OPC UA aggregation Server with full range of OPC UA Security Features

Secure Integration Server (SIS) provides a powerful OPC UA data integration layer. Based on the OPC UA aggregation server users implement flexible solutions combining the various OPC UA Servers at automation level with their associated address spaces and making the data available to IT applications via a consistent OPC UA interface. Secure Integration Server covers the full range of OPC UA security features and enables the implementation of state-of-the-art security solutions.

The interface abstraction of Secure Integration Server enables continuous adaptation and scaling of OPC UA-based IoT solutions throughout their entire lifecycle. Users gain a high degree of flexibility and at the same time significantly reduce integration and configuration costs.

Secure OPC UA Communication

• Support of all safety functions of OPC UA standard
• Provide different data for different users and applications
• Support for multiple OPC UA Endpoints (client or server), each with its own certificates
• Filtered access, depending on IP address (White List / Black List for OPC UA Endpoints)
• Detection of DoS (Denial of Service) attacks on OPC UA authentication

Data Aggregation

• Aggregation of data from multiple sources in a server (aggregation of OPC UA Namespace)
• Application access to aggregation servers, not too many individual data sources
• Extensive and flexible OPC UA Service-based address space filtering, down to OPC UA Item level
• Reduced configuration effort (Configuration not required individually for each OPC UA data source and each OPC UA Client)

Uniform Address Space for standardized Data Provision

• Common, stable OPC UA interface for different IT applications
• Creation of local address spaces for easy data exchange between OPC UA clients
• OPC UA address space modeling for mapping and organizing underlying data into information models based on industry standards (companion standards)
• Flexible mapping of variables of integrated OPC UA servers to various self-generated or loaded address spaces (Address Space Mapping)

MQTT Gateway for the Integration of OPC UA Applications into Modern Industry 4.0 or IoT Cloud Solutions

• Individual use of all security mechanisms of the MQTT standard, e.g. SSL encryption including certificates
• Protection against data loss through the Store&Forward function: data buffering when the connection is lost and automatic transmission after the connection reactivation
• Extensive and flexible trigger options through “LUA Script Engine” support
• Freely definable and customizable JSON data format
