Automation Direct Gurus

I have a small project that I is undocumented. No big deal I have the HMI (EZtouch & C-More) projects and I have copied the tag info that I could. There are addresses that are used in the PLC and not used in the HMI That look like they are Alarm status tags and not not being used in the HMI.

How can I see if they are being used in some backdoor fashion that is just not jumping out at me. I have been through the tag database several times and don't see anything. I looked under the event manager in the C-More, the Alarm database in the EZTouch panel editor.

I think they are addresses that never got added to the project and are in limbo.

Can you force them on and see what happens? if nothing happens the odds are someone just wrote the program like I do

Yea I missed my window to do that by about 5 hours. So after a week or two I may get my chance again. If I am still at this company.
