An optimal OPC UA server for Modbus, connecting and managing Modbus source data through the OPC UA server interface.
The Modbus MDB Adapter is the Modbus-specific module within the Matrikon Data Broker (MDB) adapter family, providing secure OPC UA connectivity to Modbus devices, PLCs and field RTUs. It offers robust options for accessing and managing Modbus source data through an OPC UA server interface, with support for all major Modbus variants used by PLCs and RTUs. Advanced scheduling for large field-based RTU deployments and channel redundancy are built in, and it runs as a Windows application or as a Linux container.
Bringing the Modbus equipment still installed everywhere up to a modern standard.
Exposes Modbus source data as an OPC UA server so higher-level systems can reach it through standard means.
Runs as a Matrikon Data Broker adapter, so it is managed alongside other protocol adapters within one configuration.
Channel redundancy for maximum reliability keeps data collection running when a communication path fails.
Advanced scheduling functionality for large, field-based RTU deployments keeps communication load manageable at scale.
Supports both Modbus Master and Modbus Slave modes, and adds meaningful context to raw Modbus data.
Modernizes existing Modbus infrastructure with OPC UA-based security and data context, enabling enterprise-wide visibility.
