Users want assets managed by an OPC UA Sever to have classified health indications. Proposed indications:

Critical Fault – Something has permanently failed.

Major Recoverable Fault – An asset can no longer perform its function. Intervention is required.

Minor Recoverable Fault – An asset has experienced a problem but is able to continue operation until intervention occurs.

Maintenance Needed – Service is required to keep the asset operating within its designed tolerances.

Limited Resource Capacity Near Limit – A limited resource met a threshold beyond which a more serious fault would occur.

Ideally users may want the ability to reassign indications to other categories based on their application.
