Omron PLC Node-RED Serial Communication

PLC manufacturers 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 can read and write to the Omron controller using special protocol commands. We will connect Node-RED to the Omron CP1H PLC. A serial RS485 interface will be used for communication with the industrial controller. We will demonstrate reading and writing using Host Link (C-mode commands) to the Omron PLC. Let’s get started. More information can be obtained at our website.

Here are just a few. - Built on top of the most dependable programming language, JavaScript. - JavaScript is flexible and easy to work with on web browsers, server-side, IoT, IIoT projects, and more. - Visual flow type interface making programming easy. - Node will allow JavaScript code to run directly on a computer. - Node-RED is a free, open-source logic engine. - Connect to PLC, PAC, Temperature Controllers, and Process Controllers using standard protocols. - Save and read from databases - Easily make the Internet of Things (IoT, IIoT) industrial solutions. Node-RED provides the ability for you to quickly create custom control solutions. https://accautomation.ca/
