Cogent DataHub FAQs

What Is Cogent Datahub Used For?

Cogent DataHub is a middleware that bridges the gap between OT (operational technology) and IT/cloud systems, making it a popular choice across industries like energy, manufacturing, and utilities.

Can Cogent DataHub Connect OPC UA and OPC DA Systems?

Yes. DataHub can operate as both an OPC UA server and client and can help bridge OPC UA with OPC Classic systems. This supports phased upgrades where legacy OPC DA equipment still needs to communicate with newer applications.

What Protocols and Systems Do Cogent Datahub Support?

Cogent DataHub uses open, industry-standard data protocols including OPC, MQTT, ODBC, Modbus, DDE, and TCP to provide a wide range of connectivity options. It also integrates live processes and connects SCADA systems, data lakes, and historians.

How Does Cogent Datahub Protect Operational Technology (OT) Networks From Cyber Threats?

The Cogent DataHub Tunnellers let you integrate your data without exposing your networks. With no DCOM hassles, no VPNs, and no inbound firewall ports into the operations network. Additionally, DataHub allows bidirectional transfers with industry-standard protocols in a transparent, secure, and reliable way without opening ports in the perimeter.

How Do I Know Which DataHub Modules I Need?

The right configuration depends on your protocols, sites, security model, historian or cloud targets, and whether you need redundancy or WebView. MAC Solutions can review your architecture and recommend a suitable DataHub package.
