Continuous and Discrete Control for the Process Industry
About the Book

In this book the authors address the wireless communication concepts and terminology that are needed to apply wireless control in the process industry. The control system interfaces and wireless field devices described in this book are based on wireless standards for industrial settings and can be used in monitoring and control applications.


Wireless transmitters were initially only used to monitor the process, not to control it. However, over the last seven years wireless measurement has earned high user confidence, and new control techniques have been devised to deal with the characteristics of wireless. Based on the broad acceptance of wireless transmitters, many manufacturers are in the process of developing and introducing wireless final control elements such as on/off and throttling valves.


The book details the recent technical innovations that address control using wireless measurements and final control elements. It presents how control can be structured to manage the slow and non-periodic measurement update rates provided by a wireless transmitter and to compensate for communication delay to the final control element. These new control techniques make it possible to use wireless measurements and wireless valves in closed loop control. The book also presents how wireless measurements may be utilized in model predictive control (MPC).


Multiple application examples are used to show what is required to utilize wireless control. Workshops are included in the book that explores key concepts associated with wireless control. The reader may view the workshop solution by going to the website that accompanies the book.


The book is written for the process or control engineer who is familiar with traditional control but has little or no experience in designing, installing, checking out or commissioning control using a wireless transmitter or wireless valve. The book provides comprehensive coverage of wireless control for both continuous and discrete applications in the process industry. Information is provided on commercially available analog and discrete wireless transmitters and on-off valves.


Since some readers may work with an existing DCS that does not provide native support for wireless field devices, information is provided on how a wireless network may be integrated into a control system using supported serial and Ethernet interfaces. In addition, information is provided on how the PID modifications needed for wireless control may be created using tools supported by the DCS. One chapter of the book addresses how a dynamic simulation of the process and wireless field devices may be easily created in a DCS to support checkout and operator training on wireless control.

Terrence L. "Terry" Blevins has been actively involved in the application and design of process control systems throughout his career. Terry was instrumental in the establishment of Emerson Process Management's Advanced Control Program. From 1998-2005 Terry was the team lead for the development of DeltaV advanced control products. From 1994-2013 he was the Fieldbus Foundation team lead for the development and maintenance of the Function Block Specification and editor of the SIS Architecture and Model Specifications. Terry is the US expert to the IEC SC65E WG7 function block committee that is responsible for the IEC 61804 function block standards. He is a voting member and chairman of ISA SP104-EDDL (Electronic Device Description Language) committee and is the technical advisor to the United States Technical Advisory Group (USTAG) for the IEC65E subcommittee. He is also a member of the USNC TAG (IEC/SC65 and IEC/TC65). Terry coauthored the ISA bestselling books Advanced Control Unleashed (2002), Control Loop Foundation (2010), and Advanced Control Foundation (2012). He has over 50 patents and has written over 80 papers on process control system design and applications. Terry received a Bachelor of Science in Electrical Engineering from the University of Louisville in 1971 and a Master of Science in Electrical Engineering from Purdue University in 1973. In 2004, he was inducted into Control Magazine's Process Automation Hall of Fame. Terry is an ISA Fellow. Presently, Terry is a principal technologist in the applied research team at Emerson Process Management.

Deji Chen recently joined Tongji University as a professor at the Computer Science Department. His research will be focused on Industrial Internet, which is the continuation of his work at Emerson Process Management, where he was a member of the DeltaV future architecture team. Deji has been involved in process automation for almost two decades. He was among the first people who created OPC. He has worked on different fieldbuses including WirelessHART.

He coauthored the first definitive book WirelessHART: Real-Time Mesh Network for Industrial Automation (2010) and translated the ISA bestselling book Control Loop Foundation - Batch and Continuous Processes into Chinese (2012). In 1999 he received his PhD degree from the University of Texas at Austin; the thesis is Real-Time Data Management in the Distributed Environment. Deji is an IEEE senior member and an ISA senior member.
