Programmable logic controllers (PLCs) have become the most popular and efficient way to control manufacturing equipment. Replacing the older style of hard-wired control relays, PLCs can be configured ...

If your usual tools are the Arduino and the Raspberry Pi, you might find it surprising that the industrial world tends to run on Programmable Logic Controllers, or PLCs. You can think of a PLC as a ...

In most industrial plants, it's not uncommon to have programmable logic controllers (PLCs) from different suppliers, often on the same production line. Each PLC may come with a different communication ...

Basic Programming for PLCs provides an overview of the basic principles, structure, and instructions of PLC programming. Most PLC programs use instructions written in ladder logic, which is a ...

In Part 1 of this two-part series, we explored PLC basics and voltage sag susceptibilities. In this segment, we present PLC voltage sag test results along with guidelines for making PLC systems more ...

This file type includes high-resolution graphics and schematics when applicable. Historically, motion controllers, programmable logic controllers (PLCs), and industrial personal computers (PCs), which ...
