Win32_PnPEntity class

The Win32_PnPEntity WMI class represents the properties of a Plug and Play device. Plug and Play entities are shown as entries in the Device Manager located in Control Panel.

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

Caption
Data type: string
Access type: Read-only

Short description of the object. This property is inherited from CIM_ManagedSystemElement.

ClassGuid
Data type: string
Access type: Read-only

Globally unique identifier (GUID) of this Plug and Play device.

CompatibleID
Data type: string array
Access type: Read-only

A vendor-defined identification string that Setup uses to match a device to an INF file. A device can have a list of compatible IDs associated with it. The compatible IDs should be listed in order of decreasing suitability. If Setup cannot locate an INF file that matches one of a device's hardware IDs, it uses compatible IDs to locate an INF file. A compatible ID has the same format as a HardwareID. For more information, see Windows Driver Kit.

Windows Server 2003:  This property is not available.

ConfigManagerErrorCode
Data type: uint32
Access type: Read-only

Win32 Configuration Manager error code.

ConfigManagerUserConfig
Data type: boolean
Access type: Read-only

If TRUE, the device is using a user-defined configuration. This property is inherited from CIM_LogicalDevice.

CreationClassName
Data type: string
Access type: Read-only

Name of the first concrete class to appear in the inheritance chain used in the creation of an instance. When used with the other key properties of the class, the property allows all instances of this class and its subclasses to be uniquely identified. This property is inherited from CIM_LogicalDevice.

Description
Data type: string
Access type: Read-only

Description of the object. This property is inherited from CIM_ManagedSystemElement.

DeviceID
Data type: string
Access type: Read-only
Qualifiers: Key

Identifier of the Plug and Play device. This property is inherited from CIM_LogicalDevice.

ErrorCleared
Data type: boolean
Access type: Read-only

If TRUE, the error reported in LastErrorCode is now cleared. This property is inherited from CIM_LogicalDevice.

ErrorDescription
Data type: string
Access type: Read-only

More information about the error recorded in LastErrorCode, and information about any corrective actions that may be taken. This property is inherited from CIM_LogicalDevice.

HardwareID
Data type: string array
Access type: Read-only

A vendor-defined identification string that Setup uses to match a device to an INF file. Normally, a device has an associated list of hardware IDs. An exception is the 1394 bus driver, which does not use hardware IDs. The first hardware ID in the list should be the device ID. The remaining IDs should be listed in order of decreasing suitability.

Hardware IDs appear in one the following formats:

  • enumerator\enumerator-specific-device-ID

    This is the most common format for individual PnP devices. An example of an enumerator is the BIOS or ISAPNP.

  • *enumerator-specific ID

    An asterisk (*) indicates use by more than one enumerator.

  • device-class-specific ID

    A custom format.

Examples of Hardware IDs are:

root\*PNPOF08
PC\VEN_1000&DEV_001&SUBSYS_00000000&REV_02

For more information, see the Windows Driver Kit.

Windows Server 2003:  This property is not available.

InstallDate
Data type: datetime
Access type: Read-only

Date and time the object was installed. This property does not need a value to indicate that the object is installed. This property is inherited from CIM_ManagedSystemElement.

LastErrorCode
Data type: uint32
Access type: Read-only

Last error code reported by the logical device. This property is inherited from CIM_LogicalDevice.

Manufacturer
Data type: string
Access type: Read-only

Name of the manufacturer of the Plug and Play device.

Example: "Acme"

Name
Data type: string
Access type: Read-only

Label by which the object is known. When subclassed, the property can be overridden to be a key property. This property is inherited from CIM_ManagedSystemElement.

PNPDeviceID
Data type: string
Access type: Read-only

Windows Plug and Play device identifier of the logical device. This property is inherited from CIM_LogicalDevice.

Example: "*PNP030b"

PowerManagementCapabilities
Data type: uint16 array
Access type: Read-only

Not implemented.

PowerManagementSupported
Data type: boolean
Access type: Read-only

Not implemented.

Service
Data type: string
Access type: Read-only

Name of the service that supports this Plug and Play device. For more information, see Win32_SystemDriverPnPEntity.

Example: "atapi"

Status
Data type: string
Access type: Read-only
Qualifiers: MaxLen (10)

Current status of the object. Various operational and nonoperational statuses can be defined. Operational statuses include: "OK", "Degraded", and "Pred Fail" (an element, such as a SMART-enabled hard disk drive, may be functioning properly but predicting a failure in the near future). Nonoperational statuses include: "Error", "Starting", "Stopping", and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is online, yet the managed element is neither "OK" nor in one of the other states. This property is inherited from CIM_ManagedSystemElement.

The values are:

"OK"
"Error"
"Degraded"
"Unknown"
"Pred Fail"
"Starting"
"Stopping"
"Service"
"Stressed"
"NonRecover"
"No Contact"
"Lost Comm"

ValueMeaning
1

Other

2

Unknown

3

Enabled

4

SystemCreationClassName
Data type: string
Access type: Read-only

SystemName
Data type: string
Access type: Read-only

Name of the scoping system. This property is inherited from CIM_LogicalDevice.

Remarks

The Win32_PnPEntity class is derived from CIM_LogicalDevice.

Examples

The Get-BrokenHardware.ps1 PowerShell sample on TechNet Gallery uses to Win32_PnPEntity to retrieve a list of non-working hardware using WMI.

The following VBScript code example connects to a group of remote computers in the same domain by creating an array of remote computer names and then displaying names of the Plug and Play devices—instances of Win32_PnPEntity—on each computer.


On Error Resume Next 
arrComputers = Array("Computer1","Computer2","Computer3")
For Each strComputer In arrComputers
    WScript.Echo
    WScript.Echo "===================================="
    WScript.Echo "Computer: "& strComputer
    WScript.Echo "===================================="

    Set objWMIService = GetObject("winmgmts:\\" _
        & strComputer& "\root\CIMV2") 
    Set colItems = objWMIService.ExecQuery( _
        "SELECT * FROM Win32_PnPEntity",,48) 
    For Each objItem in colItems 
        Wscript.Echo "-----------------------------------"
        Wscript.Echo "Win32_PnPEntity instance"
        Wscript.Echo "-----------------------------------"
        Wscript.Echo "Name: "& objItem.Name
        Wscript.Echo "Status: "& objItem.Status
    Next
