OPC UA Server & MQTT Publisher Gateway for Modbus TCP Controllers

Access Modbus PLC Data & integrate data with OPC UA into higher level management systems

uaGate MB is a gateway for Modbus TCP controllers, for example from Schneider Electric, Wago, Beckhoff or Phoenix Contact. Many other manufacturers also offer Modbus TCP as an open communication interface. 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.

Overview

Access to Data in Modbus PLCs from OPC UA Applications

  • Read and write access to Modbus controllers, e.g. from Schneider Electric, Wago, Beckhoff, Phoenix Contact, etc.
  • Integration of higher-level management systems like ERP, MES or SCADA using integrated OPC UA Server providing open, platform-independent, and market-proven communication
  • Easy local and global access to field data and routing through firewalls
  • Especially dedicated to retrofit upgrades, thus protecting former investments
  • No need for software updates, operating system patches and PC updates resulting in years of failure-free operation
  • Minimal PLC programming for register setup required
  • No dedicated PC required

PLC Project Data Available for Further Processing

  • Symbol import from user-edited text file
  • Easy setup of OPC UA Server requiring only a few steps for accessing data in Modbus PLCs
  • Web-based interface for gateway configuration

Industry-proven Security

  • 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 authentication
  • Security supported for MQTT communication with private and public clouds
