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

edgeGate enables efficient and secure data integration into higher-level management systems such as ERP, MES, or SCADA. The gateway supports the connection to PLC and CNC controllers and utilizes the OPC UA standard, allowing for simple and flexible networking of both new and existing plants.

In addition, edgeGate offers MQTT Publisher/Subscriber functionality, enabling the direct integration of machine data into private or public IoT cloud applications on the IT side. The generic MQTT implementation supports the use of a wide variety of cloud providers. Like the OPC UA standard, MQTT also supports various security mechanisms, including encrypted connections, certificates, and user authentication, ensuring a high level of data security.

The edgeGate device includes three central functions designed to optimize security and performance in industrial applications: device management, license management, and a communication interface.

With these capabilities, edgeGate is a compact, secure, and future-oriented gateway for data integration.

Access to existing PLC and CNC controller data

• Supports up to 20 connections for access to Simatic Siemens PLC, Allen-Bradley PLC, Siemens Sinumerik controllers, Fanuc CNC controller, Modbus TCP controller, or OPC UA 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 data access 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).
