9 Function modules
The time resolution of the delay time depends on the cycle time of the device (example: 150 ms).
Example
TON01(IN, 6, 2);
(* IN = TRUE sets after 6 seconds TON01.Q to TRUE.
TON01.Q remains TRUE as long as IN = TRUE.
TON01.ET returns the elapsed time in seconds from IN = TRUE to TON01.Q = TRUE (max. 6
seconds) or to IN = FALSE. *)
