OPC UA Server & MQTT Publisher Gateway for PLC Controllers and CNC Machines

Access PLC, CNC, and OPC UA Data via MQTT and OPC UA for higher-level management applications

edgeGate makes data integration easier than ever before. The gateway supports the connection of PLC & CNC Controllers from and uses the OPC UA standard for a simple and secure data integration of new and existing plants in higher-level management systems, such as ERP, MES, or SCADA systems.

In addition, edgeGate also offers MQTT Publisher functionality, enabling direct integration of Machine data into private or public IoT cloud applications on the IT side. The generic MQTT implementation supports the use of many different cloud providers. Like 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.

Moreover, the functionality of edgeGate can be extended with the complete portfolio of our edgeConnectors and edgeAggregator solutions.

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


Access to existing PLC and CNC Controller Data

  • Read and write access to Simatic Siemens PLC, Allen-Bradley PLC, Siemens Sinumerik controller, Fanuc CNC controller, Modbus TCP, or OPC UA Client machine Data.
  • Easy local and global access to field data and routing through firewalls.
  • Protect investment through simple retrofit upgrades, as well as for modern controllers’ integration, without require modifying the running configuration in them.
  • No PLC programming or dedicated PC required.

Standardize and Simplify the Machine Data Integration

  • Integration of higher-level management systems like ERP, MES, or SCADA using integrated OPC UA Server providing open, platform-independent, and market-proven communication.
  • Simple data transmission to an MQTT broker using the MQTT publisher functionality for local or cloud-based solutions.
  • Separate Web interface for Gateway configuration and Access Data application to avoid misconfigurations.

Industry-proven Security

  • Physically separated interfaces for OT and IT networks add security layer to the plant.
  • Supporting security standards such as SSL/TLS and X.509 certificates.
  • Support of all security functions of OPC UA and MQTT.
  • Filtered access depending on IP address (Whitelist / Blacklist for OPC UA endpoints).
