No, I can't explain it. Right away anyway. Is it a bug? Well, it looks like
it may be a good candidate. For Count to 100,
charToInt(strFromLen(SimpleSort[a].SortName, 0, 1)) produces 100 0s though.

All the changes are pretty much confined to SICL, so as long as the new card
is at the same address as the old one everything will work out fairly well.
Interface ops may need tweaking.

Hmmm... yes I do remember something about that, but I think you might be
able to fudge it somehow. I have a machine happily running an NI card at 7
though it's not through I/O Libs.

Les or Jay should know for sure.

Turns out I am getting a little rusty on VEE. We haven't had a VEE contract
that has stretched us for awhile. The problem is that VEE has never done
the logical thing with I/O. Their I/O preceeded the development of the I/O
libraries, so they have always had a glue layer that limits and changes
capabilities. For example, direct USB connections have been included in the
Agilent Libraries since M.01.00, but I got burned by saying they were
available in VEE at that time. It required adding paths within the VEE I/O
layer that would connect to SICL.

The reason I mention that is that in M.01, the I/O libraries added features
so that the NI VISA could come co-exist with the Agilent VISA. Either one
can be the primary. This works well for VXIplug&play drivers, because they
use VISA. That way, an NI card can be easily substituted and the same
resource name applied (i.e. gpib1).

However, VEE still uses SICL for Agilent cards, and NI-GPIB for NI cards.
Thus the changes in major number. They are using the 7 and 14 to select the
driver to use.

I really don't see a foolproof method for changing cards on an arbitrary VEE
program. The biggest killer would be any direct I/O blocks that used
interface session commands, such as LOCAL 7. If you avoided that, some of
the tricks described by other posters should work.

The easiest thing would be to use plug&play drivers, including the generic
one that simpply allows command passthrough. Then the I/O becomes
transparent and totally handled by the I/O libraries configuration manager,
which is how it really should be done for everything.

For being rusty Jay remembers quite a bit.

Like he said, direct I/O is the biggest problem - Plug&Play will use VISA
and you can set the VISA addresses (GPIBn format) to match when changing the
system.

With direct I/O you must go into VEE's I/O Instrument Manager Properties and
change the card address. With VEE 7 you can easily change GPIB to LAN or
USB as well as changing the card number. (Just did that last week - big
time saver.)

Hi, all!

It is possible to develop a VEE program that allows one to change GPIB cards
(Agilent <-> NI). I have got several such programs. There is only one term,
it is necessary do design auto config function. I have in mind that at first
step searching GPIB devices is executed. Then by means of parsing *IDN?
responce actual GPIB address of each device is found. It is obvious that
object like IO.newInstrument9.address = value allows one to set actual GPIB
address for each instruments.

This aproach does not work if there is need in using TCPIP imstruments
without predefining IP address or computer name, since both Agilent and NI
do not offer a way how to discovery TCPIP instruments that are present in
local NET in run time.

With best regards,

Mikhail Kozlov

Subject: [vrf] Re: GPIB replacement without modifying VEE source code

Thanks.... What I am trying to do was that NOT modifying any part VEE
code(assuming the application software is VEE Runtime one and the
communication was done with DirectIO.) and replace GPIB card with the
other one.

It seems it is not possible replacing GPIBs directly without
modification of VEE source code.

According to page# 214 of VEE Pro Advanced Programming Techniques, "only
local units 14,15,17 and 18 are supported for National GPIB cards on the
PC".

However, those were "Recommended" ones on page# 213.

JC Park

Barrie,

I would use an interface event, check the advanced i/o to make the correct
choice. After the event is triggered, I would store the data into a global
string, that is do the read, and make any necessary calls and reset. If
your i/o does not allow an interface event, an on-cycle will work, but
you'll need to set the flag.

There are other ways of handling the event, but you choose what you need.
Note, the reason I used a global, is to make the data available to all. You
might not want this. I prefer to use a global record. Within the global
record I place a location to store received strings. Any routine may do a
read and reset of the string. This way I am able to respond wherever I am
within the code.

So you have a couple of choices:

1. Respond as soon as you receive the data
2. Check periodically, using an on cycle, for new data added to the string.
Easy if you set a flag.
3. Have specific locations within the code to check and respond.

The last is tricky if running "stuff" can't be interrupted.

Subject: [vrf] Joystick control

Hi Folks,

I want to test an underwater vehicle using a joystick. At present I have a
Vee application that controls the vehicle but it requires mouse movement and
button clicks. This approach is too slow and requires the operator to take
his/her eyes off the vehicle (its a little too early in the development
process to let that happen frequently). So, I purchased a simple game
controller joystick that includes some interface customization software (its
a USB device, not RS232). At first I thought it would be simple to
interface the joystick input to my Vee application but this doesn't seem to
be the case. The joystick can be programmed to output ASCII text in
response to its various motions and button presses. This text appears to be
what an application would receive from a keyboard entry and I can see it
using WordPad or similar terminal emulation software. A Vee text box can
also receive it and if the joystick output string contains a <cr> the text
box fires and passes the input to other objects - so far so good.
Unfortunately, the text box has now lost focus which means any additional
input from the joystick will be ignored.

Basically, I'm looking for a method to allow an application user to
continuously enter characters from a keybd (or equivalent) and have them
evaluated and acted upon each time a carriage return is entered. Sounds easy
but....

I have an alternative but it has a similar problem: I could try controlling
the vehicle with a portable mouse-like device. This would require an
interface between the mouse driver and my Vee application (and the normal
mouse responses would need to be disabled). Has anybody ever tried anything
like this?

Any thoughts or suggestions welcomed.

Barrie

Thanks.... What I am trying to do was that NOT modifying any part VEE
code(assuming the application software is VEE Runtime one and the
communication was done with DirectIO.) and replace GPIB card with the
other one.

It seems it is not possible replacing GPIBs directly without
modification of VEE source code.

According to page# 214 of VEE Pro Advanced Programming Techniques, "only
local units 14,15,17 and 18 are supported for National GPIB cards on the
PC".

However, those were "Recommended" ones on page# 213.

Changing the address (select code) in the VEE -> Instrument Manager
should mostly work.

Example: Change address 714 to 1414.

In this case you could define the instuments as "NOT LIVE"

Live Mode -> OFF or Address -> 0

and then programatically set the addresses.

You misunderstood what I said before. I don't do this in run time. I do it
while VEE is stopped.

Ah and here's another point: The host OS is Linux, and the emulator is
running Windows. If the emulator is truly emulating NT's IO schema, it seems
to me you'd need both the Windows and Linux drivers? Or will the emulator be
able to make Linux transparent & access the hardware directly? It seems to
me that would violate at least a couple rules.

I'm pretty clueless about emulation at this point. I've seen DOS & Windows
emulators run on a Mac years ago & I have the Mame32 source, but I still
don't know much about it.

Very sensible.

Well you never know till you ask! You'd think that given all the hassle to
get VEE running it would be easier to simply write your test system with C++
for Linux in the first place.

Hello Les Hammer,

would you, please, define more exactly how you change GPIB direct I/O to LAN
direct I/O in run time?

Agilent support claims that there is no way to do such a thing. It is
impossible to submit VISA address to GPIB direct I/O object since VEE7 GPIB
direct I/O object uses SICL library or direct NI GPIB call. As well as
impossible to submit VISA address like GPIB0::14::INSTR to LAN direct I/O
object.

With best regards,

Mikhail Kozlov

For being rusty Jay remembers quite a bit.

Like he said, direct I/O is the biggest problem - Plug&Play will use VISA
and you can set the VISA addresses (GPIBn format) to match when changing the
system.

With direct I/O you must go into VEE's I/O Instrument Manager Properties and
change the card address. With VEE 7 you can easily change GPIB to LAN or
USB as well as changing the card number. (Just did that last week - big
time saver.)

What I have done is to NOT save the IO with my VEE programs
but rather keep it as an external IO file. Then to change stuff
like this I need only modify the file with a text editor.

A simple startup script selecting which IO file is to be used
( like Agilent vs NI) and running VEE using that IO takes
care of the portability.

This way the VEE code doesn't have to change and no manual tweaks
are needed.
