Diference between Freelance System and 800XA System
someone has one summary doc that explain main diferences between ABB System Freelance and ABB 800XA.

unfortunately there is no document (to my knowledge) that describes the difference.
It is like in the car industry. All cars can drive, but the one you choose depends on your preferences, needs and budget.
For big power plants you would consider Symphony plus. Outside of this area ABB offers the essential automation (Freelance & Compact Products) and the extended automation (800xA).
If you are interested in a straightforward, easy to learn process automation system you go for Freelance.
If in addition to the basic automation needs you are interested in integrated process optimizing, asset management sophisticated alarm management etc you would consider 800xA
It is not that you couldn't do those tasks with Freelance, but opposed to 800xA where those bells and whistles are integrated you would add them as coupled solutions to Freelance.
This is in short a black and white picture of a world that actually has many shades of gray.
Freelance is a controller range that was developed from the Hartman and Braun Freelance controllers. It uses "Digivis" as an operator interface and is programmed using Control Builder F
800xA is a full function HMI that can be used with ANY controller from ABB's controller range including the Freelance Controllers and Control Builder F. It is designed as a drop in replacement for the HMI's on pretty much all ABB controllers including AC400, MOD, DCI, Harmony etc. using "integration" packages. You can also integrate pretty much any OPC based control system to 800xA using PLC connect.
For new sites and new 800xA systems, the prefered controller for 800xA is the AC800M. The AC800M controller integration comes as standard with 800xA. So typically most "800xA" users see the AC800M controller as part of the 800xA system rather than a separate controller range. And this is also how ABB markets the product.
The AC800M controllers are also offered as a stand alone controller system for smaller projects under the name of "Compact Products". Compact HMI is a cut down version of 800xA
