Integrate OPC UA and DA
Integrate OPC UA and DA

What it does

  • Connects OPC UA systems to OPC DA (Classic) systems.

    • Enables OPC DA clients to read from OPC UA servers.

    • Enables OPC UA clients to read from OPC DA servers.

  • Better, more flexible OPC UA tunnelling client.


Benefits

  • Includes both client and server interface for both UA and DA.

  • Maintains the OPC UA data model, while other gateways flatten it.

  • Automatic OPC DA / UA and UA / DA protocol conversions built-in. 

  • Automatically discovers all the points from the server.

  • Eliminates cache latency and stale data, so you always know the data quality and have the most current value

  • Multi-threaded interface means that a slow or non-responsive server will not slow down other connections


One key advantage of using the DataHub OPC Gateway is that the data model stays intact, unlike other UA/DA gateways.  The full data hierarchy from the OPC UA server gets faithfully represented in the OPC DA client.

Conveniently, the DataHub OPC Gateway can replace the client side of any OPC UA-based tunnelling solution. Doing so gives you convenient configuration options and a better replica of the original OPC DA server’s data hierarchy.


Automatic discovery

  • You don’t have to select all the points you want to read from the server, let the DataHub browse the whole data set.

  • This is more robust if the data set changes on the next run, the DataHub will figure it out.
