Instrument Driver Organization Once an instrument driver has been downloaded, the instrument driver VIs will be located on the Instrument Drivers palette. These VIs include the majority of the instrument driver template VIs, such as reset, self-test, revision, error query, and error message. Get acquainted with sub-vi’s. Launch the software Initialize the A Place the A in 4W-resistance measurement mode Switch the A to “local” mode so that the end user can adjust a trimpot until the desired resistance is obtained while seeing the resistance value change on the A Re-initialize the A when I need to switch to a different measurement Alternatively, is there a way to get the A to continuously display whatever measurement it’s taking while in remote mode? Both of these drives are supported by Agilent and come complete with example code for common tasks. LabVIEW instrument drivers simplify instrument control and reduce test program development time by eliminating the need for you to learn the complex, low-level programming commands for each instrument.

The Action VIs – initiate or terminate test and measurement operations, such as arming the trigger system or generating a stimulus. Rate this document Select a Rating 1 – Poor 2 3 4 5 – Excellent. Message 5 of 6. The Status VIs obtain the current status of the instrument or the status of pending operations.
Many thanks for the help. The alternative to using the NI Instrument Driver Finder is to go directly to the Instrument Driver Network and search for your instrument driver there.

The Close VI- terminates the software connection to the instrument and frees system resources. Open a blank vi. Message 7 of 7. No offense was taken. I hope not to offend NI people http: Message 3 of 7. I added h to the picture below for ONE method of logging until a specified time. Finally, the Simple Error Handler is called which indicates whether an error occurred.

The Data VIs- transfer data to or from the instrument.

Message 6 of 6. Usually the drivers are accessible and you will see all the GPIB calls that are made by the driver.
Message 2 of 4. Yes you can do this, but in principle you are writing your own driver. You can create instrument control applications and systems by programmatically linking instrument driver VIs on the block diagram. Most instrument drivers have menu palettes that include the following components. You can use an instrument driver for a particular instrument as is.

I apologize if I offended you. Klomp 1, 1 7 In this example, serial communication is used.
