Select the same type library you selected for the Automation Open refnum. Refer to the instrument driver help to determine the array data type. Each VI corresponds to a programmatic operation, such as configuring, reading from, writing to, and triggering an instrument. Instrument drivers simplify instrument control and reduce test program development time by eliminating the need to learn the programming protocol for each instrument. Generally, you need to call the Initialize VI only once at the beginning of an application.

I hope not to offend NI people http: Examples include VIs for reading a measured value or waveform and VIs for downloading waveforms or digital patterns to a source instrument.

You can use an instrument driver for a particular instrument as lavbiew. They also have a CVI driver that can be converted. You also labvoew use the Instrument Driver Finder to open example programs covering everything from analysis and presentation to using your instrument driver.

In the following figure we have opened the Agilent Read Multiple Measurements. Then the Configure Measurement VI is called to set the instrument up for the desired measurement.

Dotted properties are a shorthand alternative to cascading multiple Property Nodes that return interface references needed for wiring properties and methods specific to a given interface. Overview of Instrument Drivers An instrument driver is a set of software routines that control a programmable instrument. I’m not sure about instructions, but if you installed the driver and opened the library, you will agilenf sub-vi’s which have a particular application purpose.

You should close references to all ActiveX sessions and interfaces when you are finished using them.

Selecting a dotted property. Viewing context help for AutoRange property. Saying that it is straight forward is not what you want to read, right? Soon, you’ll combine them into your own vi and you’ll prefer using the multimeter through Labview rather than pressing the buttons. Rate this document Select a Rating 1 – Poor 2 3 4 5 – Excellent.

agielnt Message 7 of 7. The block diagram should now appear similar to Figure 2. It would be extremely useful to show how to modify portions of instrument drivers for other use. A dialog box appears, shown in Figure 1.

Links to complete examples demonstrating how to execute the Measurement method and read the measured value are provided at the end of this document. I hope this helps!

Your on your way to success Hope this helps. Additionally, it can perform any necessary actions to place the instrument in its default power on state or in another specific state. The Initialize VI- the first instrument driver Labvview you call, establishes communication with the instrument.

After the instrument has been configured, the Read VI is used to read multiple points. Figure 10 shows the Context Help window for the AutoRange property. The Utility VIs might also include other custom instrument driver VIs that perform operations agilemt as calibration or storage and recall of setups.

Many instrument drivers have a VI Tree VI you can use to view the entire instrument driver hierarchy.

Don’t be afraid of experimenting. When all of these settings are labvie and the VI is executed the results will be displayed in the Measurements array indicator.

The Action VIs – initiate or terminate test and measurement operations, such as arming the trigger system or generating a stimulus.
