Owning Palette: Instrument I/O VIs and Functions

Use the GPIB functions to communicate with GPIB (IEEE-488) devices.

The functions on this palette can return specific GPIB error codes.

Compatible GPIB Hardware

All NI-488.2 hardware drivers are compatible with LabVIEW. Refer to the GPIB Troubleshooting Resources on the Web for information about current driver versions for each GPIB controller.

Palette Object	Description
GPIB Clear	Sends either SDC (Selected Device Clear) or DCL (Device Clear).
GPIB Initialization	Configures the GPIB interface at address string.
GPIB Misc	Performs the GPIB operation indicated by command string. Use this low-level function when the other high-level, traditional GPIB functions are not suitable.
GPIB Read	Reads byte count number of bytes from the GPIB device at address string.
GPIB Serial Poll	Performs a serial poll of the device indicated by address string.
GPIB Status	Shows the present status of the GPIB Controller indicated by address string. Error I/O operates uniquely in this function. The function gets the status of the GPIB Controller regardless of whether an error occurred in a preceding operation.
GPIB Trigger	Sends GET (Group Execute Trigger) to the device indicated by address string.
GPIB Wait	Waits for the state(s) indicated by wait state vector at the device indicated by address string.
GPIB Write	Writes data to the GPIB device identified by address string.
Wait for GPIB RQS	Waits for the device indicated by address string to assert RQS.

Subpalette	Description
GPIB 488.2 Functions	Use the GPIB 488.2 functions to exchange data and instructions between VIs and GPIB 488.2 devices.
