HELP
Selects an I/O object to control an
instrument using an instrument driver where
all the panels are available.

USE
Click on I/O ==> Instrument and examine the
list of configured instruments in the Select
an I/O Device dialog box.

If the instrument you want is in the list
and is properly configured:

l.  Click once on the desired instrument
to highlight it.  (If the instrument is not
configured with an ID Filename, the State
Driver and Component Driver buttons are flat
(grayed)).

2.  Click the button at the bottom of the
dialog box labeled State Driver.

If the instrument you want is not in the
list or is not properly configured, use
Configure I/O to change the existing
instrument, then:

1.  Click on Add to add a new instrument.

2.  Complete the resulting dialog boxes.
Refer to the Configure I/O entry for details
about how to complete these dialog boxes.

All instruments must be configured before
they can be accessed by way of the
Instruments menu selection.  The best way to
configure instruments is to use the Configure
I/O menu selection.

Instrument objects may be operated with or
without live instruments connected to the
computer.  If you wish to control a live
instrument, you must set a correct, non-zero
address and enable Live Mode.  The address
and Live Mode setting are controlled by the
I/O ==> Configure I/O menu selection.  If the
address is zero or if Live Mode is off, the
instrument object operates but does not
attempt to communicate with a physical
instrument.

State drivers can be used interactively or
within a model.  To set the value of an
individual component, click on the field
containing the value of the component and
complete the resulting dialog box.  To make a
measurement and display the result, click on
the corresponding numeric readout or XY
display inside the State Driver open view.

It is possible to have more than one
object controlling a single instrument, that
is, two State Driver objects for "fgen" in
the same model.  These objects performs state
recalls when operated.

It is possible to add inputs and outputs
for the components inside the driver, similar
to Component Drivers.  Inputs perform the set
actions of the component, outputs perform the
get actions of the component.

Your system administrator must properly
configure your computer before it is possible
to communicate between HP VEE and any
hardware interface.  If you believe that you
have properly followed all HP VEE procedures
properly and you still cannot achieve any
level of communication with an instrument,
the problem may be with your computer
configuration.  Ask your system administrator
to read this explanation and verify proper
configuration of your system's interface
drivers.  (These interface drivers are
different from the instrument driver files
included with HP VEE.)

LOCATION
