ABSTRACT
This chapter explores the application of networked control systems (NCS) in the domains of control, diagnostics, and safety in manufacturing. It explains the parameterization of networks with respect to balancing Quality of Service capabilities and introduces common network protocol approaches and differentiates them with respect to functional characteristics. The chapter presents a method for NCS evaluation that includes theoretical, experimental, and analytical components. It also explores network applications within the domain of manufacturing; these include application sub-domains of control, diagnostics and safety, as well as different levels of control in the factory such as machine level, cell level, and system level. The chapter discusses a multilevel factory networking solution that supports networked control, diagnostics, and safety. It deals with a discussion of future trends in industrial networks with a focus on the move to wireless networking technology. Issues with the migration to wireless include interference between multiple wireless networks, security, and reliability and determinism of data transmission.
