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 ...

A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines. 1. The image above is ...

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 ...

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 ...

These small controllers deliver cost savings and many advantages over traditional methods of control. Seems like everything is getting smaller-cheaper-faster these days. So why not go smaller while ...

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 ...

THE use of function blocks for programming of programmable logic controllers (PLCs) is gaining wider acceptance. Rather than the classic “contact and coil” representation of ladder diagram or relay ...

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 ...
