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 ...

David Greenfield: Welcome to the Automation World Gets Your Questions Answered podcast, where we connect with industry experts to get the answers you need about industrial automation technologies. And ...

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 ...

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 ...

Modern industrial automation owes much of its flexibility to programmable logic controllers. Before programmable logic controllers (PLCs) appeared in the 1970s, factory control was dominated by ...

According to the IEC 61131-3 standard, there is a difference between a function and a function block in PLC programming. The main difference involves internal memory. So for instance, a function can ...

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 ...
