This data model is based on the following specifications:
Additionally, the following literature is respected:
The asset is actively producing.
The asset is running on full speed.
The asset is NOT running on full speed.
NOT INCLUDED FOR NOW:
The asset is in an unspecified state.
We do not have any data for that asset (e.g. connection to PLC aborted).
The asset is not producing, but we do not know why (yet).
The asset is not producing for a short period (typically around 5 minutes), but we do not know why (yet).
The asset has issues with materials.
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.
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.
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.
The asset has a material issue, but it is not further specified.
The asset is in a stop which is belongs to the process and cannot be avoided.
The asset is in a changeover process between products.
The asset is currently in a cleaning process.
The asset is currently emptied, e.g. to prevent mold for food products over the long breaks like the weekend.
The machine is currently preparing itself for production, e.g. heating up.
The asset is stopped because of the operator.
The operator is not at the machine.
The operator is in a break. note: different than planned shift as it could count to performance losses
The asset is stopped as it is planned to stop (planned idle time).
There is no shift planned at that asset.
There is no order planned at that asset.
The asset has a technical issue.
The asset itself is defect, e.g. a broken engine.
There is a external failure, e.g. missing compressed air
There is an external interference, e.g. the crane to move the material is currently unavailable.
A planned maintenance action.
The asset has a technical issue, but it is not specified further.
