Matrikon OPC UA Data Broker Adapters: Industrial Protocol Connectivity Solutions

Matrikon Data Broker Adapter architecture diagram showing OPC UA connectivity between industrial protocols and enterprise systems

OPC UA-based Matrikon Data Broker Adapters (MDBAs) provide secure connectivity between Operational Technology (OT) data sources and enterprise IT systems. MDBAs connect industrial protocols including Modbus, PROFINET, Ethernet/IP, and Siemens devices to OPC UA servers. These adapters enable real-time data access across firewalls while maintaining OT network security standards.

MDBAs function as OPC UA translation layers between industrial data sources and enterprise applications. Each adapter converts native protocol data (Modbus registers, PROFINET I/O, Ethernet/IP tags) into standardized OPC UA information models. This protocol translation reduces integration complexity from dozens of proprietary connections to a single OPC UA interface standard.

The following MDB Adapters are available

: Request custom OPC UA adapter development for proprietary protocols

: OPC UA Adapter Benefits: Simplified Integration and Scalable Architecture

Direct Protocol Connectivity: Modbus, PROFINET, Ethernet/IP, and Siemens PLCs

MDBAs connect directly to industrial protocols without requiring proprietary middleware. Current adapters support Modbus TCP/RTU, PROFINET IO devices, Ethernet/IP controllers, Siemens S7 PLCs, and legacy OPC DA/AE servers.

MDBAs transform raw protocol data into operational OPC UA information accessible enterprise-wide.

With MDBAs, your data is not just accessible; it is fully operational.

Part of the MDB enterprise solution, MDBAs give you access to advanced features like:

OPC UA Reverse Connect enables secure data transmission from OT networks to IT systems without inbound firewall rules
Standardized information models implement OPC UA Companion Specifications for PLCopen, PackML, Euromap, and ISA-95 integration
MQTT Publisher extension transmits OPC UA data to AWS IoT Core, Azure IoT Hub, and Google Cloud IoT
Data aggregation, historical buffering, and real-time alarm notification across all connected data sources

Scalable OPC UA Architecture: Volume Growth, Security Standards, and API Extensibility

MDBAs scale from single-site deployments to enterprise architectures supporting 10,000+ data points per adapter. The modular MDB architecture accommodates data volume increases, evolving cybersecurity requirements (IEC 62443, ISA/IEC 62443), and new protocol demands. Organizations add capacity by deploying additional MDBA instances without architectural redesign.

horizontal scaling from hundreds to hundreds of thousands of data points per deployment,
compliance updates for evolving IEC 62443, NIST, and NERC CIP security requirements,
additional protocol support through MDBA API custom adapter development

Organizations extend MDBA functionality through the MDBA API to create custom protocol adapters. The API provides C++ and .NET interfaces for developing adapters that integrate proprietary protocols into the standard OPC UA framework. Custom adapters inherit core MDB features including security, buffering, and cloud publishing capabilities.

Download evaluation versions of Modbus, PROFINET, Ethernet/IP, Siemens, or OPC DA/AE to OPC UA adapters to test connectivity in your environment.

Matrikon OPC UA adapters provide standardized connectivity for industrial automation protocols across enterprise IT and OT networks.
