OPC UA Gateway

Transparent interoperability between existing DDS and OPC UA applications.

⇠ All RTI LABS Projects

RTI-Labs-hero

What does it do?

OPC UA is a connectivity framework for industrial automation created by the OPC Foundation to expose information from OPC applications in a unified address space in a platform-independent manner.

In order to allow OPC applications and DDS™ applications to communicate with each other, RTI led a joint RFP submission at the Object Management Group® (OMG®) to standardize this capability.

The OPC UA/DDS Gateway follows a simple OPC UA Subscriptions to DDS mapping: Each OPC UA Subscription is mapped to a DDS Topic and each MonitoredItem is mapped to a member of the DDS Type associated with the DDS Topic.

Features & Benefits

  • Standalone gateway that allows OPC UA and DDS application to talk
  • Applications don't need to be modified to take advantage of the gateway
  • Supports the OMG standard
