GPIB Command Statements

Command statements form the nucleus of GPIB programming; they are understood by all

instruments in the network. When combined with the programming language codes, they

provide all management and data communication instructions for the system.

An explanation of the fundamental command statements follows. Some computers may use

a slightly different terminology, or support an extended or enhanced version of these

commands. Use the following explanations as a starting point and refer to the HP BASIC

language reference manual, the I/O programming guide, and the GPIB manual for the

computer you are using.

Syntax drawings accompany each statement. All items enclosed by a circle or oval are

computer-specific terms that must be entered exactly as described; items enclosed in a

rectangular box are names of parameters used in the statement; and the arrows indicate a

path that generates a valid combination of statement elements.

The seven fundamental command statements are as follows:

Abort

ABORT abruptly terminates all listener/talker activity on the interface bus, and prepares

all instruments to receive a new command from the controller. Typically, this is an

initialization command used to place the bus in a known starting condition. The syntax is:

where the interface select code is the computer’s GPIB I/O port, which is typically port 7.

A BASIC Example

10 ABORT 7

100 IF V>20 THEN ABORT 7
