Virtual Automation System are classified as a System or Collection of Systems that mimick the function of device, that does function traditionally as a single unit. All modern SCADA Systems can be classified as "Virtualized". Virtualization enables primitive devices to gain additionally functions and behave like a integrated unit, without being one.

Virtualized automation systems work by enumerating Physical interfaces to primitive devices, processing the resources and Creating complex schemas and integration functionality.

Virtualized Systems then have no full autonomy on the devices but do constantly monitor and request the device, to perform actions whenever possible.

@@ Line 21: / Line 21: @@
 Slow field bus systems, bad planning and poor device configuration (i.e. talkative devices) can sometimes lead to problems like bottlenecking, that slows down the links to the devices when flooded with informations. To counter those issues, systems must be planned and tested considering maximum throughput on the links. Some high throuput bus systems or those who establish secondary physical links are usually not affected by bottlenecking.
 '''Single point of Failure '''
 A SCADA System that claims full autonomy can represent a single point of failure, as the system will not operate when the automation system or software is unavailable "''Crashed''". Most automation Systems include watchdogs, automatic restarting or even fallback systems, that cover for a failed system. Fallback systems are required for Places where a faulire can present damage to Objects.
 '''Limitations '''
 History has proven that safety functions like hardware interlocks must never implemented by protentially unreliable computer systems. as only specialized and certified computer systems may implement these features, most automation system require to attach special hardware devices for safe and conformant functionality in applications where malfunction present danger to life or goods.
