UNKNOWN (30000-59999)

The asset is in an unspecified state.

30000: UnknownState

We do not have any data for that asset (e.g. connection to PLC aborted).

Examples for UnknownState

  • WS_Cur_Prog: Undefined
  • EUROMAP: Offline

40000: UnspecifiedStopState

The asset is not producing, but we do not know why (yet).

  • WS_Cur_State: Clearing
  • PackML/Tobacco: Clearing
  • WS_Cur_State: Emergency Stop
  • WS_Cur_State: Resetting
  • PackML/Tobacco: Clearing
  • WS_Cur_State: Held

  • PackML/Tobacco: Idle
  • PackML/Tobacco: Complete
  • EUROMAP: READY_TO_RUN

50000: MicrostopState

The asset is not producing for a short period (typically around 5 minutes), but we do not know why (yet).

MATERIAL (60000-99999)

The asset has issues with materials.

60000: InletJamState

The machine does not perform its intended function due to a lack of material flow in the infeed of the machine detected by the sensor system of the control system (machine stop). In the case of machines that have several inlets, the condition of lack in the inlet refers to the main flow, i.e. to the material (crate, bottle) that is fed in the direction of the filling machine (central machine). The defect in the infeed is an extraneous defect, but because of its importance for visualization and technical reporting, it is recorded separately.

Examples for InletJamState

  • WS_Cur_State: Lack

70000: OutletJamState

The machine does not perform its intended function as a result of a jam in the good flow discharge of the machine detected by the sensor system of the control system (machine stop). In the case of machines that have several discharges, the jam in the discharge condition refers to the main flow, i.e. to the good (crate, bottle) that is fed in the direction of the filling machine (central machine) or is fed away from the filling machine. The jam in the outfeed is an external fault 1v, but it is recorded separately “because” of its importance for visualization and technical reporting.

Examples for OutletJamState

  • WS_Cur_State: Tailback

80000: CongestionBypassState

The machine does not perform its intended function due to a shortage in the bypass supply or a jam in the bypass discharge of the machine detected by the sensor system of the control system (machine stop). This condition can only occur in machines that have two outlets or inlets and in which the bypass is in turn the inlet or outlet of an upstream or downstream machine of the filling line (packaging and palletizing machines). The jam/shortage in the auxiliary flow is an external fault, but is recorded separately due to its importance for visualization and technical reporting.

Examples for CongestionBypassState

  • WS_Cur_State: Lack/Tailback Branch Line

90000: MaterialIssueOtherState

The asset has a material issue, but it is not further specified.

Examples for MaterialIssueOtherState

  • WS_Mat_Ready (Information about which material is lacking)
  • PackML/Tobacco: Suspended

PROCESS (100000-139999)

The asset is in a stop which is belongs to the process and cannot be avoided.

100000: ChangeoverState

The asset is in a changeover process between products.

Examples for ChangeoverState

  • WS_Cur_Prog: Program-Changeover
  • Tobacco: CHANGE OVER

110000: CleaningState

The asset is currently in a cleaning process.

Examples for CleaningState

  • WS_Cur_Prog: Program-Cleaning
  • Tobacco: CLEAN

120000: EmptyingState

The asset is currently emptied, e.g. to prevent mold for food products over the long breaks like the weekend.

Examples for EmptyingState

  • Tobacco: EMPTY OUT

130000: SettingUpState

The machine is currently preparing itself for production, e.g. heating up.

Examples for SettingUpState

  • EUROMAP: PREPARING

OPERATOR (140000-159999)

The asset is stopped because of the operator.

140000: OperatorNotAtMachineState

The operator is not at the machine.

150000: OperatorBreakState

The operator is in a break. note: different than planned shift as it could count to performance losses

Examples for OperatorBreakState

  • WS_Cur_Prog: Program-Break

PLANNING (150000-179999)

The asset is stopped as it is planned to stop (planned idle time).

160000: NoShiftState

There is no shift planned at that asset.

170000: NoOrderState

There is no order planned at that asset.

TECHNICAL (180000-229999)

The asset has a technical issue.

180000: EquipmentFailureState

The asset itself is defect, e.g. a broken engine.

Examples for EquipmentFailureState

  • WS_Cur_State: Equipment Failure

190000: ExternalFailureState

There is a external failure, e.g. missing compressed air

Examples for ExternalFailureState

  • WS_Cur_State: External Failure

200000: ExternalInterferenceState

There is an external interference, e.g. the crane to move the material is currently unavailable.

210000: PreventiveMaintenanceStop

A planned maintenance action.

Examples for PreventiveMaintenanceStop

  • WS_Cur_Prog: Program-Maintenance
  • PackML: Maintenance
  • EUROMAP: MAINTENANCE
  • Tobacco: MAINTENANCE
