9.2 Profiles

9.2.1 Overview

The structure of the Companion Specification Profile and its Facets is interdependent, as depicted in Figure 20. Implementations of the Companion Specification are required to fulfil the LADS BaseServer Server Profile. Additionally, up to three optional Facets - Maintenance, ProgramManager, and ExtendedFunctionalUnit (blue) - can be implemented.

The Maintenance Facet encompasses all necessary nodes for maintenance use cases. The ProgramManager Facet includes all nodes for read-only Program Management, which can be expanded with management methods in the ExtendedProgramManager.

The ExtendedFunctionalUnit Profile mandates the optional methods of the FunctionalUnit, enabling control of a functional unit and a program. This structure provides a comprehensive and flexible framework for implementing the LADS Companion Specification.

In addition, at least one Facet function (grey) needs to be implemented. For the CoverFunction and the ControllerFunction, there is a base Profile (read-only) and an extended Profile with method and write implementation.

Table 134 lists all Profiles defined in this document and defines their URIs.

9.2.3 Server Facets

9.2.3.1 Overview

The following sections specify the Facets available for Servers that implement the LADS companion specification. Each section defines and describes a Facet or Profile.

9.2.3.2 LADS BaseServer Server Profile

Table 135 defines a Profile that describes a basic LADS OPC UA Server.

9.2.3.3 LADS Maintenance Server Facet

Table 136 defines a Profile that contains all necessary conformance units for maintenance tasks.

9.2.3.4 LADS ProgramManager Server Facet

Table 137 defines a Profile that contains all necessary conformance units for program monitoring.

9.2.3.5 LADS ExtendedProgramManager Server Facet

Table 138 defines a Profile that contains all necessary conformance units for complete program management, including up- and download of program templates.

9.2.3.6 LADS ExtendedFunctionalUnit Server Facet

Table 139 defines a Profile that contains all conformance units which extend a Functional Unit with Methods.

9.2.3.7 LADS CoverFunction Server Facet

Table 140 defines a Profile which contains all conformance units for implementing a cover function.

9.2.3.8 LADS ExtendedCoverFunction Server Facet

Table 141 defines a Profile which contains all conformance units for implementing a cover function and extending the CoverFunction with Methods.

9.2.3.9 LADS SensorFunction Server Facet

Table 142 defines a Profile that a Server can provide if a Sensor is used in the model. At least one of the optional conformance units must also be implemented.

9.2.3.10 LADS ControllerFunction Server Facet

Table 143 defines a Profile that a Server can provide if a Controller system is used in the model. At least one of the optional conformance units must also be implemented.

9.2.3.11 LADS ExtendedControllerFunction Server Facet

Table 144 defines a Profile which extends the ControllerFunction Server Facet with method calls.
