I got the 5/05 to take the firmware upgrade, it took about 10 tries before it was successful though.
The HMI does see it now and is working properly. I have been bench testing all the objects and displays on all the screens.
I am thinking that when everything is tested I will program this 5/05 as an upgraded replacement for the line in use and swap it out quickly. Then have time to update the other one for the add-on panel.
Thanks for the help.
