16.2.2 Index
The Index Property gives the number of the power unit.
16.2.3 IsPresent
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.
16.2.4 Id
The Id Property represents the Id of the PowerUnit.
16.2.5 PowerOn
The PowerOn Property indicates if the PowerUnit is switched on.
16.2.6 ActualTemperature
The ActualTemperature Variable represents the current temperature of the PowerUnit.
