CIM_ControlledBy class
Represents a relationship between a controller and a logical device that is managed by the controller.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Properties
The CIM_ControlledBy class has these properties.
-
AccessMode
-
-
Data type: uint16
-
Access type: Read-only
This property that describes the accessibility of the device through the controller.
-
-
ReadWrite (2)
-
ReadOnly (3)
-
NoAccess (4)
AccessPriority
-
Data type: uint16
-
Access type: Read-only
The priority for access of the device through the controller. A lower value indicates a higher priority.
AccessState
-
Data type: uint16
-
Access type: Read-only
Indicates whether the controller is actively managing the device.
Unknown (0)
Active (1)
Inactive (2)
Antecedent
-
Data type: CIM_Controller
-
Access type: Read-only
-
Qualifiers: Override ("Antecedent")
The controller.
Dependent
-
Data type: CIM_LogicalDevice
-
Access type: Read-only
-
Qualifiers: Override ("Dependent")
The logical devices.
DeviceNumber
-
Data type: string
-
Access type: Read-only
The address of the associated device in the context of the controller.
NegotiatedDataWidth
-
Data type: uint32
-
Access type: Read-only
-
Qualifiers: Units ("Bits"), MappingStrings ("MIF.DMTF|Bus Port Association|001.3"), PUnit ("bit")
When several bus and connection data widths are possible, the NegotiatedDataWidth property defines the one that is in use between the Devices. Data width is specified in bits. If data width is not negotiated, or if this information is not available or not important to Device management, the property should be set to 0.
This property is inherited from CIM_DeviceConnection.
NegotiatedSpeed
-
Data type: uint64
-
Access type: Read-only
-
Qualifiers: Units ("Bits per Second"), MappingStrings ("MIF.DMTF|Bus Port Association|001.2"), PUnit ("bit / second")
When several bus and connection speeds are possible, this property defines the speed that is in use between the devices, in bits per second. If connection or bus speeds are not negotiated, or if this information is not available, or not important to device management, the property should be set to "0".
This property is inherited from CIM_DeviceConnection.
NumberOfHardResets
-
Data type: uint32
-
Access type: Read-only
-
Qualifiers: Counter
The number of hard resets issued by the controller. A hard reset returns a device to its initialization or boot-up state, after which all internal device state information and data are lost.
NumberOfSoftResets
-
Data type: uint32
-
Access type: Read-only
-
Qualifiers: Counter
The number of soft resets issued by the controller. A soft reset does not clear the device state or data.
TimeOfDeviceReset
-
Data type: datetime
-
Access type: Read-only
The time when the downstream device was last reset by the controller.
