TOF Timer on VisiLogic

[Paolo]

Hi All,

just only to confirm what I think......

In VisiLogic I need to use an delay off timer, but looking in the library instructions I didn't find a delay off timer....

I see only Delay On Timer (TD), Accumulated Timer (TA) and Extend pulse  Timer (TE).

Maybe I have to develop an TOff timer?? Or maybe I'm wrong??

Thanks in advance

Yes, those are the 3 timer types available - and those are all you need. You can create any other type of timer easily from those three. For a TOF, just use an inverted contact as the activating condition.

not enought.........

Correct use an inverted contact as activating condition for the TD, but I need to insert an additional rung or net just to latch my coil with the same contact used to manage the TD and then reset the coil when the TD reached the time set.

Anyway thanks for your support.

Cheers
