| What is the difference between Timer ON Delay, Timer OFF Delay and Timer Pulse? |
|
 |
| As for Timer ON Delay, Timer starts by turning ON the timer trigger bit, and the timer output bit turns ON when the setup time has passed. As for Timer OFF Delay, the timer output bit turns OFF when the setup time has passed after the timer input bit had turned OFF. As for Timer Pulse, it starts when the timer input bit is turned ON by 1st pulse and keeps outputting during the setup time. |

| ・Timer ON Delay |
 |
When the timer input bit (IN) receives power, the TON instruction adds the preset time (PT), in milliseconds, and the timer output bit (Q) turns ON. |
| |
|
| ・Timer OFF Delay |
 |
When the timer input bit (IN) stops receiving power, the TOF instruction adds the preset time (PT), in milliseconds, and the timer output bit (Q) turns OFF. |
| |
|
| ・Timer Pulse |
 |
When the timer input bit (IN) receives power one time, the TP instruction turns ON the output bit (Q) for the duration of the preset time (PT), in milliseconds. |
