Highway Addressable Remote Transducer (HART) was developed in the mid to late 1980s by Rosemount, as a digital replacement for 4-20 mA technology for transmitting a process variable for analog instruments. Today, it is the world's most often used protocol for process automation. In this book, the author, James Powell, uses his 18 years of HART technical support and product development knowledge to produce a practical guide on how to use HART. This book is written for people who work with HART, and it will truly assist in making projects successful. The purpose of this guide is to look at the protocol from a practical point of view and show how to use it properly. What Automation Professionals Think About This Book: "A logical, useful guide! This book serves to provide the reader with a realistic and factual resource that can fully prepare Engineers for any HART / HART-IP / HART Wireless inquiry that may arise. It provides useful descriptions and tips on good design, integration and troubleshooting. It is refreshing that this document serves not as another infoglut, but rather a useful guide to assist you in real-life applications. "Kyle RoosTechnical Trainer, Sales & Marketing team lead, IDX Industrial Data Xchange, South Africa. "Following on from his equally informative book on Profibus, Catching the Profibus Fieldbus, James has succeeded in writing a concise introduction to the Hart protocol that I would thoroughly recommend to anyone with an interest in this widely used industrial automation protocol."
