opcda-bridge-gateway
Windows gateway that exposes native OPC DA (COM/DCOM) servers over the network to
opcda-bridge-client and other gRPC clients.
Install it with Cargo on a Windows host:
The gateway must run on the Windows machine hosting the OPC DA server. See the repository README for service installation, configuration, and firewall setup.
Tag browsing uses native one-level OPC DA enumeration with bounded pages. The gateway owns opaque browse sessions and continuation tokens, preserves exact ItemIDs separately from display names, and reports whether a page is complete. Namespace search is a bounded progressive operation that can be cancelled by dropping the client stream.
