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 │ ╞═══════════════════════════════════════╪══════════════════════════════════════════╡ │nsu=http://opcfoundation.org/UA/ ;i=1 │Boolean │ │nsu=http://opcfoundation.org/UA/ ;i=2 │SByte │ │nsu=http://opcfoundation.org/UA/ ;i=3 │Byte │ │nsu=http://opcfoundation.org/UA/ ;i=4 │Int16 │ │nsu=http://opcfoundation.org/UA/ ;i=5 │UInt16 │ ...
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): ╒══════════════════════════════════════════════╤═════════════════════════════════════════╕ │[] │Value │ ╞══════════════════════════════════════════════╪═════════════════════════════════════════╡ │DataTypes.AccessLevelExType │nsu=http://opcfoundation.org/UA/ ;i=15406│ │DataTypes.AccessLevelType │nsu=http://opcfoundation.org/UA/ ;i=15031│ │DataTypes.AccessRestrictionType │nsu=http://opcfoundation.org/UA/ ;i=95 │ │DataTypes.ActivateSessionRequest │nsu=http://opcfoundation.org/UA/ ;i=465 │ │DataTypes.ActivateSessionResponse │nsu=http://opcfoundation.org/UA/ ;i=468 │ ...
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.
