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.
