You have to select T250 Timer for this tutorial. The retentive timer range start form this Timer.

I just create the M1 bit for understanding the retentive timer function.

Now, Here we create Y0 Output which is On depending on status for T250.

See the timer value it didn't get zero even if the input contact OFF.

Here we use M2 to reset the timer value.

And finally when time over then T250 contact become On and Y0 coil also On.

But the problem was, how can we Off the Y0 Coil.

So that to Off the Y0 Coil , we take M2 contact and reset the T250 Timer.

Finally you can able to hold the timer value as well as you can control the output.
