Description

The Win32_1394ControllerDevice class represents an association between the high-speed serial bus (IEEE 1394 Firewire) Controller and the CIM_LogicalDevice connected to it. This serial bus provides enhanced connectivity for a wide range of devices, including consumer audio/video components, storage peripherals, other computers, and portable devices. IEEE 1394 has been adopted by the consumer electronics industry and provides a Plug and Play-compatible expansion interface.

Detailed description of Win32_1394ControllerDevice properties

Derived properties (7) of Win32_1394ControllerDevice class

AccessState property
CIMTYPE'uint16'
Description'The AccessState property indicates whether the controller is actively commanding or accessing the device (value=1) or not (value=2). Also, the value, "Unknown" (0), can be defined. This information is necessary when a logical device can be commanded by, or accessed through, multiple controllers.'
readTrue
Values['Unknown', 'Active', 'Inactive']
AccessState property is in 11 classes of ROOT\cimv2 and in 4 namespaces
Antecedent property
CIMTYPE'ref:Win32_1394Controller'
Description'The Win32_1394Controller antecedent reference represents the 1394 controller associated with this device.'
keyTrue
MappingStrings['WMI|Win32_1394Controller']
Override'Antecedent'
readTrue
Antecedent property is in 103 classes of ROOT\cimv2 and in 15 namespaces
Dependent property
CIMTYPE'ref:CIM_LogicalDevice'
Description'The CIM_LogicalDevice dependent reference represents the CIM_LogicalDevice connected to the 1394 controller.'
keyTrue
MappingStrings['CIM|CIM_LogicalDevice']
Override'Dependent'
readTrue
Dependent property is in 103 classes of ROOT\cimv2 and in 15 namespaces
NegotiatedDataWidth property
CIMTYPE'uint32'
Description'When several bus and/or connection data widths are possible, the NegotiatedDataWidth 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/important to device management, the property should be set to 0.'
readTrue
Units'bits'
NegotiatedDataWidth property is in 12 classes of ROOT\cimv2 and in 3 namespaces
NegotiatedSpeed property
CIMTYPE'uint64'
Description'When several bus and/or connection speeds are possible, the NegotiatedSpeed property defines the one in use 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/important to device management, the property should be set to 0.'
readTrue
Units'bits per second'
NegotiatedSpeed property is in 12 classes of ROOT\cimv2 and in 3 namespaces
NumberOfHardResets property
CIMTYPE'uint32'
Description'Number of hard resets issued by the controller. A hard reset returns the device to its initialization or 'boot-up' state. All internal device state information and data are lost.'
readTrue
NumberOfHardResets property is in 11 classes of ROOT\cimv2 and in 3 namespaces
NumberOfSoftResets property
CIMTYPE'uint32'
Description'Number of soft resets issued by the controller. A soft reset does not completely clear current device state and/or data. Exact semantics are dependent on the device, and on the protocols and mechanisms used to communicate to it.'
readTrue
NumberOfSoftResets property is in 11 classes of ROOT\cimv2 and in 3 namespaces
