Node-RED Integration

Description

The Node-RED screen in Nodum ENTERPRISE allows for native integration with this powerful visual programming tool. Node-RED becomes the engine for data transformation and enrichment, allowing you to create logical flows to clean, calculate, contextualize, and redirect information coming from your EDGE devices.

The system uses the MQTT protocol to communicate data from the UNS to Node-RED. For the integration to work, it is essential that you have previously defined the output variables within your UNS. Without these variables, Node-RED will not know what data to listen for. In this way, Nodum combines the power of a unified data structure (UNS) with the flexibility of Node-RED to perform advanced transformations.

Main Functionality

• Visualization and management of Node-RED flows integrated with Nodum.
• Sending industrial data to Node-RED using MQTT as the communication protocol.
• Interaction with nodes and processes configured in Node-RED.
• Validation of the existence of output variables in the UNS before allowing integration.
• Real-time monitoring of the status and results of the flows.
