6 LADS Information Model Overview

This Companion Specification is based on OPC 10000-100 (Devices), OPC 10000-110 (Asset Management Basics) and OPC 40001-1 (OPC UA for Machinery). These Companion Specifications create an entry point for Devices or machines in the AddressSpace. Instances of a LADSDeviceType shall either directly or indirectly referenced with a Hierarchical Reference to the DeviceSet and can be referenced from Machines with an Organizes Reference.

A LADSDeviceType may have both References (to DeviceSet and Machines), depending on the environment of the Device. Both References are needed if the LADSDeviceType is used in a production environment or in a laboratory close to production.

Figure 10 shows an example representation of a LADSDeviceType instance in the AddressSpace.
