Asset States

Asset States are defined as master data and include a set of predefined states that can be used based on the requirement.

Each asset has a current state that indicates the usability and operational status. The Asset State changes are tracked throughout the life cycle of an asset to provide full traceability. This functionality supports real-time decision making and maintenance prioritization.

Assets can be configured with default states for each of these situations:

  • In Use
  • Requires Repair
  • Requires Inspection
  • Not in Use
  • Requires Cleaning
  • Clean State
  • End of Life
  • In Tool Assembly

Each asset state includes a set of flags that determine which activities can be performed for an asset when in the defined asset state. These flags must be configured correctly to ensure the appropriate activities are permitted.

Some flags are mutually exclusive, while others can be enabled concurrently.

The available Asset State flags include:

  • Available For Use: Indicates that the asset is in a good state and can be used as required.
  • Asset In Use: Indicates that the asset is currently being used, for example a tool is loaded into a machine.
  • Requires Cleaning: Indicates that the asset has been used and must be cleaned before reuse.
  • Requires Maintenance: Indicates that asset requires maintenance work. This requirement can be identified manually, or automatically.
  • Requires Measuring: Indicates that asset must be measured before use to validate the asset is within tolerance. This is applicable to assets whose properties or settings may change because of normal use.
  • Requires Repairing: Indicates that the asset has been identified as damaged and must be repaired before further use. This condition can be identified manually or automatically.
  • In Tool Assembly: For a tool asset (assets that are represented as tools) that can be assembled into a pack as a sub-tool, this state represents that a tool is currently assembled into a toolpack.
  • End of Life: Indicates that the asset has reached the end of the life and must no longer be used.

In addition to manual state changes, automated state transitions can occur for assets, in the these situations:

  • Available For Use: The asset is available to be used in these scenarios:
    • When an inspection is completed without specification violations.
    • When maintenance is completed and no additional maintenance is required.
    • When the asset has been cleaned.
    • When the asset is disassembled from a toolpack.
  • Asset In Use: When a tool asset is loaded into a machine.
  • Requires Inspection: When inspection is required for the asset.
  • End of life: When the quantity produced by the asset exceeds the defined end-of-life threshold.
  • Requires Maintenance: When outstanding maintenance work exists for the asset.
  • In Tool Assembly: When a sub-tool is assembled into a toolpack.
