CIM_LogicalDevice class

The CIM_LogicalDevice class represents a hardware entity that may or may not be realized in physical hardware.

Important  The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.

The following syntax is simplified from Managed Object Format (MOF) code and includes all inherited properties. Properties are listed in alphabetic order, not MOF order.

ConfigManagerUserConfig
Data type: boolean
Access type: Read-only

If TRUE, the device is using a user-defined configuration.

CreationClassName
Data type: string
Access type: Read-only

Name of the class or subclass used in the creation of an instance. When used with other key properties of the class, this property allows all instances of the class and its subclasses to be uniquely identified.

Description

Access type: Read-only

Free-form string that supplies information about the error recorded in the LastErrorCode property and corrective actions to perform.

InstallDate

Remarks

Logical device characteristics that manage operation or configuration are contained in, or associated with, the CIM_LogicalDevice object. Printer operational properties, for example, are supported paper sizes or detected errors. Sensor device configuration properties, for example, are threshold settings. Various configurations can exist for a logical device and are contained in the CIM_Setting objects, which are associated with the logical device.

The CIM_LogicalDevice class is derived from CIM_LogicalElement.

WMI does not implement this class. For classes derived from CIM_LogicalDevice, see Win32 Classes.

This documentation is derived from the CIM class descriptions published by the DMTF. Microsoft may have made changes to correct minor errors, conform to Microsoft SDK documentation standards, or provide more information.
