When instances for power units are created, the BrowseNames shall be “PowerUnit_<Nr>” (starting with 1).
This ObjectType represents information on the hydraulic units and electric drives. It is formally defined in Table 62.

The Index Property gives the number of the power unit.
This Property informs the client if the power unit is physically present and connected. May be FALSE e.g. when instances for possible power units are created (depending on the capabilities/connectors of the machine) which are currently not used.
The Id Property represents the Id of the PowerUnit.
The PowerOn Property indicates if the PowerUnit is switched on.
The ActualTemperature Variable represents the current temperature of the PowerUnit.
There are two subtypes: HydraulicUnitType and ElectricDriveType.
