Programmable Logic Controllers

An easy-to-read alternative to the expensive and jargon-filled manual sets, this reference describes how to set up and troubleshoot a PLC in general, and covers implementation in specific leading proprietary PLC systems: Allen-Bradley (PLC-5 and SLC 500), Siemens (Simatic S5 and Simatic S7), and OMRON (all, but specifically CQM1). It includes, but goes beyond, simple Boolean logic enabling readers to use all of the power of a modern PLC. Complete coverage of capabilities of modern PLCs; extensive troubleshooting coverage; full instructions (for Boolean logic, timing and counting, data manipulation, process control, and communication) -- with at least one instruction of each type described in detail and similar instructions described in terms of what they do differently; setup and configuration requirements of all PLCs. For anyone interested in programming and configuration of Programmable Logic Controllers (PLCs) for industrial control.
