Example: GPIB Interface Configuration
An I/O interface consists of a hardware interface and a
software interface. One purpose of the Connection Expert
utility is to associate a unique software interface ID with a
hardware interface. The Agilent IO Libraries Suite uses an
Interface ID or Logical Unit Number to identify an interface.
This information is passed in the parameter string of the
viOpen function call in a VISA program or in the iopen function
call in a SICL program.
For example, the GPIB interface system in Figure 1-14 consists
of a Windows PC with two 82350B GPIB cards connected to
three GPIB instruments via GPIB cables. For this system, the
Connection Expert utility has been used to assign GPIB card
#1 a VISA interface ID of “GPIB0” and a SICL interface ID
of “gpib0”.
Connection Expert has also been used to assign GPIB card #2
a VISA interface ID of “GPIB1” and a SICL interface ID of
“gpib1”. With these names assigned to the interfaces, the
VISA/SICL addressing is as shown in the figure. Since unique
names have been assigned by Connection Expert, you can use
the VISA viOpen command to open the I/O paths to the GPIB
instruments. Or, you can use the SICL iopen command to open
the I/O paths shown.
