Using Drivers In Labview
LabVIEW 2014 Help Edition Date: June 2014 Part Number: 371361L-01 » An instrument driver is a set of high-level functions that control and communicate with instrument hardware in a system. In LabVIEW, an instrument driver is a set of VIs that communicate with an instrument using LabVIEW built-in VISA I/O functions. Each VI corresponds to a programmatic operation, such as configuring, reading from, writing to, and triggering an instrument. 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.
You also can. The contains instrument drivers for a variety of programmable instruments that use the GPIB, Ethernet, serial, and other interfaces. You also can search for National Instruments drivers at on the National Instruments Web site. You can use an instrument driver for a particular instrument as is. However, LabVIEW Plug and Play instrument drivers are distributed with their block diagram source code, so you can customize them for a specific application. You can create instrument control applications and systems by programmatically linking instrument driver VIs on the block diagram. Use the to search for and install LabVIEW Plug and Play instrument drivers without leaving the LabVIEW development environment.

LabVIEW instrument drivers usually use VISA functions to communicate with instruments. You can use VISA for many different instrument types, such as GPIB, serial, USB, LXI, PXI, and VXI. Once you learn how to use VISA for one type of instrument, you do not have to learn a different way to communicate when you use another type of instrument. You do have to learn about the specific command set for the two instruments, but the method by which you send and receive the commands does not change. Note You can use the to communicate with message-based instruments and graphically parse the response. NI provides more than 8,000 instrument drivers from more than 275 vendors.

Brooks Instrument Model GF40 MFCs (qty 4) with Multi-drop Cables LabVIEW™, a National Instruments software development tool, is widely used to create software applications that monitor and control a variety of sensors and control devices. It is very common to find a laboratory, university, or a pilot manufacturing plant using one of these applications to interface with mass flow devices. LabVIEW™ software can interface with a mass flow device through different forms of data acquisition. The most popular forms of data acquisition used with Brooks Instrument mass flow devices are described below. Analog Signal Interface Power Supply by National Instruments The chances are good that LabVIEW™ software users have analog to digital I/O cards, and can run their MFCs utilizing the 0-5 volt or 4-20 mA analog signaling via LabVIEW™.
Using IVI Drivers in LabVIEW5 ratings 3.60 out of 5 Read in Print Overview This document is intended for LabVIEW test developer. How to: Use from LabVIEW. When LabVIEW is restarted, the driver will appear on the Instrument Drivers palette. Using the RMCLink LabVIEW Examples.
This is recommended for anyone who may not be ready to move to direct digital control. RS485 Digital Signal Interface Brooks Instrument mass flow devices configured with the ‘S' communications option provide RS485 digital communications via the 15-pin D connector. The RS485 digital signal can be passed directly to the computer running LabVIEW™ through a serial RS485 converter. The, and from Brooks Instrument can be configured with the ‘S' communications option.
• Brooks Instrument provides a via our website which can be loaded directly into the LabVIEW™ application, and provide the building blocks for creating a LabVIEW™ software control interface utilizing the S-Protocol digital command structure. Additionally, a is included so these building blocks can be referenced and used within a LabVIEW™ application program interface (API). • Another possibility is to use the as an alternate tool to create links between the LabVIEW™ application and the GF40, GF80 or SLA Series flow, control, and configuration parameters. Additionally, the user can leverage Windows applications (Excel, Word, Access) and programming languages ( C++, C#, Visual Basic) and SCADA programs from suppliers such as Allesco and Millennium Systems International. No knowledge of the mass flow device S-Protocol command structure is required. With Smart DDE, the user gets direct access to the required data fields. This is not a 100% turnkey solution, but reduces the amount of coding required to communicate with and control the MFC.
DeviceNet Digital Signal Interface GF40, GF80 and SLA devices configured for DeviceNet digital communications can also be controlled via the LabVIEW™ application. Note that this requires a National Instruments DeviceNet interface card and associated drivers and software, which provide support for developing application interfaces using LabVIEW™ software for Windows and LabVIEW™ Real-Time. The following is taken from the website: National Instruments DeviceNet for Control interfaces are for applications that manage and control other DeviceNet devices on the network. These interfaces, offered in one-port versions for PCI and PXI, provide full master (scanner) functionality to DeviceNet networks. All NI DeviceNet interfaces include the NI-Industrial Communications for DeviceNet driver software, which features easy access to device data and streamlined explicit messaging.

Use a real-time controller such as PXI and NI industrial controllers to create deterministic control applications with the NI LabVIEW Real-Time Module. So, don't be afraid to go digital. The digital aspect of our mass flow devices include many on-board functions that work in the background and make the device superior even if the final flow signal is sent via analog signal (0-5 Vdc or 4-20 mA).
