This book is an excellent text for students in automatic control systems and is a useful reference for those working in the industry. It focuses on the functions of process control for industrial applications: sensing (measuring) process variables, communicating the sensed data to a central analyzer, deciding on a tactic to adjust the process, and actual adjustment of the process. Design, operation, and maintenance procedures are described. Design procedures include the selection of hardware and software, as well as applications to improve production and reduce costs. Operational procedures include monitoring the presented and recorded data to confirm satisfactory process operation, monitoring the achievement of cost goals, and ensuring that backup equipment functions correctly. Maintenance procedures include calibration of equipment, monitoring the effects of the environment on the system, and repairing more
