If your usual tools are the Arduino and the Raspberry Pi, you might find it surprising that the industrial world tends to run on Programmable Logic Controllers, or PLCs. You can think of a PLC as a ...

The most common way to program early PLCs was using so-called ladder logic programming. Basically, a ladder logic diagram was a graphical way of representing the functions in a typical PLC and the ...

On the surface, a programmable logic controller (PLC) might seem like nothing more than a generic microcontroller, perhaps outfitted to operate in industrial settings with things like high ...

When a PLC is used primarily to replace relays, timers, and counters, it's hard to beat the simplicity and usefulness of ladder diagram programming. Their ability to accept programming in ladder ...

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 ...

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 ...

This article is one in an ongoing series about programmable logic controllers and their applications in broadcasting. You can read past articles online at radiomagonline.com. In the last article, we ...

PLCs (programmable logic controllers) are the control hubs for a wide variety of automated systems and processes. They contain multiple inputs and outputs that use transistors and other circuitry to ...

Programmable logic controllers (PLCs) are used extensively throughout the world. Over time, they have advanced to become more user-friendly, efficient, smaller, and less expensive. Different types of ...
