- Multiple connections - Gateway software should be able to connect to any number of data sources and provide the resulting data to any number of users.
- Integrated data set - Ideally, the data from any of the various sources should be available to any of the connected clients. There should be no need for one-to-one connections.
- Server and client capabilities for both OPC DA and UA - Some systems may offer an OPC DA server interface, and require an OPC UA client to connect to it. Others may have an OPC DA client that needs data from an OPC UA server.
- Maintaining the data model - As the data passes through the system, you don't want to flatten the data hierarchy. A good DA/UA gateway will preserve the data structure from the DA side and reproduce it, as much as possible, in OPC UA.
- Automatic discovery - Let the software discover what data points are in the server and make all of them available to the client to choose from.
