bus The function addresses the interface indicated by bus as a Talker.
bus refers to the GPIB bus number. If you have only one GPIB interface in your computer, the default bus number is 0. Refer to the software installation instructions included with your GPIB board for additional GPIB interfaces.

address The function addresses the device indicated by address as a Listener.
If you do not wire address, the function sends data string with no addressing, thereby sending it to all previously addressed Listeners. To send data string to several devices, use the SendList function.
address contains the primary address of the GPIB device with which the function communicates. If a secondary address is required, use the MakeAddr function to put the primary and secondary addresses in the proper format. Unless specified otherwise, address and address list are data types integer and integer array, respectively.
The default primary address of the GPIB board is 0, with no secondary address. It is designated as System Controller. The default timeout value for the functions is 10 seconds. If you want to change any of these parameters, use the configuration utility included with your GPIB board. You also can use the GPIB Initialization and SetTimeOut functions to set the primary address and to change the default timeout value at run time, but these functions affect the interface only when you use it with LabVIEW. Refer to the documentation supplied with your hardware interface for more information.

mode describes how to signal the end of the data to the Listener.
0 | Do nothing to mark the end of the transfer (default). | 1 | Send NL (linefeed) with EOI after the data bytes. | 2 | Send EOI with the last data byte in the string. |
|
 |
data string contains the data bytes that the function sends to the GPIB device.

error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
 |
status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
|
 |
code is the error or warning code. The default is 0.
If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
|
 |
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
|
|
 |
status is a Boolean array in which each bit describes a state of the GPIB Controller.
If an error occurs, the GPIB function sets bit 15. GPIB error is valid only if bit 15 of status is set. Refer to the GPIB Status function for more information about status bits and GPIB error codes.
|
 |
byte count refers to the number of bytes that pass over the GPIB.
|
 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
 |
status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
|
 |
code is the error or warning code.
If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.

source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
