The OperationalType provides Variables useful during normal operation, such as Quantities and states, and is formally defined in Table 95.

The optional Variable HealthState is used for Airnets and Components and describes whether the Main Function of a Component or the Requirements of an Airnet can be fulfilled. The states may be influenced by the events and condition instances in an Events FunctionalGroup. The concrete connection between an event or condition and the Variable HealthState is system and manufacturer specific and is not specified by this specification. Some subtypes of this OperationalType define more specific states and provide a more specific definition of this Variable.

The optional Variable IntegratedState is used for Airnets and Components and describes the degree of control over compressed air generation and/or treatment. Some subtypes of this OperationalType define more specific states and provide a more specific definition of this Variable.

The optional Variable OnOff describes whether a Component is switched on or switched off. Some subtypes of this OperationalType define more specific states and provide a more specific definition of this Variable.

The optional Variable OperatingState is used for Airnets and Components and describes whether the Main Function of a Component or the Requirements of an Airnet should be fulfilled. Some subtypes of this OperationalType define more specific states and provide a more specific definition of this Variable.

When instantiating this OperationalType, the abstract DataType 0:Enumeration for HealthState, IntegratedState, and OperatingState shall be changed to a CASPart specific concrete DataType or one of the general DataTypes HealthStateEnum, IntegratedStateEnum, OperatingStateEnum.

The InstanceDeclarations of the OperationalType have additional Attributes defined in Table 96.

Table 96 – OperationalType Attribute values for child Nodes

Source Path Value Attribute Description Attribute
HealthState   Actual health state of the part.
IntegratedState   Actual integrated state of the part.
OnOff   Actual OnOff state of the component.

   OnOff
   0:FalseState
   
“The component is switched off and not able to operate.”  

   OnOff
   0:TrueState
   
“The component is switched on and is in a specific operating state.”  
OperatingState   Actual operating state of the part.
