Peripherals: Tools and Devices for Efficient PLC Programming

December 19, 2024

PLCs are designed to run application programs – the programs controlling industrial equipment or processes – quickly and consistently. But how do you write, install and update such a program? That’s where programming terminals come in.

If the PLC is the brain behind industrial automation, the Input and Output module (or I/O module) is the central nervous system.

It wasn’t that long ago that treating wastewater and delivering clean, safe drinking water to homes relied on manual processes. Today, water treatment is largely automated, thanks in no small part to the use of Programmable Logic Controllers (PLCs) and other electrical devices that can be programmed to complete many of the tasks required with little to no human oversight.

The Difference Between PLC and RTU

November 14, 2022

It’s safe to say that we all benefit from process automation in some shape or form, whether we realize it or not. Many of the products and systems that we rely upon to feed our families, get us to and from work, and allow for a restful Sunday afternoon are made possible by process automation. More often than not, the devices that drive these processes will either be a Programmable Logic Controller (PLC) or a Remote Terminal Unit (RTU).

Variable Frequency Drives: Basics and Common Applications of VFDs

September 01, 2022

Electric motors are used in multiple applications of our everyday lives but require the right amount of electrical energy to provide optimal torque and speed. To control these motors, Variable Frequency Devices (VFD), are used to convert AC current into DC current from the power supply. In this article we will look at how these devices work, and how they are important

Important Differences between PLC and DCS

May 17, 2022

One of the most common questions in industrial control and automation systems is “what’s the difference between a PLC and a DCS? In order to fully understand the difference between these two systems, we must look at the history of Programmable Logic Controllers (PLC) and Distributed Control Systems (DCS), and break down their internal components.

Discrete vs. Analog I/O: What's the Difference?

December 01, 2021

When it comes to learning the foundations of PLC programming, it can be as easy as flicking on and off a switch. That’s the main difference between discrete and analog I/O modules! Discrete signals are simply on or off, whereas analog signals vary.

SCADA System: What is it and How it Works

November 18, 2021

When we think about technologies which have revolutionized industrial automation, we often think about a specific piece of hardware we interact with, rather than the software behind the scenes. For factories and manufacturing plants, the Programmable Logic Controller (PLC) dramatically improves efficiency and control; yet it’s the SCADA software which runs all the operations smoothly.
