Inherent IVI Capabilities
Inherent IVI Capabilities are the functions and attributes that all IVI class drivers implement.
 | Note To complete the function names in the following table for any one of the IVI class drivers, replace ClassPrefix with one of the class prefixes: IviDmm, IviDCPwr, IviFgen, IviScope, or IviSwtch. For example, for the digital multimeter DMM class ClassPrefix Initialize VI becomes IviDmm Initialize VI in LabVIEW, and ClassPrefix_init becomes IviDMM_init in LabWindows/CVI. |
Use the following links to browse the tables, which show the inherent IVI VIs/functions and properties/attributes.

Inherent IVI VIs/Functions
| LabVIEW Inherent VI | LabWindows/CVI Inherent Function |
|---|---|
| Initialize/Close—Contains VIs and functions that initialize and close instrument driver sessions. | |
| ClassPrefix Initialize
ClassPrefix Initialize With Options ClassPrefix Close |
ClassPrefix_init
ClassPrefix_InitWithOptions ClassPrefix_close |
| Set, Get, and Check Attribute/Property—Contains VIs and functions that set, get, and check the values of attributes. Type-safe functions exist for each attribute data type. The possible data types are ViInt32, ViReal64, ViString, ViBoolean, and ViSession. You insert one of these values in place of the place holder, <type>. | |
| Use Property Node VI to get and
set attributes. You can not check attributes in LabVIEW.
ClassPrefix Invalidate All Attributes |
ClassPrefix_SetAttribute<type>
ClassPrefix_GetAttribute<type> ClassPrefix_CheckAttribute<type> ClassPrefix_InvalidateAllAttributes |
| Utility—VIs and functions that control common instrument operations. These functions include many of the functions that VXIplug&play requires, such as reset, self-test, revision query, error query, and error message. This class also contains functions that access IVI error information, access interchangeability warnings, access coercion records, and lock the instrument driver session. | |
|
ClassPrefix Reset
ClassPrefix Self-Test ClassPrefix Revision Query ClassPrefix Error-Query ClassPrefix Error Message ClassPrefix Reset With Defaults ClassPrefix Disable |
ClassPrefix_reset
ClassPrefix_self_test ClassPrefix_revision_query ClassPrefix_error_query ClassPrefix_error_message ClassPrefix_ResetWithDefaults ClassPrefix_Disable ClassPrefix_GetSpecificDriverCHandle |
| Error Info Subcategory | |
| Use the General Error Handler VI to view errors, which is the standard LabVIEW approach. | ClassPrefix_GetError
ClassPrefix_ClearError |
| Interchangeability Info Subcategory | |
| ClassPrefix Get Next Interchange Warning
ClassPrefix Reset Interchange Check ClassPrefix Clear Interchange Warnings |
ClassPrefix_GetNextInterchangeWarning
ClassPrefix_ResetInterchangeCheck ClassPrefix_ClearInterchangeWarnings |
| Coercion Info Subcategory | |
| ClassPrefix Get Next Coercion Record | ClassPrefix_GetNextCoercionRecord |
| Locking Subcategory | |
| You cannot lock IVI sessions in LabVIEW. | ClassPrefix_LockSession
ClassPrefix_UnlockSession |
|
Note Use VIs and properties when you configure IVI drivers in LabVIEW. Use functions and attributes when you configure IVI drivers in LabWindows/CVI. |
