This document defines a CPS as follows:
Cyber-physical systems integrate computation, communication, sensing, and actuation with physical systems to fulfill time-sensitive functions with varying degrees of interaction with the environment, including human interaction.
CPS should be characterized by well-defined components. They should provide components with well-known characteristics described using standardized semantics and syntax. Components should use standardized component/service definitions, descriptions, and component catalogs.
Components that contain sensors and/or actuators should have an appropriate level of awareness of physical location and time. For example, the accuracy requirement for location will change based upon the application. To support such applications, components may need the ability to access and/or report both location and the associated uncertainty of the location.
component: Modular, deployable, and replaceable part of a system that encapsulates implementation and exposes a set of interfaces.
