1.6 1-S OFF-DELAY TIMER Instruction (TOFF[1s])
[Outline]
The TOFF[1s] times while the immediately-preceding value of the bit input is OFF. The value of the
bit output is set to OFF when the timer value reaches the set value. The timer stops when the
immediately-preceding value of the bit input is set to ON during timing. When the bit input is set to
OFF again, timing restarts from the beginning (0). A value equal to the actual timed time (1s Unit) is
stored in the timer value register.
