Cool. The Event viewer made a nice alarm history. I put in some test logic in the PLC to trigger all the alarms so I could verify them, and it all works great.
The trend chart for a tank level is awesome too, and I was a little worried when I saw how few things can be configured in C3, but it works great and has more than enough navigation options for this application.
I still have a solid red alarm LED, but I am not going to worry about that (it's tiny anyway...).
Black permanent marker!!! $0.75 USD at Office max OR electrical tape (not integrated to C3 solution, use at your own risk)!!!
The contrast between this thing and the PV300 Micro it replaced is stunning. It's like switching from Pong to Playstation3.
Thanks for all your help guys, I am going to put a bow on this one and call it a Friday...
