PLC Industrial Automation

PLC & Industrial Automation is a practical, systems-first guide built around understanding, verification, and recovery rather than unexplained recipes. The Second Edition combines a coordinated N9LYA visual system, eight instructional diagrams and a practical control narrative, i/o, interlocks, safety, commissioning, and change control worksheet.  Readers are shown how to establish intent, recognize boundaries, test the real system, preserve evidence, and leave a recoverable handoff. Version-sensitive details must be checked against current primary documentation before use.
