How to Master Modbus TCP Communication with Node-RED?

May 19, 2025
How to Master Modbus TCP Communication with Node-RED? We will now establish communication using Modbus TCP from the C2-NRED module to the Ethernet ports of the BRX Do-More and Click PLCs. Previously, we installed version 5.31.0 of the node-red-modbus-contrib package. We utilized the C2-NRED Package Compatibility Finder to locate and download this Node-RED package. Efficient PLC communication is essential for seamless operations. In this process, we will use the installed Modbus nodes to read 10 registers from the BRX Do-More PLC and write these values to the Click PLUS PLC. This will be done through the Ethernet port on the C2-NRED module. The C2-NRED Node-RED module is a versatile platform for integrating different systems and enhancing the overall efficiency of industrial setups. Let's get started. More information can be obtained at our website. This includes all of the links mentioned in this video. https://accautomation.ca/c2-nred-to-brx-do-more-click-plcs-modbus-tcp/ 00:00 C2-NRED to BRX Do-More & Click PLCs: Modbus TCP! 01:13 Setting up the BRX Do-More PLC 02:46 Node-RED C2-NRED Modbus Flow 04:22 C2-NRED Modbus TCP Flow to Read BRX Do-More PLC 07:39 Setting up the Click PLUS PLC 08:42 C2-NRED Modbus TCP Flow to Write to Click PLUS PLC Previously, we looked at the following using C2-NRED Node-RED: CLICK PLUS C2-NRED: Easy Install for PLC Module! https://accautomation.ca/click-plus-c2-nred-easy-install-for-plc-module/ https://youtu.be/ZFgcVwCYCRk Unleash Innovation: Node-RED Flow in Click PLC https://accautomation.ca/unleash-innovation-node-red-flow-in-click-plc/ https://youtu.be/JcFX6kK36p4 Master Node-Red C2-NRED Control of Click PLC I/O https://accautomation.ca/master-node-red-c2-nred-control-of-click-plc-i-o/ https://youtu.be/AGiDeqQ8PTg Click PLC & AEDES MQTT: What is the Big Deal? https://accautomation.ca/click-plc-aedes-mqtt-what-is-the-big-deal/ https://youtu.be/Ilb5IFqOrNo How to Use the Click PLC C2-NRED Package Finder https://accautomation.ca/how-to-use-the-click-plc-c2-nred-package-finder/ https://youtu.be/q9etRrsnQ9w CLICK PLCs were designed with simplicity in mind, providing reliable control at a low, low cost and with little to no learning curve. This simplicity makes CLICK a perfect solution for small machines, home automation projects, pneumatic applications or anywhere a simple system needs a budget-saving control solution. Building on the original CLICK s simple design, the new CLICK PLUS PLCs offer the same practical control but with some surprising bells and whistles. Using the same FREE, streamlined PLC programming software as its predecessor, the CLICK PLUS PLCs provide no-headache programming combined with advanced capabilities like Wi-Fi communication and data logging. The Click and Click PLUS PLC series can be found at this URL: https://accautomation.ca/series/click-plc/ Features of the new Click PLUS PLC (C2-0xCPU) includes the following: Micro USB DHCP support DNS support Wi-Fi (programming and Modbus TCP) Bluetooth (Wi-Fi) provisioning SD Card (Data Logging) Data Logger Network Time Service MQTT (Publish/Subscribe) Required PLC Password Disable Ports Strong Password Support Disable Ping Response Encrypted Password Transfer We are using the Click and Click PLUS PLCs for several reasons. Here are just a few. - Investment is low for the hardware, and the software is free - Standalone PLC with built-in I/O - Communication ability - Ethernet Port, RS232, RS485 - support for Modbus RTU, Modbus TCP, etc. - Ability to expand the system with various modules, including RTD and Thermocouple inputs directly.
