Critical Considerations in the Application of Supervisory Control Systems

A discussion of end devices, and their application to supervisory control systems is presented. The author describes a hypothetical supervisory control application, and discusses system application techniques. Technical merits and/or liabilities associated with each application technique are discussed in conjunction with the associated economics. The paper not only discusses supervisory control systems, but end devices, man/machine interfaces, communication networks, and lightning protection. The paper concludes with the author's impression of what the end user can anticipate from manufacturers of supervisory control systems, end devices, and communication equipment.
