1. Off-Delay timer
The Off-Delay Timer is used to delay turning an output OFF for a
fixed period of time after the input turns OFF.
When (IN) turns ON, the timer bit turns ON immediately, and the
current value is set to 0.
When (IN) turns OFF, the timer counts till PT and the timer bit
turns OFF and the current value stops counting.
If the input is OFF for a time shorter than PT, the timer bit
remains ON.

10. Memory addressing
You can access data in many CPU memory areas (V, I, Q, M, S, L,
and SM) as:
bytes, words, or double words by using the byte-address format.
