ICONICS OPC XML-DA Wrapper is a middleware component that exposes classic OPC Data Access (OPC DA) servers as OPC XML-DA web services. It enables HTTP/SOAP-based connectivity so remote or web-based clients can browse tags, read and write real-time values, and subscribe to data changes without relying on DCOM. The wrapper translates data types, timestamps, and quality/status codes between OPC DA and XML-DA, helping integrate legacy HMI/SCADA systems with enterprise applications, custom clients, or cloud gateways.
Typical deployments install the wrapper on the same machine as the target OPC DA server and publish the XML-DA endpoint via IIS or a built-in host. Benefits include easier firewall traversal, reduced DCOM configuration complexity, and a standardized XML interface for interoperability. This tool is especially useful when you need to bridge older OPC DA systems to web-friendly interfaces while maintaining reliable, standards-based data exchange.
