IEC 62541-5 Ed. 4.0 b:2026

Full Description

This part of IEC 62541 defines the Information Model. The Information model describes standardised Nodes of a Server’s AddressSpace. These Nodes are standardised types as well as standardised instances used for diagnostics or as entry points to server-specific Nodes. Thus, the Information Model defines the AddressSpace of an empty OPC UA Server. However, it is not expected that all Servers will provide all of these Nodes.
Annex C defines the OPC Binary Types Description System.
Annex B refers to encoding information for custom DataTypes in previous versions of this document.
