 Using the Timer Function
The multi-function digital input terminals S3 to S7 can be used as timer function input terminals, and multi-
function output terminals M1-M2, M3-M4, and M5-M6 can be used as timer function output terminals. By
setting the delay time, you can prevent chattering of the sensors and switches.
• Set one of the parameters H1-01 to H1-05 (digital input terminal S3 to S7) to 18 (timer function input).
• Set H2-01 to H2-03 (multi-function output terminals M1-M2, M3-M4, and M5-M6 function selection) to
12 (timer function output).

Multifunction Outputs (H2-01 to H2-03)
Setting Example
When the timer function input ON time is longer than the value set in b4-01, the timer output function is
turned ON. When the timer function input OFF time is longer than the value set in b4-02, the timer output
function is turned OFF. An example of timer function operation is given in the following diagram.
