OPC UA Server & MQTT Publisher Gateway for Modbus TCP Controllers

OPC UA Server & MQTT Publisher Gateway for Modbus TCP Controllers

uaGate MB is a gateway for Modbus TCP controllers. The gateway has an integrated OPC UA server for simple and secure data connection of new and existing systems to higher-level management systems, such as ERP, MES or SCADA systems.

In addition, uaGate MB also offers MQTT Publisher functionality, enabling direct integration of PLC data into private or public IoT cloud applications on the IT side. The generic MQTT implementation supports the use of a large number of different cloud providers. Similar to the OPC UA standard, MQTT also supports various security mechanisms such as encrypted connections, certificates and user authentication, thus contributing to a high level of data security.

With this functionality, uaGate MB is a compact, secure, future-oriented and proven gateway for data integration.

  • Read and write access to Modbus controllers
  • Integration of higher-level management systems using integrated OPC UA Server
  • Easy setup of OPC UA Server requiring only a few steps for accessing data in Modbus PLCs
  • Web-based interface for gateway configuration
  • Physically separated interfaces and separate configuration rights for OT and IT networks preventing intrusions
  • Supporting security standards as SSL/TLS and X.509 certificates
  • OPC UA compliant data encryption and user authentification
  • Security supported for MQTT communication with private and public clouds
