AC800F regarded as scada system ?
what are the limitation?

AC 800F is a controller - a piece of hardware, typically used for processing tasks and programs. It's a part of Freelance, a DCS (Distributed Control System), which is an integrated solution for automation (both hardware and software included).
On the other hand SCADA (Supervisory Control And Data Acquisition) is software, that works on top of the controllers. It characterized by open architecture (can work with many types of controller from different vendors) and takes a role of HMI (Human-Machine Interface).
It's not a full characteristic of either DCS or SCADA, but I'm sure it makes quite clear that AC 800F can't be regarded as SCADA in any way.
The part of Freelance system, that can be used as SCADA, is the Operation software - DigiVis. Still, you get the most of Freelance if You use it as DCS - You get full DCS capabielieties, can connect with AC 700F, AC 800F or AC 900F controllers seamlessly and can still integrate third part controllers.
Freelance is a distributed control system consisting of Freelance controllers like AC800F and Feelance operation with DigiVis.
The term SCADA is also used sometimes for an PC-based HMI without special SCADA features like telecontrol.
DigiVis can be used as a PC-based HMI as also as ABB's Compact HMI. AC 800F controller etc. are used below SCADAs and are connected i.e. via telecontrol.
Freelance operation and control level together can fulfill requierements of a SCADA.
But if only SCADA functionalities without Freelance controllers are requiered, I would prefer an SCADA of ABB like SCADAvantage.
