TABLE OF CONTENTS LabVIEW Graphical Programming, Fourth Edition
Process Control Basics
In this chapter, we'll cover the important concepts of process control and then design the pieces of a small process control system, using good LabVIEW practices. First, a plug for the ISA: The U.S.-based Instrumentation, Systems, and Automation Society (ISA) sets many of the standards and practices for industrial process control. Gary joined the ISA some years ago while working on the control system for a large experimental facility, and he found his membership to be quite helpful. It offers a catalog of books, publications, standards documents, and practical training courses that can make your plant and your work practices safer and more efficient. The concepts and terminology presented in this chapter are straight out of the ISA publications, in an effort to keep us all speaking a common language. For information about membership or publications, contact the ISA at www.isa.org.
Industrial Standards
Standards set by the ISA and other organizations address both the physical plant including instruments, tanks, valves, piping, wiring, and so forth as well as the man-machine interface (MMI) and any associated software and documentation. The classic MMI was a silk-screened control panel filled with controllers and sequencers, digital and analog display devices, chart recorders, and plenty of knobs and switches. Nowadays, we can use software-based virtual instruments to mimic these classic MMI functions. And what better way is there to create virtual instruments than LabVIEW?
Engineers communicate primarily through drawings, a simple but often overlooked fact. In process control, drawing standards have been...
