Freelance upgrade to 800xa
I was wondering if there is any ABB documents regarding upgrade of HMI part of a Freelance network to 800xA ?
As they say "there is a Connect for that". Search for "800xA for Freelance".
Also see web page I attached as a source.
If You need a more specific info, feel free to follow up this answer and I will try to give more info/sources.
Hope this helps,
