measurement from the next scan after the contact of
long timer LT0 turns on.
(3) Long timer LT0 starts measurement when X0 turns on.
