Title: Delta contact
Post by: PLCwannabe on April 01, 2025, 11:23:51 AM

The attached rung is not working as i think it should.The c900 is bit will run the program everytime, but the $now.hour delta contact will not make the program run. What am I missing here?

Not sure. It's working for me as expected. You might try driving an INC instruction just to see what it's doing. I usually find that to be the easiest way to test.

Got this figured out, it was bad programming on my end.

I hate when it does what I told it to instead of what I wanted it to!
