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 ...

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 ...

The PuffinPLC Project is an effort to produce a Linux-based GNU Public Licensed Programmable Logic Controller (PLC). PLCs were developed in the 1960s to replace the complex electrical relay circuits ...

STÄUBLI TEC-SYSTEMS is launching the uniVAL pi software that will allow robot programming to be implemented via the PLC, using Plug & Play in Siemens TIA Portal. Thanks to this optionally available ...

This paper attempts a journey right from configuring a PLC, writing application program to code generation along with run-time configurations and RTOS abstraction for embedding it into PLC hardware ...

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 ...

Embedded processors handle the rising complexity of automation tasks by employing architectures that are quite different from those of programmable-logic controllers. It is no secret that ...

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 ...
