This volume is designed to help readers develop a good general working knowledge of programmable controllers with concentration on relay ladder logic techniques and how a PLC is connected to external components in an operating control system. The text uses real world programming problems that students can solve on any available programmable controller or PLC simulator. Later chapters relate to more advanced subjects in machine controls, which makes this a welcome addition to a personal technical reference library.
