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)

• 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.

Example: [6,4]
