1) Off-delay timer
The timer turns the output OFF after a set period of time.

indicated in line A.
• When X020 is set OFF, Y005 is latched
and timer T1 turns ON as indicated in line
B.
• After the set value of timer T1 elapses
(K30 = 3 sec), C turns OFF, and the OUT
instruction Y005 and T1 are turned OFF.
2) One-shot timer
The timer keeps the output ON for a set period of time.
(Even if the input for operating the timer remains ON, the output is turned OFF after a set
period of time.)
• When X021 is set ON, Y006 and T2 turn
ON as indicated in line A. X021 is turned
