This article describes the programming language ladder logic used to program PLCs and shows examples of how it functions. Ladder diagram, better known as ladder logic, is a programming language used to program PLCs (programmable logic controllers). This article will briefly describe what ladder logic is and go over some examples of how it functions. … Read more
What is a PLC? This article will lay out a succinct definition of a programmable logic controller and explain its basic components. The programmable logic controller, or PLC, is ubiquitous in every kind of process and manufacturing industry today. PLCs were initially designed to replace electromechanical relay systems in order to offer a simpler solution … Read more
Detecting objects is the first field-level task that must be considered before any feedback-based control can happen. Choosing from among the nearly unlimited proximity sensors can be challenging! In a perfect manufacturing world, you could always rely on your product or process to be in the right position at the right time, every time, all … Read more
Learn how to set up Ethernet/IP communications, including steps for both the FANUC controller and the Studio 5000 environment for a Rockwell PLC. Connecting a PLC to a FANUC robot via Ethernet/IP offers numerous benefits for industrial automation. It gives access to integrated control, allowing coordination between different manufacturing process components. The PLC can send … Read more
Coil, field winding, rotor, stator, eddy current… When it comes to motors, there are numerous terms that describe the theory of operation, but what is inside a 3-phase motor? Take a look, and learn how they work. One of the most common devices to find inside any industrial operation is the 3-phase induction motor. These … Read more
AC motors are common throughout industry – easily controlled by VFDs and without the maintenance that comes with DC brushes. So then, why are DC motors still used in certain applications? Direct Current (DC) Motors All motors work on the principle of switching magnet forces to rotate a shaft. A DC motor uses direct current … Read more
A brief overview of controllers through history and an analysis of factors to consider when deciding which one to use. A Historical Context PLCs were initially introduced in the 1960s and early 1970s. The goal back then was to replace relay switch cabinets and large masses of wires with a more compact and efficient solution. Later … Read more
There are multiple methods for mapping inputs and outputs to an industrial robot. In this article, we cover two of the most popular methods: letting the robot or the PLC control the I/O signals. There is one unavoidable question to ask during your next robotic design, no matter what brand of robot is used: you … Read more
In this article, we take a look at hydraulic, pneumatic, and electric actuators and how they are used in different scenarios. Actuators are key in automating processes as they convert energy into a form of mechanical motion. What types of actuators are available to engineers and when should they be used? What is an Actuator? Generally speaking, an actuator … Read more
PID controllers are an excellent method of using feedback to turn an otherwise open-loop system into one which can follow a carefully prescribed profile, correcting for inconsistencies caused by the equipment, the environment, and even the products in the manufacturing process. In many systems, it is sufficient to send voltage to a motor or valve, … Read more
