Timer
OUT T, OUTH T, OUTHS T, OUT ST, OUTH ST, OUTHS ST
The timer counts up to the set value when the operation result up to the OUT instruction is ON and the coil of the timer/
retentive timer specified by (d) turns ON. When the timer times up, NO contact becomes conductive and NC contact becomes
non conductive.

Processing details
• These instructions count up to the set value when the operation result up to the OUT instruction is ON and the coil of the
timer/retentive timer specified by (d) turns ON. When the timer reaches the end of its count (current value set value), NO
contact becomes conductive and NC contact becomes non-conductive.
• Operation is as follows when the operation result up to the OUT instruction changes from ON to OFF.

• 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.
