Function Explanation

The TON instruction is defined as the function of a timer for the ON delay.

When In is TRUE, the timer starts to measure the time and the value of ET increases accordingly.
When ET equals PT, Q is TRUE. When In is set to FALSE, the measuring of the time stops and Q
and ET are both reset.

Precautions for Correct Use
When the output value of ET reaches the set value of PT , the timer stops measuring time. ET is reset to 0
(0ns) when In changes from TRUE to FALSE.
