ACC Automation: PLC & Industrial Control Learning
Practical Tips and Techniques
A human-machine interface (HMI) is present in some form for every PLC. The HMI connects a user to a machine system to exchange information or control data. This interaction with the system can be through hardware or software. HMIs offer different people information and control in many ways for the automated system. Operators, supervisors, mechanics, … Read more
The Productivity 2000 series of programmable logic controllers has a slim DIN rail density form factor. This means that this micro-modular PLC can have a power supply, CPU, and seven IO modules in only 10-1/2 inches. Input and output cards can be installed, removed, or replaced without turning the power off to the PLC system. … Read more
Developing a programmable logic controller (PLC) program can be broken down into five steps. These programming steps are as follows: Five Steps to PLC Program Development Step 1 – Define the task Step 2 – Define the Inputs and Outputs Step 3 – Develop a logical sequence of operation Step 4 – Develop the PLC … Read more
PLC outputs are the next component of our PLC block diagram. The PLC program will control the outputs of the PLC. Controlling outputs is one way to get the inputs to change. We will be looking at digital and analog outputs that can be wired to the programmable logic controller. PLC troubleshooting outputs will also … Read more
PLC inputs are one component of our PLC block diagram. The output actions of the PLC will be controlled based on the inputs. We will be looking at digital and analog inputs that can be wired to the programmable logic controller. We will be looking at wiring of a normally open (NO) push button, normally … Read more
Many questions come from serial communications using the Click PLC. Most of these questions deal with communication timing when using multiple send-and-receive instructions. We will show you how to deal with serial communication timing in the Click PLC. Receive and Send instructions will allow you to send and receive serial data to an external device. … Read more
Invented in 1968 by Dick Morley, the programmable logic controller (PLC) is a simple rugged industrial computer. This free plc training series is designed for everyone to learn about these controllers. PLCs are constantly evolving and continue to be the best option for a variety of industrial automation applications. Even though the PLC is changing, … Read more
PLC manufactures have their own proprietary protocols. These methods of communication will allow you to program the controller. Other protocols will allow you to collect and log information from the programmable logic controller. Node-RED has the ability to read and write to the Omron controller using special protocol commands. We will connect Node-RED to the … Read more
An LCD (Liquid Crystal Display) is a great way to display information in our Arduino Uno controller. We will be wiring and programming an alphanumeric, two rows with 16 characters on each row. The display has an LED (Light Emitting Diode) backlight with adjustable contrast. This white and blue LCD will display “Hello World!” on … Read more
The IR (Infrared) remote control is a great way to incorporate wireless control of your project. Infrared receiver modules are simple and easy to use. In this post, we will be connecting the IR receiver to the UNO, and then use a Library that was designed for this particular sensor. In our sketch we will … Read more
