OUT(T)
• When the operation result up to the OUT instruction is ON, the timer coil turns ON and counts up the value up to the setting
value. When the coil's timer reaches the setting value (counted value  setting value), the contacts enter the following
states:
NO contact Conduction
NC contact Non-conduction
• When the operation result up to the OUT instruction changes from ON to OFF, the following occurs.
Type of timer
100 ms timer
OFF
10 ms timer
100 ms retentive timer
OFF
• After the timer reaches the setting value, the state of the retentive timer contact does not change until the RST instruction is
executed.
• Negative values (-32768 to -1) cannot be set for the setting value.
• The timer's setting value becomes infinity, if its setting value is set to "0". For this reason, the timer does not time up.
• For details on the counting method of the timer, refer to
OUT (C)
• If the operation result changes from OFF to ON up to the OUT instruction, +1 is added to the present value (count value),
and when counting reaches the setting value (present value = setting value), the contact is as follows.
NO contact Conduction
NC contact Non-conduction
• The timer will not start counting if the operation result remains ON. (Count input does not need to be converted into pulse
form.)
• After a count-up, the count value and state of the contact do not change until the RST instruction is executed.
• Negative values (-32768 to -1) cannot be set for the setting value. Furthermore, if the setting value is 0, the same process
as for a setting value of 1 is performed.
• For details on the counting method of the counter, refer to
Execution condition
The OUT instruction is executed for each scan irrespective of the operation result up to the instruction.
Program example
OUT
• Program that outputs to the output module.
• Program that turns X0 ON, and then 10 seconds later turns Y10 and Y14 ON.
