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:

cargo install opcda-bridge-gateway

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 recursive branch/leaf enumeration for hierarchical OPC DA servers. The gateway preserves dotted and slash-separated item IDs so clients can expand namespaces such as FCS0201/Control/PV one level at a time.
