In the correct display mode? How did you add cr and lf? Before buying a new instrument, you can install the IVI-specific driver for that particular instrument and run your test program. This approach to range checking eliminates incorrect settings and points out conflicts in an application. In contrast, IVI drivers use state caching to eliminate redundant commands. You do not need to use the class drivers to get this level of simulation.

The new technologies introduced with IVI drivers maintain the benefits of traditional drivers while adding features that improve the application development process and application performance. Do you send a cr lf in labview? This approach to range checking eliminates incorrect settings and points out conflicts in an application. Instrument specific VIs supplement the standard VIs and provide access to functions that are unique to the instrument.

This technique burdens you with inserting error-query VIs throughout the application to verify operation at various stages. There are three different levels of simulation: Instrument driver calls — The simplest form of simulation is the ability to make calls to an instrument driver when the instrument is not connected to the computer.

When you specify an attribute value, IVI drivers also identify dependencies for the attribute ranges on other instrument settings. If you labviea not have the actual instrument connected to your system, make sure that you select Specific Driver in the Simulate With drop-down.

Using IVI Drivers to Simulate Your Instrumentation Hardware in LabVIEW and LabWindows/CVI

Choose two IVI-C specific drivers to use in the examples. Rate this document Select a Rating 1 – Poor 2 3 4 5 – Excellent. Note that this is entirely the same when the ECHO labivew is off, except that step 2 does not occur. You can call the Oabview Next Coercion Record VI, which accesses the coercions by retrieving and clearing the oldest recorded instance.

You can also enable simulation through a configuration file without changing your program source code.

Two that come to mind are: I used the example found here: Often you choose an instrument setting from a range of values for example from lxbview. Therefore, instead of letting the instrument coerce the value, the IVI driver coerces the value before it sets the instrument.

Error checking includes consideration of rounding performed by specific instruments. When you are using the class driver, you can enable simulation through a configuration utility.

Message 10 of Most Active Hardware Boards: When using traditional instrument drivers, you have to supply some functions with the name of the channel that albview would like to configure or measure.

Therefore, if you are unfamiliar with instrument drivers, a particular function, or just want to test various values, you can run the function by clicking on the run button white arrow. With those drivers, high-level VIs might combine a number of instrument settings into a single VI.


Today, using current instrument driver technology, you cannot make a single labviea driver call from your program if the instrument is not connected.

Therefore, you do not have to have the instrument connected to the computer to perform range checking. Sets internal structure Sets programmatic interface of similar instruments Divides instruments into functional classes such as oscilloscopes and digital multimeters Establishes the characteristics of each class of instruments The IVI Foundation also specifies the programmatic interface for these different classes of instruments.

When you write test code without the instrument connected, the IVI driver still automatically ensures that each value you are attempting to send to the instrument is valid, even if it does not send the values to the instrument. The architecture is designed so users can add value with customized plug-in code.

You can find all of the following components on ni. You can download these resources from ni. State Caching IVI drivers maintain the physical state of instruments in a software cache to increase the efficiency and speed of instrument drivers. In effect, you can test a new instrument before you purchase it to make flhke it will work in your system.
