Commands, Arguments and Options
Command: uaServer
This command creates an OPC UA server with pre-defined content (data variables with various behavior and data types under the standard Objects folder). By default, it will open its endpoint (when started) on "opc.tcp://localhost:48040/".
If you simply enter the uaServer command (optionally with some arguments, but no sub-commands), the OpcCmd enters an interactive mode for this command, and you can continue by issuing one or more sub-commands, each on a separate line. Alternatively, you can include some sub-command directly following the uaServer command (with its optional arguments), in which case the sub-command will be performed immediately.
CAUTION: Each uaServer command invocation works on a separate, new server component. If you want to perform multiple operations with the same server, issue the uaServer command (and its arguments) just once, entering its interactive mode (manifested by the uaServer> prompt on the console). Then, issue the sub-commands (such as start), leaving out the uaServer command prefix.
Command: uaServer start
This command starts the OPC UA server.
While the start command is executing, events related to the edge node operations are displayed on the console.
Sub-commands
By default, the server runs until the you press X on the keyboard. Use the !wait sub-command to specify a finite duration.
Command: uaServer addMesh
This command adds nodes to the OPC UA server address space mesh. You need to specify the mesh name, and optionally a mesh-specific parameter. Currently, only one mesh is available, named PerformanceNodes. The optional parameter is an integer specifying the count of shared counter nodes (defaults to 10000).
The mesh(es) need to be added before you start the server.
Example:
uaServer
addMesh PerformanceNodes 20000
start
