Hailed as the most comprehensive introduction to PLCs on the market today, this newly updated 5th Edition 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 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.
- New and expanded material will 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 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 PLCs
- Numerous and varied troubleshooting techniques round out the all-inclusive introduction to PLC installation, programming, and maintenance
