@Aiknow/iot-link-nodes

@Aiknow/iot-link-nodes is a Collection of Node-RED nodes tailored for C-LAB IoT-LINK industrial gateway. It provides a set of custom nodes that enables the user to directly access and manage the gateway.

Pre-requisites

The @Compulab IOT-LINK requires Node-RED to be installed as root to run correctly.

Install

To install the stable version use the Menu - Manage palette option and search for IOT-LINK, or run the following command in your Node-RED user directory - typically /root/.node-red :

npm i @aiknow/iot-link-nodes

Restart your Node-RED instance. The IOT-LINK nodes will appear in the palette, along with a new AIknow tab on the left panel.

Post-install

After installation the gateway will automatically be equipped with :

  • Necessary commands : if they are not already installed
  • Package scripts : correctly configured and all made executable
  • 2 services : for modem managing
  • Modbus Node-RED library : for handling RS485 communications

Modbus Library

The package includes node-red-contrib-modbus, an industry-standard library for Modbus protocol communications.

This library supports both client and server modes, handling TCP, Serial (RTU/ASCII), and Telnet connections for industrial automation and device control.

For detailed configuration options and examples, see the node-red-contrib-modbus documentation.
