Programmable Logic Controllers : Hardware and Programming

__**Programmable Logic Controllers: Hardware and Programming**__ provides an introduction to PLCs and their applications in process and industrial control systems. The text begins with basic hardware and programming concepts and then progresses to system-level applications. * To prepare technicians to meet the needs of industry, the author has taken a highly practical approach, covering PLC applications, maintenance, testing, and troubleshooting. * Illustrations and examples help to explain abstract concepts, and review questions at the end of each chapter allow students to practice what they have learned. * The thoroughly updated new edition includes a new chapter on RSLogix5000 programming and expanded coverage of HMI (human machine interface) applications.
