Devices - 10.2 Device Server Facets

The following tables specify the Facets available for Servers that implement the Devices companion standard. Table 66 describes Conformance Units included in the minimum needed Facet. It includes the organisation of instantiated Devices in the Server AddressSpace.

Table 66 – BaseDevice_Server_Facet definition

Conformance Unit	Description	Optional/ Mandatory
DI Information Model	Supports Objects that conform to the types specified in the chapter Device model of this companion standard. This includes in particular Objects of (subtypes of) ComponentType and FunctionalGroups.	M
DI DeviceSet	Supports the DeviceSet object to aggregate Device instances.	M
DI Nameplate	Supports Properties of the VendorNameplate Interface defined in 5.5.2.	O
DI Software Component	Supports Objects of SoftwareType or a subtype.	O
DI DeviceHealth	Supports the DeviceHealth Property defined in 5.5.3.	O
DI DeviceSupportInfo	Server provides additional data for its Devices as defined in 5.5.5.	O

Table 67 defines a Facet for the identification FunctionalGroup of Devices. This includes the option of identifying the Protocol(s).

Table 67 – DeviceIdentification_Server_Facet definition

Conformance Unit	Description	Optional/ Mandatory
DI Identification	Supports the Identification FunctionalGroup for Devices.	M
DI Protocol	Supports the ProtocolType and instances of it to identify the used communication profiles for specific instances.	O

Table 68 defines extensions specifically needed for BlockDevices.

Table 68 – BlockDevice_Server_Facet definition

Conformance Unit	Description	Optional/ Mandatory
DI Blocks	Supports the BlockType (or subtypes respectively) and the Blocks Object in some of the instantiated Devices.	M

Table 69 defines a Facet for the Locking AddIn Capability. This includes the option of breaking a lock.

Table 69 – Locking_Server_Facet definition

Conformance Unit	Description	Optional/ Mandatory
DI Locking	Supports the LockingService for certain TopologyElements.	M
