OPC UA for Node‑RED
The most comprehensive OPC UA package for Node‑RED. Enterprise-grade security, powerful templates, and the new Unified Message Structure system.
Powerful Template System
Start with battle-tested configurations - customize only what you need
Work Fast and Secure
The new template system of PLUS for Node‑RED gives you all the options while ensuring everything works right from the start.
Select a template like 'secured' for your client configuration and only set the endpoint to connect to. Your security policy is automatically configured to industry standards.
Enterprise-Grade Features
Everything you need for production OPC UA deployments
Security Modes
Support for None, Sign, and SignAndEncrypt with Basic128Rsa15, Basic256, and Basic256Sha256
Subscriptions
Event-driven data monitoring with configurable sampling intervals and deadband filters
Method Calls
Execute remote procedures with the new Method Call node featuring a visual method explorer
Address Space Browser
Visual node browser to explore and select nodes directly in the Node‑RED editor
Register Nodes
Optimize server resources with registered nodes for improved read/write performance
Client Control
Control client state within deployed flows - no more redeploys for connection issues
New Nodes in PLUS
Exclusive nodes that make the difference
Client Control Node
The biggest improvement to the OPC UA package is the Client Control node. It can control the client right inside a deployed flow!
No more re-deployment of flows because the client disconnected somehow and cannot reconnect. Take full control of your OPC UA connections.
Industry 4.0 Use Cases
Real-world applications powered by OPC UA and Node‑RED
PLC Integration
Connect Siemens S7, Beckhoff TwinCAT, or any OPC UA-enabled PLC to your Node‑RED flows for seamless machine control and monitoring.
Data Historian
Collect and aggregate machine data from multiple OPC UA servers. Transform and store in InfluxDB, TimescaleDB, or cloud platforms.
Edge-to-Cloud Gateway
Bridge your OPC UA infrastructure to MQTT, Kafka, or cloud IoT platforms. Use our Unified Message Structure for seamless data translation.
Predictive Maintenance
Monitor equipment health indicators via OPC UA subscriptions. Feed machine learning models for predictive analytics.
Remote Monitoring
Build custom dashboards for remote machine monitoring. Integrate with Node‑RED Dashboard or custom web applications.
Education & Training
Learn OPC UA fundamentals with visual, low-code programming. Perfect for technicians and engineers new to industrial protocols.
Unified Message Structure (UMS)
Protocol-agnostic data format for seamless integration
Bridge Any Protocol
The Unified Message Structure (UMS) is a standardized data format that works across all PLUS for Node‑RED packages.
Read OPC UA data and publish it directly to MQTT without complex transformations. UMS ensures consistent data structures regardless of the source protocol.
