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 ...

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 ...

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 ...

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 ...

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 ...

Continuing with our series of articles exploring the future of automation, we peek this month at controllers and IPCs. The newest versions are smarter, faster, smaller and easier to use. If you’re ...

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 ...
