5.2.6 1-s OFF-Delay Timer (TOFF[1s])
( 1 ) Operation
The timer counts the time whenever the timer bit input is 0 (OFF). The bit output is set to 1 (ON) when the count value
equals the set value.
If the bit input changes to 0 (OFF) during counting, the timer will stop counting. If the bit input changes to 1 (ON)
again, the timer starts counting again from the beginning (i.e., from 0). The actual counted time (in units of 1 s) is
stored in the Count register.
ΠThe counting error is 1 s or less.
( 2 ) Format
∗ C and # registers cannot be used.
