Have you tried shutting down RSLinx when you are using AHMI?

The buttons show "Invalid SLC/Micro Address" which means that your addresses are not in correct format.

Your address shows as I0:0 and the format should be I:0/0 but as Archie mentioned, you can not control physical inputs through AHMI (you have to bypass them with B3:0/x bits in your rungs).

I0:0 is not a valid address. I am assuming you mean to use I:0/0

However you cannot use physical inputs for HMI buttons unless you intend to never put the PLC in run mode. If it is not put in run mode, then your ladder logic is irrelevant because it will never execute therefore never turn on outputs.

I recommend you watch the PLC Training videos on YouTube by Ron Beaufort. He does a very good job at explaining the PLC cycle and Input/ Output data tables.

The proper way is to use internal bits such as B3/0 and B3/1 for your buttons
