Study the Limited On-Time Timer application in Programmable Logic Controller with an example.
This example illustrates a situation in which two outputs go on at the same time.
Then, one of them is to go off after a preset period of time.
One output, O:2/0, stays on; the other output, O:2/1, turns off at the end of the timing interval.
Resetting is accomplished by turning I:1/0 off.
