OPC Foundation UA .NET Standard Reference Server
Introduction
The console reference server can be configured using several console parameters. Some of these parameters are explained in more detail below.
To see all available parameters call console reference server with the parameter -h.
Reverse Connect
The OPC UA reverse connect feature allows an OPC UA server to initiate the connection to a client, rather than the traditional model where clients connect to servers. This is particularly useful in scenarios where the server is behind a firewall or NAT, making it difficult for clients to directly connect to it.
How to use Reverse Connect
To enable reverse connect mode, specify the client endpoint URL using the --rc or --reverseconnect parameter:
dotnet ConsoleReferenceServer.dll --rc=opc.tcp://localhost:65300
or
dotnet ConsoleReferenceServer.dll --reverseconnect=opc.tcp://localhost:65300
Example: Server and Client with Reverse Connect
-
Start the client with reverse connect listener on port 65300:
dotnet ConsoleReferenceClient.dll --rc=opc.tcp://localhost:65300 opc.tcp://localhost:62541/Quickstarts/ReferenceServer -
In a separate terminal, start the server with reverse connect to the client:
dotnet ConsoleReferenceServer.dll --rc=opc.tcp://localhost:65300 -a
The server will establish a reverse connection to the client endpoint, and the client will use this connection to communicate with the server.
Additional Options
-aor--autoaccept: Auto accept untrusted certificates (for testing only)-cor--console: Log to console-lor--log: Log app output-tor--timeout: Timeout in seconds to exit application
For the complete list of options, use --help.
