Known for its comprehensive introduction to PLCs, this completely updated sixth edition of TECHNICIAN'S GUIDE TO PROGRAMMABLE CONTROLLERS covers theory, hardware, instructions, programming, installation, startup, and troubleshooting in a way that is easy to understand and apply. New material has been added to include topics such as sequential function chart programming, function block programming, structured text programming, alarm and event programming, and programming information and examples on the Allen-Bradley ControlLogix family of PLCs. Additional topics include communication networks, basic control signals, linear scaling of analog process signals, and the Proportional Integral Derivative (PID) instructions used by many PLC applications. Supplementary programming examples utilizing the PLC instructions in the text give students a better understanding of the various instructions and how they can be combined to create simple yet effective control logic solutions for today's world.
- This text has been updated to provide detailed programming information and examples on Allen-Bradley ControlLogix family of PLCs.
- Chapters on relevant topics such as "Sequential Function Chart Programming," "Function Block Programming," and "Structured Text Programming" are now included.
- A new chapter, "Alarm & Event Programming," gives readers an understanding of the instructions and PLC programming code that can be used to provide guidance on executing this all important task.
- This text is designed to help readers understand the various communication schemes that are used to pass or exchange information between the PLC and the various control components and control systems.
- The chapter entitled "PLC Programming Examples" encourages application of concepts by giving readers specific examples of PLC programming code and logic utilizing many of the instructions covered in previous chapters.
- Numerous and varied troubleshooting techniques round out the all-inclusive introduction to PLC installation, programming, and maintenance.
