GPIB Programming Interface Examples
GPIB Function Statements (Command Messages)
Function statements are the basis for GPIB programming and instrument control. These function
statements, combined with SCPI, provide management and data communication for the GPIB interface
and the signal generator.
This section describes functions used by different IO libraries. For more information, refer to the
NI-488.2 Function Reference Manual for Windows, Agilent Standard Instrument Control Library
reference manual, and Microsoft Visual C++ 6.0 documentation.
Abort Function
The HP Basic function ABORT and the other listed IO library functions terminate listener/talker
activity on the GPIB and prepare the signal generator to receive a new command from the computer.
Typically, this is an initialization command used to place the GPIB in a known starting condition.
Remote Function
The HP Basic function REMOTE and the other listed IO library functions change the signal generator
from local operation to remote operation. In remote operation, the front panel keys are disabled
except for the Local key and the line power switch. Pressing the Local key restores manual operation.
Library Function Statement Initialization Command
HP Basic The ABORT function stops all GPIB activity. 10 ABORT 7
VISA Library In VISA, the viTerminate command requests a VISA session
to terminate normal execution of an asynchronous operation.
The parameter list describes the session and job id.
viTerminate (parameter list)
NI-488.2 The NI-488.2 library function aborts any asynchronous read,
write, or command operation that is in progress. The
parameter ud is the interface or device descriptor.
ibstop(int ud)
SICL The Agilent SICL function aborts any command currently
executing with the session id. This function is supported
with C/C++ on Windows 3.1 and Series 700 HP-UX.
iabort (id)
Library Function Statement Initialization Command
HP Basic The REMOTE 719 function disables the front panel operation
of all keys with the exception of the Local key.
10 REMOTE 719
VISA Library The VISA library, at this time, does not have a similar
command.
N/A
NI-488.2 The NI-488.2 library function asserts the Remote Enable
(REN) GPIB line. All devices listed in the parameter list are
put into a listen-active state although no indication is
generated by the signal generator. The parameter list
describes the interface or device descriptor.
