Node-RED Modbus TCP Handling Communication Errors

Node-RED Modbus TCP can recover from communication errors automatically. Options are available to you the programmer to continue the Node-RED flow upon detection of these errors.
Broken Ethernet cable, Modbus Server power, and Node-RED Client offline are just a few of the errors that can occur on the industrial plant floor. Our Node-RED program must account for and be tested for each of these conditions.
We will be communicating Modbus TCP (Ethernet) to our Click Plus PLC. Using the catch node we will detect and display errors that may occur. 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.
