# OPC UA Node Properties ## `browseName` (string, required) The browse name (not path) of this node Examples: `"temperature1"`, `"pressure2"` ## `nodeId` (string) The specific node id of this node Example: `"ns=1;s=spindleSpeed"` ## `nodeType` (string, enum, required) The node type: Whether this node is a variable or an object. This element must be one of the following enum values: * `Object` * `Variable` * `Method` ## `historize` (boolean) Whether to accumulate an historian for this node Default: `false` ## `interpolation` (string, enum) The displayed interpolation mode This element must be one of the following enum values: * `stepped` * `sloped` Default: `"sloped"` ## `maxTimeInterval` (integer) Specifies the maximum interval between data points in the history repository regardless of their value change \[in milliseconds] Default: `10000` Example: `1000` ## `minTimeInterval` (integer) Specifies the minimum interval between data points in the history repository regardless of their value change \[in milliseconds] Default: `500` Example: `100` ## `inputArguments` (array) Input arguments for method nodes The object is an array with all elements of the type `object`. The array object has the following properties: #### `name` (string, required) The name of the argument #### `description` (string) Description of the argument #### `dataType` (string, enum, required) The data type of the argument This element must be one of the following enum values: * `Boolean` * `Byte` * `ByteString` * `DataValue` * `DateTime` * `DiagnosticInfo` * `Double` * `ExpandedNodeId` * `ExtensionObject` * `Float` * `Guid` * `Int16` * `Int32` * `Int64` * `LocalizedText` * `NodeId` * `Null` * `QualifiedName` * `SByte` * `StatusCode` * `String` * `UInt16` * `UInt32` * `UInt64` * `Variant` * `XmlElement` #### `valueRank` (integer, enum) The rank of the transported data, default is scalar (-1), use 1 for array of scalars This element must be one of the following enum values: * `-3` * `-2` * `-1` * `0` * `1` * `2` Default: `-1` #### `arrayDimensions` (array) For nodes that represent an array or a multi-dimensional array (e.g. a matrix), this array value specifies the size in each of the dimensions. The object is an array with all elements of the type `number`. Example: `[6,4]` ## `outputArguments` (array) Output arguments for method nodes The object is an array with all elements of the type `object`. The array object has the following properties: #### `name` (string, required) The name of the argument #### `description` (string) Description of the argument #### `dataType` (string, enum, required) The data type of the argument This element must be one of the following enum values: * `Boolean` * `Byte` * `ByteString` * `DataValue` * `DateTime` * `DiagnosticInfo` * `Double` * `ExpandedNodeId` * `ExtensionObject` * `Float` * `Guid` * `Int16` * `Int32` * `Int64` * `LocalizedText` * `NodeId` * `Null` * `QualifiedName` * `SByte` * `StatusCode` * `String` * `UInt16` * `UInt32` * `UInt64` * `Variant` * `XmlElement` #### `valueRank` (integer, enum) The rank of the transported data, default is scalar (-1), use 1 for array of scalars This element must be one of the following enum values: * `-3` * `-2` * `-1` * `0` * `1` * `2` Default: `-1` #### `arrayDimensions` (array) For nodes that represent an array or a multi-dimensional array (e.g. a matrix), this array value specifies the size in each of the dimensions. The object is an array with all elements of the type `number`. Example: `[6,4]` ## `dataType` (string) The data type of this node. This can be either an OPC UA base type (see example values), or a node ID which references a data type node. Examples: `"Boolean"`, `"Byte"`, `"ByteString"`, `"DataValue"`, `"DateTime"`, `"DiagnosticInfo"`, `"Double"`, `"ExpandedNodeId"`, `"ExtensionObject"`, `"Float"`, `"Guid"`, `"Int16"`, `"Int32"`, `"Int64"`, `"LocalizedText"`, `"NodeId"`, `"Null"`, `"QualifiedName"`, `"SByte"`, `"StatusCode"`, `"String"`, `"UInt16"`, `"UInt32"`, `"UInt64"`, `"Variant"`, `"XmlElement"` ## `serializeDataType` (string, enum) For nodes where the data type is not an OPC UA base type but a node reference, the data type for serialization of values sometimes needs to be specified separately here. This must be a basic OPC UA data type. This element must be one of the following enum values: * `Boolean` * `Byte` * `ByteString` * `DataValue` * `DateTime` * `DiagnosticInfo` * `Double` * `ExpandedNodeId` * `ExtensionObject` * `Float` * `Guid` * `Int16` * `Int32` * `Int64` * `LocalizedText` * `NodeId` * `Null` * `QualifiedName` * `SByte` * `StatusCode` * `String` * `UInt16` * `UInt32` * `UInt64` * `Variant` * `XmlElement` ## `valueRank` (integer, enum) The rank of the transported data, default is scalar (-1), use 1 for array of scalars This element must be one of the following enum values: * `-3` * `-2` * `-1` * `0` * `1` * `2` Default: `-1` ## `arrayDimensions` (array) For nodes that represent an array or a multi-dimensional array (e.g. a matrix), this array value specifies the size in each of the dimensions. The object is an array with all elements of the type `number`.

Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.cybus.io/2-1-2/connectors/servers/opc-ua-server/opcuanode.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
