CygNet OPC UA Server NodeId Formats
This topic describes the formats of the various NodeIds that are part of the CygNet address space in the OPC UA server.
The structure of the OPC UA NodeId is described in OPC 10000-3: OPC UA Specification Part 3: Address Space Model, Section 8.2.1.
The NodeId is a standard built-in DataType composed of three elements that identify a Node within a Server. It is defined as having the following three elements:
- namespaceIndex — nodes in the CygNet OPC UA Server's address space have a namespaceIndex of 2
- identifierType — nodes in the CygNet OPC UA Server's address space have an identifierType value of STRING_1 (String value)
- identifier — the Identifier element's format varies according to the type of node in the address space as defined in the table below:
Identifier by DataType
