Command, Arguments and Options

Command: ua nodeId

Example: Figure out standard name of a node ID in namespace 0 (reserved by OPC Foundation):

ua nodeId i=2253

Output:

Standard name: Server
Expanded text: nsu=http://opcfoundation.org/UA/ ;i=2253

Example: Find out a full node ID from its standard name (for nodes defined by OPC Foundation):

ua ni -sn=Server_NamespaceArray

Output:

Standard name: Server_NamespaceArray
Expanded text: nsu=http://opcfoundation.org/UA/ ;i=2255

Example: Display a table of all node IDs defined by OPC Foundation, sorted by their identifier.

ua nodeId listNames?

Output:

Result (sequence):
╒═══════════════════════════════════════╤══════════════════════════════════════════╕
│[]                                     │Value                                     │

...

The output sequence is truncated by default; in order to obtain the full table, use:

ua nodeId listNames? -!vs=:N99999

Example: Display a table of all node IDs defined by OPC Foundation, sorted by their class and standard name (alphabetically):

ua nodeId listValues?

Output:

Result (sequence):
╒══════════════════════════════════════════════╤═════════════════════════════════════════╕

The output sequence is truncated by default; in order to obtain the full table, use:

ua nodeId listValues? -!vs=:N99999

Command: ua qualifiedName

Similarly to the nodeId command, you can use this command e.g. to obtain tables of qualified names defined by the OPC Foundation.

Example:

ua qn ln?

which is an abbreviated form of:

ua qualifiedName listNames?

Command: ua statusCode

The statusCode command decodes and encodes OPC UA status codes.
