Hi

Is it possible to Reset the time value of an TOF timer? (if an fault occurs, then the timer can be stopped)
I have seen a function in TIA to reset a TOF timer. (Belive it's called RT)

Hi Emil,

good to see you again :D .

Well, as you already have seen do we currently not have a way to reset the TOF, but I'll check internal if this might be a feature for further versions.
I'll keep this post updated.

Have a great weekend,

Hi Emil,

I've just spoke with the PM of PLCnext Engineer.
This is an interesting request, but as the TOF were specified in the 61131 we would keep the FB as it is.
But if there were more requests for such a feature, it would be a possibility to create a specilized FB...

Have a great weekend,

Dont know if this is what you are looking for but I made my own Timer that looks like the attached.

The first is a simple auto reset timer and the second is a little bit more labor but it is an accumulating timer with a reset input.

I may have over thought this and made it more complicated than it needed to be but Ive been using it in my programs flawlessly so far.
