Gordon Clarke

In sixteen diverse and entertaining stories, Gordon R Clarke takes us on a journey from the struggle of ancient rebels to the aromas of an unexpected future, delivering the flavours of five continents, spiced with both comedy and philosophy. He leads us through the terrors of madness to the peace of the Thai countryside by way of an indiscreet Christmas letter from Spain, a funeral in North Carolina, a pizza incident in Singapore, an altercation in Crete, and a mysterious evening in Budapest. Throughout, the question of what is real and what we can never know haunts the collection, reminding us not only of the impermanence of all things but also the joy of human connection.

SCADA (Supervisory Control and Data Acquisition) systems are at the heart of the modern industrial enterprise ranging from mining plants, water and electrical utility installations to oil and gas plants. In a market that is crowded with high-level monographs and reference guides, more practical information for professional engineers is required. This book covers the essentials of SCADA communication systems focussing on DNP3, the IEC 60870.5 standard and other new developments in this area. It commences with a brief review of the fundamentals of SCADA systems' hardware, software and the communications systems (such as RS-232, RS-485, Ethernet and TCP/IP) that connect the SCADA Modules together. A solid review is then done on the DNP3 and IEC 60870.5 protocols where its features, message structure, practical benefits and applications are discussed. This book provides you with the knowledge to design your next SCADA system more effectively with a focus on using the latest communications technologies available.
