Hello,

I'm hoping someone may be able to help me. I have a small amount of knowledge with ladder logic and FBD. 

I have programmed a basic input counter and output program. It works fine on simulator but when I uploaded it to the Logo 8 and ran the system live to see the inputs highlight etc the counter never counts. 

I have now added a latching relay after the counter and this shows that the counter is giving an output as it goes high and latches. But I can't understand why the counter doesn't show it's counted any inputs.

Any help would be appreciated

Regards

Darryl
