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.
