What is Ladder Logic?

If you are involved in any way with industrial machinery, you almost have to have heard of ladder logic. Since there are almost never ladders involved, it probably doesn’t make a lot of sense that we call it that, but the reasons for the name are buried in the history...

What Is a Safety Instrumented System?

   In this video and blog post, you will learn what a Safety Instrumented System is, how it is constructed, and how it plays an important role in keeping our chemical, refining, and other manufacturing plants running safely and as productive community partners and...

PLC Basics | Programmable Logic Controller

   Today we are going to talk about PLC basics. The programmable logic controller, or PLC, is a special purpose computer. It has no display, no keyboard, no printer, no hard drive, and hides in the control panel out on the factory floor, but it is still a...

What is the difference between SCADA and HMI?

Today, you will learn the difference between SCADA and HMI. We will talk about the differences as well as the similarities, and also when each is used. There is usually some confusion because of the similarities.So let’s dive in to SCADA for now. SCADA stands for...

What is the Difference Between PLC and DCS?

In a nutshell, a PLC or programmable logic controller is a ruggedized computer used for automating processes. A DCS or distributed control system is similar to a PLC in that it has rugged computer controllers however the DCS contains multiple autonomous controllers...

What Are the Advantages PLCs Have over Relay Systems

There are many advantages that a PLC system holds over a relay system. Today, we will dive into some of those advantages. One of the first and simplest advantages is reliability.   1. Reliability The internal relay systems of a PLC are solid state. This means that the...

What is a Stepper Motor and How it Works?

In this lesson we will discuss what a stepper motor is and how it works, so let’s first determine what a stepper motor is and examine some unique features of a stepper motor. Have you ever thought about how a robotic arm moves with precision or how graphic printers...

Types of Sensors

In this article, we are going to familiarize you with the types of sensors that we frequently use in industrial equipment. We intend this to be an introductory video for a new engineer just getting started, or for anyone looking for a general understanding of some...

What is HART Protocol?

In this article, you will learn what a HART protocol is, how HART is used with analog sensors, how a HART analog sensor works, and what advantages a HART analog sensor can give your operation. Current-loop technology has been used for analog sensors for the past 4...

How to Wire Discrete DC Sensors to PLC – Part 2

In this blog post, you will learn how to wire a 3-wire DC sensor, like an inductive proximity sensor, to a PLC input card. You will also learn what a 3-Wire Discrete sensor is and recognize some of the common types of 3-Wire Discrete sensors. DC sensors can be used to...

What is the Automation Pyramid

Today, I will try to teach you about the Automation Pyramid. More specifically, the devices used to make up the automation pyramid. So what exactly is the automation pyramid? It is a pictorial example of the different levels of automation in a factory or industry. It...
