Understand raw reason codes

  • Last UpdatedApr 24, 2026

Machine utilization raw reason codes can be sent directly from an entity to MES (for example, via a UCO). Depending on how the raw reason code is configured in the UCO or in MES Client, it will create a new utilization event in the MES database, using the utilization reason to which the raw reason code was mapped.

If a raw reason code that is not configured for the entity is received, the Unknown Reason utilization reason, which is configurable in MES Web Portal, is used.
