Expose the Unified Namespace to external clients, AI systems, and other FrameworX solutions.
Modules → Data Foundation → Data Services | Reference
Overview
FrameworX includes built-in services that expose your Unified Namespace (UNS) to external systems. These services run alongside your solution and provide standardized access to live data without additional infrastructure.
| Service | Protocol | Purpose |
|---|---|---|
| OPC UA Server | OPC UA | Expose UNS to enterprise systems and other SCADA platforms |
| MQTT Broker | MQTT | Publish/subscribe access for IoT devices and cloud platforms |
| MCP for Runtime | MCP | Enable AI/LLM models to query live solution data |
| DataHub Service | TCP | Synchronize data between multiple FrameworX solutions |
| TagProvider Services | Various | Allows UNS to dynamically queries tag definitions from external systesms |
Configuration: Built-in services are configured in Unified Namespace → TagProvider Services.
OPC UA Server
Expose your UNS to external OPC UA clients using industry-standard protocols.
Capabilities
- Browse and subscribe to any tag in the UNS
- Read/write access with configurable security
- Historical data access (if Historian configured)
- Alarm and event subscriptions
Configuration
Navigate to Unified Namespace → TagProvider Services and click the OPC UA Server icon.
| Setting | Description |
|---|---|
| Port | Default: 4840 |
| Security Mode | None, Sign, SignAndEncrypt |
| User Authentication | Anonymous, Username/Password, Certificate |
→ See OPC UA Server Reference for complete configuration
MQTT Broker
Built-in MQTT broker for publish/subscribe messaging without external infrastructure.
Capabilities
- Full MQTT 3.1.1 and MQTT 5.0 support
- Sparkplug B compatibility
- Topic-to-tag mapping
- QoS 0, 1, and 2 support
- WebSocket transport option
Configuration
Navigate to Unified Namespace → TagProvider Services and click the MQTT Broker icon.
| Setting | Description |
|---|---|
| TCP Port | Default: 1883 |
| WebSocket Port | Default: 8083 |
| Authentication | Anonymous, Username/Password |
| TLS | Optional encryption |
→ See MQTT Broker Reference for complete configuration
MCP for Runtime
Enable AI language models to query live solution data through Model Context Protocol.
Capabilities
- Query tag values from the UNS
- Retrieve alarm status and history
- Access historian data for trend analysis
- Extend with custom tools via Script Classes

Built-in Tools
| Tool | Description |
|---|---|
| Get Value | Read current tag values |
| Get Historian | Query historical data |
| Get Alarms | Retrieve alarm status |
Custom Tools
Create solution-specific tools using Script Classes. AI models can invoke any method you expose.

DataHub Service
Distributed data aggregation for multi-solution architectures. Enables multiple FrameworX solutions to share and access tag, device, server, and alarm namespaces.
Capabilities
- Multi-solution data synchronization
- Centralized UI solution consuming data from multiple edge solutions
- Shared alarm management across solutions
- Scalable distributed architecture
