The CitectSCADA runtime system is a Windows-based application that runs in the standard Windows environment. Typically, Windows allows you to run several applications at the same time, however, this may impact performance or obscure runtime messages and information if you require a computer to be dedicated to Runtime.
For example, an operator display panel may be used to present alarm notifications. You don't want the Runtime screen minimized or hidden behind another window.
There are several different ways can limit access to software other than CitectSCADA.
