• -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)

The object is an array with all elements of the type object.

The array object has the following properties:

name (string, required)

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

• Null

• QualifiedName

• SByte

• StatusCode

• String

• UInt16

• UInt32

• UInt64

• Variant

• XmlElement

valueRank (integer, enum)
