Abstract -- An introduction to the fundamental issues and limitations of communica-
tion and networking in automation is given. Digital communication fundamentals are
reviewed and networked control systems together with teleoperation are discussed.
Issues in both wired and wireless networks are presented.
1 Introduction
1.1 Why communication is necessary in automated systems
Automated systems use local control systems that utilize sensor information in feed-
back loops, process this information and send it as control commands to actuators
to be implemented. Such closed loop feedback control is necessary, because of the
uncertainties in the knowledge of the process and in the environmental conditions.
Feedback control systems rely heavily on the ability to receive sensor information
and send commands using wired or wireless communications.
In automated systems there is control supervision, and also health and safety
