If you're looking for this book, I can suggest some possible sources:

It won't teach you how to code an AI vision system, but it will teach you why your motor contactor won't turn on. For the fundamentals of industrial control, this update keeps a classic alive.

The CPU reads the input memory table and executes the user program (e.g., ladder logic) from the first rung to the last rung, updating the Output Status File based on the logic rules. If you're looking for this book, I can

Industrial applications require more than simple on/off combinations. PLCs utilize internal software instructions to perform advanced timing, counting, and data manipulation functions. Internal Timers

Mechanical relays wear out over time, leading to frequent downtime and difficult troubleshooting.

The PLC checks the physical state of every input device connected to its input modules. It records these states (0 for OFF, 1 for ON) into an internal memory table called the Input Status File. Phase 2: Program Execution Mechanical relays wear out over time, leading to

A hybrid between a traditional PLC and a standard PC, offering better memory, advanced processing capabilities, and native IT network integration.

The CPU is the brain of the controller. It executes the control program stored in its memory, performs arithmetic logic, and manages communication between components. 2. The Input/Output (I/O) System offering better memory

William Bolton's Programmable Logic Controllers (now in its 6th edition) is another strong contender.
