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 ...

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 ...

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 ...

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 ...

This tutorial offers an in-depth introduction into programmable logic controllers (PLCs). The article starts with an overview of the history and the role PLCs in factory automation. The basic ...

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 ...

Stäubli has launched uniVAL pi , a software solution that will enable robot programming to be implemented in the future via the PLC, using Plug & Play in Siemens TIA Portal. A PLC, or programmable ...

Programmable logic controllers (PLCs) traditionally have been considered inherently insecure. But a new security initiative that outlines 20 best practices for coding the industrial computing device ...
