Section Five - IBIC
The IEEE-488 Bus Interactive Control program ( IBIC ) allows you to
control and communicate with the GPIB through functions you enter at
the keyboard. This feature helps you establish communication with the
device, troubleshoot problems, and develop the application.
IBIC functions include most of the GPIB-PC functions described in
Sections Three and Four, plus auxiliary functions used only by IBIC .
In IBIC , the user can send data and GPIB commands to a device from
the keyboard and display data on the screen received from a device.
After each GPIB-PC function is executed, the numeric value and
mnemonic representation of the status word
IBSTA is displayed. The
byte count IBCNT and error code IBERR are also shown when
appropriate.
This interactive method of data input and data/status output is designed
to help you learn how to use the GPIB-PC functions to program your
device. Once you develop a sequence of steps that works successfully
for your system, you can easily incorporate the sequence into an
application program using the appropriate language and syntax
described in Section Four.
