The component Variables of the CleaningUnitType have additional Attributes defined in Table 75.

Table 75 – CleaningUnitType Attribute values for child nodes
BrowsePath Description Attribute
<Valve>The valves that are part of the cleaning unit.
2:IdentificationData for machine identification (OPC 40001-1).
CleaningActiveDescribes that the unit is currently in a cleaning cycle.
ReservoirPressureDescribes the pressure of the compressed gas reservoir of the system.
TotalCleaningCyclesCount of the number of cleaning cycles carried out by the cleaning system.
FilterCleaningEffectThe filter cleaning effect describes the change in state of the separator after the last cleaning cycle has been run through. This can be, for example, a change in the pressure difference before and after the cleaning cycle.
CleaningRecommendedIndicates that cleaning of the separator is recommended.
4:MachineryItemStateStateMachine representing the operating state of the unit (OPC 40001-1).
MalfunctionIndicates that the cleaning unit is malfunctioning. True in case of error. Malfunctions can be, for example, that the filter cleaning effect is not sufficient.
AutomaticCleaningEnabledIf enabled, the cleaning unit may automatically perform the cleaning according to predefined rules when cleaning is necessary. Otherwise, automatic cleaning is blocked.
CleaningIntervalTime between cleaning cycles.
AirConsumptionDescribes the current consumption of compressed air.
