ibaHD-Server has an OPC UA server module, which provides a read interface.  An ibaHD-Server OPC UA Server+ license is required to use it. This enables data from timebased HD stores to be published as OPC UA objects.

Without this license, only status information can be queried. The status information can be seen under the HD Server Info node on the Tags tab. The data nodes cannot be changed.

Connected OPC UA clients can subscribe to signal data, i.e. receive current data cyclically, and also request historical data over a particular time range.

The OPC UA server supports multiple endpoints and different security and logon policies. For example, this means that OPC UA clients can connect to a particular ibaHD Server user.

OPC UA server communication is secured by certificates. The certificates are managed on the Certificates tab in the ibaHD Manager.

You can configure the OPC UA server settings on the OPC UA tab in the ibaHD Manager. The OPC UA tab contains status information, connection information, and the configuration.
