(2) The contact responds as follows when the operation result up to the OUT instruction is a change from ON to OFF:
Type of Timer
Timer Coil
Low speed timer
High speed timer
Low speed
retentive timer
High speed
retentive timer
(3) To clear the present value of a retentive timer and turn the contact OFF after time up, use the RST instruction.
(4) A negative number (-32768 to -1) cannot be set as the setting value for the timer.
If the setting value is 0, the timer will time out when the time the OUT instruction is executed.
*3:
When specifying a setting value for the timer using a word device (D, W, R, ZR, J
the setting range is not checked. Check the value in the user program so that a negative number is not set.
(5) The following processing is conducted when the OUT instruction is executed:
• OUT T
coil turned ON or OFF
• OUT T
contact turned ON or OFF
• OUT T
present value updated
In cases where a JMP instruction or the like is used to jump to an OUT T
ON, no present value update or contact ON/OFF operation is conducted.
Also, if the same OUT T
number of repetitions executed will be updated.
(6) Indexing for timer coils or contacts can be conducted only by Z0 or Z1.
Timer setting value has no limitation for indexing.
Remark
1. Timer's time limit
Time limit of the timer is set in the PLC system of the PLC parameter dialog box.
