Members

The CIM_ControlledBy class has these types of members:

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.

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.
