Requires: Base Development System. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Instrument I/O VIs and functions to interface with GPIB, serial, modular, PXI, and other types of instruments. Use the NI Instrument Driver Finder to search for and install instrument drivers. If an instrument driver is not available in the NI Instrument Driver Finder, you can use the Create New Instrument Driver Project wizard to create a new instrument driver. If you do not find or create an instrument driver, you can use the Instrument I/O Assistant to communicate with message-based instruments.
If driver VIs you expected to find on this palette are missing, you must install support for the driver in the current version of LabVIEW.
| Note If you installed an instrument driver with a previous version of LabVIEW, you must reinstall that instrument driver with the current version of LabVIEW. |
Before you begin using the Instrument I/O VIs and functions, make sure you choose the appropriate method of instrument control.
| Subpalette | Description |
|---|---|
| GPIB Functions | Use the GPIB functions to communicate with GPIB (IEEE-488) devices. |
| Instrument Drivers VIs | Use Instrument Drivers VIs to configure, control, and retrieve data from GPIB, serial, modular, PXI, and other types of instruments. Use the NI Instrument Driver Finder to search for and install instrument drivers. If an instrument driver is not available, you can use the Create New Instrument Driver Project wizard to create a new instrument driver. If you do not create an instrument driver, you can use the Instrument I/O Assistant to communicate with message-based instruments. |
| Memory Access VIs | Use the Memory Access VIs to read and write values to specific memory address locations. |
| Serial Compatibility VIs | Use the Serial Compatibility VIs to interface with devices using serial communication.
The VIs on this palette can return serial compatibility error codes. |
| Serial VIs and Functions | Use the Serial VIs and functions to access the VISA VIs and functions that communicate with devices connected to a serial port. Additional functions are also available on the VISA palette. |
| VISA VIs and Functions | Use the VISA VIs and functions to program instruments using VISA. |
