Hailed as the most comprehensive introduction to programmable logic controllers on the market today, this newly updated 5th Edition covers theory, hardware, instructions, programming, installation, startup, and troubleshooting in a way that makes it easy for you to understand and apply. New material has been added to explain communication networks, basic control signals, linear scaling of analog process signals, and Proportional Integral Derivative (PID) instructions used by many PLC applications. Supplementary programming examples utilizing the PLC instructions in the book impart 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.
The programmable logic controller, first introduced in 1969, has become an unqualified success. These computer-based devices have become the industry standard, replacing the hard-wired electromechanical devices and circuits that had controlled the process machines and driven equipment of industry in the past.
Many electricians and technicians are apprehensive about PLCs and their application in industry. Technician's Guide to Programmable Logic Controllers will explain PLC basics using easy-to-understand approach so that even with no experience with PLC you will be more comfortable with your first exposure to programmable logic controllers.
Gain additional knowledge with new chapters.
- Understanding Communication Networks, explains network principals, categories, construction, access, and protocols.
- Process Control Signals, Scaling, and PID Instruction, covers basic process control signals and linear scaling of analog process signals, as well as the Scale, Scale with Parameters, and Proportional Integral Derivative (PID) instructions.
Key Features:
- New and expanded material will help readers understand the various communication schemes that are used to pass, or exchange information, between the programmable logic controllers and the various control components and control systems.
- The new 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.
- Provides detailed programming information and examples on both the Allen-Bradley SLC-500 and the MicroLogix family of programmable logic controllers.
- Numerous and varied troubleshooting techniques round out the all-inclusive introduction to programmable logic controller installation, programming, and maintenance.
