An explanation on how to use Pickering's drivers in National Instruments LabVIEW, with graphical examples for different types of drivers. The IVI configuration utility in MAX configures a driver session to store the settings you want to use. This method uses the standard Initialize VI that you use with traditional LabVIEW drivers. To make your program use the configured settings, you pass the name of the configured driver session to the resource name control of the Initialize VI.
The IVI Engine always defines measurement parameters consistently, and the instrument driver adjusts parameters to account for differences between individual instruments. IVI drivers give you features that do not exist in traditional instrument drivers. To enable one of the IVI features, you set its value to 1 in the option string. You have successfully completed all sections and learned how to configure an IVI system in MAX, run a sample program in the simulation mode, and interchange instruments. IVI drivers verify that the values you specify for an attribute are valid. This is typically the first interface in the list.

Because Plug and Play drivers maintain a common architecture and interface, you quickly and easily connect to and labview ivi with your instruments with very little or no code development.
You can configure IVI drivers settings independently of a test application. Instrument drivers are an indispensable tool to help you rapidly develop labview ivi and measurement applications. IVI drivers give you features that do not exist in traditional instrument drivers.
This site uses labview ivi to offer you a better browsing experience. Click Go To to view the properties of the hpa driver session.
Dottable properties have a blue glyph next to labview ivi property labview ivi. Instrument drivers simplify instrument control and reduce test program development time by eliminating the need to learn the programming protocol for each instrument.
Converting vii data to an array See Also: To disable a feature, you set its value to 0. An example of how to access the help for the Initialize method is shown in Figure 9.
What is IVI? – National Instruments
Each routine corresponds to a programmatic operation such as configuring, reading from, writing to, and triggering the instrument. An labview ivi reported from status checking does not invalidate the cached state of the instrument. Select fl45 from Driver Session as shown in the following figure.
Labview ivi you have a standard interface to instrument drivers, you can work more quickly because you do not need to learn a new interface for each new instrument.

Labview ivi dotted properties and methods. IVI drivers verify that the values you specify for an attribute are valid.
See All Countries and Regions. Kabview dialog box appears, shown labview ivi Figure 1. If you do not have the actual instrument connected to your system, make kabview that you select Specific Driver in the Simulate With drop-down.
If you enable Record Value Coercions and never use Get Next Coercion Record VI to retrieve and clear those coercion records, the records build up and could eventually overflow your labview ivi memory.
For example, if an oscilloscope is connected to your PC through the GPIB bus labview ivi an address of 2you can use either of the following approaches:.
They point to driver sessions and labview ivi for interchangeability. For instrument drivers that support a family of instruments, you can also use the option string to set the particular model ivj instrument that you want the driver to emulate.
Therefore, you will generate errors if you attempt to use both labview ivi. Simulation mode provides the benefits shown in Table 1. This app note cannot be implimented because the version of MAX referenced is obsolete.
Getting Started Using National Instruments IVI with LabVIEW or LabWindows/CVI
This technique burdens you with inserting error-query VIs throughout the application to verify operation at various stages. You can use Logical Names at class-driver level and can also be used at the specific-driver labview ivi. To enable one of the IVI features, you set its value to 1 in the option labview ivi.
labview ivi Select the same type library you selected for the Automation Open refnum. Certified Plug and Play instrument drivers are technically supported by National Instruments, while Plug and Play instrument drivers are supported by instrument vendors or other third parties. In IVI drivers, an attribute represents each area that you can configure in an instrument.
You can download these resources from ni. Simulation Tools and Soft Front Panels In addition to the class drivers, the IVI Driver Library includes simulation drivers for labview ivi class, so programmers can develop test programs when the instruments are not available. The IVI Engine always defines measurement parameters consistently, and the instrument driver adjusts parameters to account labview ivi differences between individual instruments.
Introduction Instrument drivers—software modules that control programmable instruments—have advanced technologically in many ways.
