DI 1.04 defines a CU for the DeviceHealth Variable that says "Supports the DeviceHealth Property" (DeviceHealth is defined as a Component in the IDeviceHealth Facet, not a Property). This CU is included as mandatory in the "DI DeviceHealth Facet" (<a href="https://profiles.opcfoundation.org/profile/2111"> this should show up </a>) defined by UAFX. UAFX created this Facet because DI refused to create a similar one. Maybe this Facet should be named "UAFX DeviceHealth Facet." The DI DeviceHealth Facet is included in the UAFX Asset Facet along with the previously mentioned CU.

Recommendation:
Rename the DI DeviceHealth Facet to "UAFX DeviceHealth Facet" -OR- Remove the DI DeviceHealth Facet altogether and add the DI CUs to the UAFX Asset Facet directly (I prefer the latter since we are not defining the DI stuff and don't need a Facet for it).

There is no CU defined for supporting the DeviceHealthAlarms Folder, unless the DI CU "DI HealthDiagnosticsAlarm" is intended to be that CU. It is described as "Supports DeviceHealth Alarms", which might mean "Supports DeviceHealthAlarms Folder", but I don't know that. It could also mean you support the DeviceHealthDiagnosticAlarmsType, which are the Alarms that should be placed in the DeviceHealth Alarms Folder. We would still need a CU for the Folder if that is the case.

Recommendations:
1) Ask DI to clarify the definition of the DI HealthDiagnosticsAlarm CU to make it clear it means support of the DeviceHealthDiagnosticAlarmsType and its Subtypes (FailureAlarmType, CheckFunctionAlarmType, OffSpecAlarmType, and MaintenanceRequiredAlarmType).
2) Ask DI to add a CU for the support of the DeviceHealth Folder, and then add that CU as optional to the DI DeviceHealth Facet or the UAFX Asset Facet (but not both), depending on how we decide to handle that.

This is a breakdown of what I think need to happen

1) Separate mantis issue on DI CU to change "Supports the DeviceHealth Property" to "Supports the DeviceHealth Variable"
2) I would not change the name and I would include the Facet as is - since we say something an asset when it include the Interface - so no change in that regard - we want the test to be consistent - if you are UAFX or not.
3) I think the CU that is defined is actually about including the folder, - again we could add a Mantis if we think the description of this CU need to be improved - it is part of the interface facet and the two cu are for the two optional items that are in the interface. The Object is called deviceHealthAlarms - so actually it is not that bad - can add the word folder if we want
4) we can also ask for new CU's one for each AlarmType that is defined in DI - I think this could be useful - if we want to make any specific alarm mandatory

Created related Mantis issue to fix Part 100

Updated CU names to the new names in the DI 1.04 Profiles and added the four new CUs for the individual DeviceHealthAlarmType Subtypes in the DI IDeviceHelathFacet.

The AWG decided during the July 2, 2025, meeting to request that the DI WG add the IVendorNameplate Facet, DI ITagNameplate Facet, and DI IDeviceHealth Facet to their Profiles. The Issue was assigned to Paul Hunkar.

Assigned to Paul Hunkar to discuss wih the DI WG.

The DI Facets defined in UAFX have now been defined in DI 1.04 and are referenced from the UAFX Asset Facet.
