The purpose of the functional analysis is to define a clear picture of the scope, architecture, and functionality of substation automation systems, as addressed by this security profile. The real-world specific performance of substation automation system functions varies in terms of function, scope, and technology from device to device and component to component among different system offerings and deployments. However, this profile approaches the problem by defining a set of abstract roles that capture essential functionality that may be realized through a variety of implementations. For example, the functions of the Substation User Interface role may be performed by a stand-alone component, or rolled into a platform that also performs many of the remote access functions as defined in the Proxy role. Conversely, some implementations may have the decision-making functionality of the Control Authority role distributed among several devices that also implement the Substation User Interface, the Proxy, and possibly even a Control Application. Regardless, this profile defines roles in such a way that the logical architecture and state machine functionality may be used to represent a wide variety of real-world implementations
