Frequently Asked Questions

Filter by Category

The OPC UA Universal Server is a centralized OPC UA server that aggregates data from multiple industrial and IT systems and exposes it through a standardized OPC UA interface for secure and reliable data access.

Connects seamlessly to a myriad of protocols, including:

  • Industrial Protocols: Modbus, OPC DA (64/32), OPC HDA, OPC AE, OPC UA, DNP, S7, Allen Bradley, IEC -104, BACnet, J1939, SNMP
  • IoT Protocols: MQTT, AMQP, REST
  • Data Stores: MS SQL, MySQL, Oracle, PostgreSQL, Mongo, FTP, Kafka, MS Access, CSV, Aveva PI, InfluxDB, ODBC

Yes. The OPC UA Universal Server can collect data from multiple OPC UA Servers and expose them to third party applications using a unified data model. In case the source OPC UA Servers are in the OT layer, the OPC UA Universal Server can be deployed on DMZ layer to act as an additional security layer and isolate the OT network.

Yes. The OPC UA Universal Server supports real-time data, historical data, alarms and status notifications, allowing clients to access operational data using standard OPC UA services. The OPC UA Universal Server provides a graphical user interface allowing users to configure their input tags, history tags as well as as alarms (high-high, high, low, low-low alarms)

The OPC UA Universal Server implements OPC UA security mechanisms, including secure communication, authentication, and user access control, to ensure reliable and protected data exchange between systems.

Yes. The OPC UA Universal Server is designed to integrate with existing industrial infrastructures and legacy systems, allowing organizations to modernize their architectures without replacing existing equipment.
