The Modern industrial environment is steered with the latest technological advancements in computer and Communication. Programmable Logic Controllers (PLC) based automaton is the outcome of that. This book has been prepared as a textbook to give an insight into these areas.
Divided into seven chapters, Chapter One presents the basics of PLCs and Chapter Two establishes a bridge between digital logics and ladder logics. PLC timers and counters have been dealt with in Chapter Three while commonly used advanced instructions are presented in Chapter Four. In Chapter Five, PLC I/O and power supplies, which are the lifelines of PLCs, have been covered. Modern concepts of communication as applied to plant automaton have been included in the revised version. In chapter seven, modern automaton concepts have been highlighted. Concepts of DCS and SCADA using PLCs are elaborated. Finally, usage of PAC has also been depicted. This will give an idea to the readers a concept of modern plant automaton schemes. Additionally, each chapter is provided with some practical examples, exercises and multiple choice questions.
