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.
