Omron PLC Node-RED Serial Communication

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 Omron CP1H PLC. A serial RS485 interface will be used for communication to the industrial controller. We will demonstrate reading and writing using Host Link (C-mode commands) to the Omron PLC. Let’s get started.

There are several reasons why we are using Node-RED. 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, 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.
