In part one of this series, we looked at the PLC’s internal architecture, briefly discussed Ladder Logic programming, Human-Machine Interfaces, advantages of the PLC’s ability to react consistently ...

Though PLC (programmable logic controller) programming languages may not receive the attention that general computing programming languages, such as JavaScript, C#, or Python do, they remain critical ...

Low-code and modular programming environments are transforming PLC programming, with vendors providing pre-packaged libraries and objects that eliminate traditional IEC-61131-3 style coding, allowing ...

A Programmable Logic Controller (PLC) is a specialized computing system widely used to control real-time industrial processes and assemblies. The block diagram of a generic PLC is shown in Figure 1.

An HVAC company in search of modern machine-control advantages finds an Arduino-compatible open PLC controller is the solution. Like many modern-day makers and hobbyists, I have always been inspired ...

This file type includes high-resolution graphics and schematics when applicable. Historically, motion controllers, programmable logic controllers (PLCs), and industrial personal computers (PCs), which ...

When learning ladder logic, I was told that some new PLC systems were moving to scripted programming languages. My instructor assured us that we would not need to know anything other than ladder logic ...
