OPCUA Modeler by Sterfive
The Fluent Way to build OPC UA Models
Use our powerful DSL (Domain Specific Language) in YAML to create advanced OPC UA Models.
OPC UA modeler is based on NodeOPCUA by Sterfive.
Go from idea to compliant NodeSet in minutes. Leverage our intuitive low-code YAML syntax directly within Visual Studio Code and accelerate your Industry 4.0 development.
The story of OPCUA Modeler
A Modeler built for OPC UA Sytem Architect,by Node-OPCUA Core Experts
As core maintainers of
node-opcua
, we've seen where the friction lies. We didn't build another graphical tool to pull you out of your workflow. We brought the modeling process to you, directly into Visual Studio Code. This is modeling reimagined—fast, fluent, and perfectly integrated.

Accelerate Your OPC UA Development
OPCUA Modeler is designed to streamline the process of creating and managing OPC UA information models, making it easier for developers to build robust industrial IoT applications. By providing a low-code solution, it reduces the complexity and time required to develop compliant OPC UA models.Smart Manufacturing
Build Your Digital Twin Foundation
Standardize data from PLCs, robots, and sensors to create a high-fidelity, interoperable digital twin of your entire production line.
In Industry 4.0, a digital twin is essential for simulation, optimization, and predictive analysis. *
A structured OPC UA model provides the semantic backbone for this twin.
By using a modeling tool to define standard asset models for your machinery (e.g., CNC machines, conveyors, robotic arms), you ensure that data from disparate vendors is ingested with consistent meaning and context.
This allows you to accurately simulate process changes, predict failures before they occur, and optimize production flow with a clear, holistic view of your entire factory floor, breaking down data silos.
Energy & Utilities
Accelerate Smart Grid Interoperability
Rapidly model Distributed Energy Resources (DERs) like solar, wind, and batteries for seamless grid integration, monitoring, and control.
The modern energy grid is a complex network of traditional sources and new Distributed Energy Resources (DERs). Achieving stability and efficiency requires seamless, secure communication. Using a standardized modeling approach with OPC UA (often aligned with standards like IEC 61850) is critical. Our modeler allows you to rapidly define and deploy consistent models for solar inverters, battery storage systems (BESS), and charging stations, ensuring they can be monitored and controlled in a unified, vendor-agnostic way. This accelerates the transition to a smarter, more resilient, and secure energy grid.
Pharmaceuticals & Life Sciences
Enforce Compliance and Data Integrity
Create robust models for batch recipes and equipment that enforce data integrity and provide a clear audit trail to support 21 CFR Part 11 compliance.
In the pharmaceutical industry, data integrity and traceability are non-negotiable. An OPC UA model provides the framework for a comprehensive electronic batch record (EBR). With a dedicated modeler, you can define the entire manufacturing process, from raw material inputs to critical process parameters (CPPs) and quality attributes (CQAs). By enforcing standardized data structures, types, and contexts at the source, you create an immutable audit trail, simplify the validation process, and build a system that inherently supports the strict compliance requirements of regulatory bodies like the FDA.
Logistics & Automated Warehousing
Unify Warehouse Automation Systems
Integrate Autonomous Guided Vehicles (AGVs), robotic arms, and warehouse management systems (WMS) into a single, cohesive operational model.
A modern warehouse is a symphony of automated systems, often from different manufacturers. To achieve peak efficiency, they must work in concert. A structured OPC UA model acts as the conductor. Use a modeler to define standard interfaces for AGVs, conveyor systems, and robotic picking arms based on specifications like VDA 5050. This allows your central Warehouse Management System (WMS) to communicate with all assets using a single, unified language, enabling real-time optimization of material flow, drastically reducing integration costs, and creating a truly interoperable and scalable automation ecosystem.

Start Building Your OPC UA Models Today
Download and install the OPCUA Modeler from our official website or GitHub repository.
Start a new project in the modeler and define your namespace, objects, and variables.
Generate your model using the low-code YAML syntax. Add nodes, set properties, and define relationships between objects.
Validate your model, then export it as a NodeSet XML file for use in your OPC UA server.
Example Use Case
Suppose you want to model a simple temperature sensor:
- Create an
ObjectType
calledTemperatureSensor
. - Add a
Variable
node for the temperature value. - Define methods for calibration or diagnostics.
