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 ...

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 ...

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 ...

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 ...

The programmable logic controller (PLC) is a microprocessor-based system that accepts input data from switches and sensors, processes that data by making decisions in accordance with a stored program, ...

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 ...

For decades, Programmable Logic Controllers (PLCs) have been the go-to solution for safety systems across refineries, ...
