CIM_DeviceConnection class

The CIM_DeviceConnection association class represents two or more connected devices.

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.

Syntax

class CIM_DeviceConnection : CIM_Dependency
{
  CIM_LogicalDevice REF Antecedent;
  CIM_LogicalDevice REF Dependent;
  uint32            NegotiatedDataWidth;
  uint64            NegotiatedSpeed;
};

Members

The CIM_DeviceConnection class has these types of members:

Properties

The CIM_DeviceConnection class has these properties.

Antecedent
Data type: CIM_LogicalDevice
Access type: Read-only

Reference to a logical device. This property is inherited from CIM_Dependency.

Dependent
Data type: CIM_LogicalDevice
Access type: Read-only

Reference to a second logical device that is connected to the Antecedent device. This property is inherited from CIM_Dependency.

NegotiatedDataWidth
Data type: uint32
Access type: Read-only

When several bus or connection-data widths are possible, this property defines the one 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 important to device management, the property should be set to 0 (zero).

NegotiatedSpeed
Data type: uint64
Access type: Read-only

When several bus or connection speeds are possible, this property defines the one being used between the devices. Speed is specified in bits-per-second. If connection or bus speeds are not negotiated, or if this information is not available or important to device management, the property should be set to 0 (zero).

For more information about using uint64 values in scripts, see Scripting in WMI.

Remarks

The CIM_DeviceConnection class is derived from CIM_Dependency.

WMI does not implement this class. For more information about classes derived from CIM_DeviceConnection, 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.
