S7-1200 / TIA V13 positive edge true but no output

[aqueousdan]

Can anyone see why i am not getting an output on this?

it is detecting a rising edge and saying that it is true but going any further to the output coil.

I must be missing something obvious!

The output will only be true for one scan.

If I put a set coil rather than a normal one though it still won't latch on.

I simulated the posted logic with a set coil without issue, perhaps your output address is being referenced elsewhere?

 

[aqueousdan]

Ok yes you were right, it was already being referenced. I redid my code and set and reset works perfectly. I cant see how to delete posts on this forum but i think i need to!

Good to see you found it.
