Health Categories


Users want health indications of assets managed by an OPC UA Server to be categorized by importance.


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.
