Programmable Logic Controllers: Principles and ApplicationsThis practical and clearly written introduction provides both fundamental and cutting-edge coverage on programmable logic controllers; today a billion dollar industry. It combines comprehensive, accessible coverage with a wealth of industry examples that make intangible concepts come to life-- offering users a broad-based foundation that will serve them well on the job. The volume examines every aspect of controller usage in an easy-to-understand, jargon-free narrative. Beginning with a basic layout the book goes right into programming techniques, it progresses through fundamental, intermediate, and advanced functions-- and concludes with chapters on related topics. Applications are discussed for each PLC function, and vast arrays of examples and problems help users achieve an understanding of PLCs, and the experience needed to use them. For programmers and others working with PLCs. |
