With the 6503 you can use DAQmx and the assistant. I would suggest
first of all Going into MAX and setting up your channels in there. See
Manual or help. Or you can use the assistant to do this for you. Drop
the assistant onto the block diagram and let it come up then select
digital I/O. from
Thanks for clearing up my mistake. Kura Altenbach is correct. After
reading your question again I realize I was wrong. sorry for that,
thanks again altenbach.
Make case 1 the default case then right click on the tunnel and select

Hope this helps

The base version is just as the name implies. You would be better off
if you chose the full developemet edition of labview 7.1(current
version) This will give you all the functionality of the base version
plus a lot more features. Some you may not need NOW but will become
valuable in the future as
This is very easy to do in labview.The way that you do it is by double
clicking the control. This will bring up the customize window and from
there you can make it look like you want it to by inserting pictures
into the control of the way you want it to look at each state. Look at
the shipping
You may want to call NI about certain questions. Call your Local NI
representative and talk to them. You may try downloading the
evaluation version of labview 7.1.
Sorry I cannot help more.
I have used this trick alot. One thing that I found is that if you
make the color inside the graph white instead of transparent you will
get the results that you are looking for. I usually make the outside
of my graph transparent and the inside of my graph white and it looks
good.
Hope this helps
Thanks for all your help. I'm Not that great with IO. It works just
like you said. So now all I have to do is create a task then write
zero's to it at the beginning of my program. then it should work
correctly right.
thanks
Joe
I got this work with mpg, mp3, and wav files. what version of labview
and windows are you running.
What you need to is write a configuration file. There is a shipping
example on how to do this called write configuration settings file.
Joe
Thank you Dennis for makung labview a fun language instead of a
frustrating one.
late nights, lots of coffee, then in the morning ask dennis then have
it fixed by noon and the boss loves YA.
Thanks again Dennis you are an inspiration to all of us.
I have A PC-DIO-96 card and my dilema is that when I write all outputs
low and then try to read them back The outputs read High. Why is that?
what you need to do is open your main application right click on the
VI in question and select SubVI node setup check the box for open when
called and close afterwards if originally closed. this is one method.
The other method is open the subvi in question go to Vi properties/
window appearance/
what you will have to do is give each instrument a diiferent address.
See owners manual for this and then adjust your code accordingly
instrument 1 = GPIB::0
instrument 2 = GPIB::1
you can do this up to 16 instruments.
There are also some good shipping examples for using GPIB
Hope this helps
That is a neat little Vi.
Cool
They do not have to be used together.
To explain further lets say you have created a VI to be used as a
subvi in a main app. You may want that subvi to be called when you
press a button and this vi will always open its front panel. In this
instance you would use method two.
Now lets say that you
Can you please post your Vi's saved in version 7.0 To do that all you
have to do is go to file/save with options/save for previous.Do this
and I will have a look to see what might be wrong.
Thanks
It is hard to explain what you may be doing wrong without seeing your
code. Please post your code and let us have a look a it.
Just my 2 cents put you would benefit with upgrading to nothing less
than 7.0 but why not go 7.1 If this is an option do it. DAQmx
Assistant alone will save hours of design time. Not to mention all the
other math functions now available with 7.1
Joe
also one other thing if this is already an executable does it work in
design time. It sounds to me like there may not be any wait functions
in any of the loops which will cause the cpu usage to max out.
right click on the graph. go to properties/plots tab then in name
field type the name you want that plot to have.
hope this helps
Joe
Sweet VI Good job. how did you get the ref to the block diagram. I
have been looking for it.
Just be sure to save it as a different name.
Glad to help
Joe
yea this is very easily done.But you cannot just do a simple import
but what you can do is open the picture that you want to put on the
panel. Select it(edit, copy) then go to the front panel of your VI and
paste it in. Then you can resize it as needed.
Hope this helps.

2.Right click on VI and select open front panel, then select convert

The easiest way to do that is to use the event structure (7.0). and
edit the events of the structure to handle the OK button. If you do
not have a version of labview that has the event structure capability,
then you can use a statemachine. Look at the examples for further
info. I'll try to attach
tell me what you would like to do with it and I will help you. Do a
search on activeX in the examples and you will find how to do it with
activeX.

there is no need to do polling if he uses the event structure. Polling
takes up processor the event structure, saves processor time for
something else because it waits for that one event to happen. I agree
event structure is probably overkill but it is easy to learn how to
use and will let
As an answer you can download the openG toolkit from www.openG.org and
there is a tool in there that will this.
I have ran into this during other time critical data acquisitions
within a loop using win2K and found that if I put a wait function in a
loop with 0mS it works just fine if I move the mouse.
Sorry cannot help more
One of the easiest ways would be to use the VI server. There are many
examples on how to do this that come with labview.(7.0) Do a search on
server and you will find many ways.
Joe
Please repost your VI. Second any of the filter Vi's should work.
I'm pretty sure that you cannot install on multiple machines at your
company at any one time. Even though you have purchased the upgrades
for 6.1 and 7.0 you still fall under the same agreement that was
initially purchased for 6.0. However if these are not upgrades then
you can. Also under the
If I remember correctly that when you expand the index array and do
wire a any constants to it then it will automatically do this for you.
Check the help and see.
Joe
Are you wanting to know how many times that your pulses cross a
certain value after the index array or are you wanting to know how
many times before index.
where exactly are you trying to count the pulses. if after the index
then are you saying that as long as it is between the upper and lower
when you built the dll di you make it reentrant. if not this could
possibly cause what you are seeing.
My advice would be to definetly do all the calculations outside of the
loop.Also you will want to use double buffering if you can. I'm not
sure if that card will do that or not.what the AI C scan uses is a
circular buffer which means if you do not read the data fast enough
then you will get buffer

it's just a property node. like if you were to run a macro then look
at the code for it. this is what it would look like. Just do what A
rafiq said and you'll be fine.
I think now they have this fixed with 7.0. I do know that there was a
bug. here is a link. hope it helps

The easiest way to do that would be to use a picture ring and modify
the bitmap image for all the stages that you would need and place them
into the picture ring and update the ring for each case.
help us understand your question.
Do you mean that you want it to check various things on start up (ie
monitor pluged etc) or what type of self test are you talking about.
Please be more specific
I just contacted NI on this matter. The VI analyzer is an add on
toolkit that is not available with any other toolset. Meaning it must
be purchased separately. TN's company must have purchased it
separately for him without him knowing it.If you have any questions
about this contact NI sales.

What are you trying to do with the file. Play or just read it into
your vi so that you can manipulate the data.
it is no problem to play the data using active x and windows media
player
Be more specific so I can help you further.
I'm assuming that you mean that when you delete that token that when
the I/O assistant recompiles that you do not want to have to rewire
your whole code. with that being said there is no way around that
happening. but there is a work around. What you need to do is leave
your code wired they way

Labview will do this very nicely. Although you could do this with a

so try this method.

HI mudda
This will probably sound a little crazy but if you are not putting in
some type of wait function into your loop then you could be seding you
processor to 100% therefore slowing down the process. this will free
upi some processor time. i do this in all my applications because it

this is where you put the path to the main VI.
like this dstp://localhost/mainvi. where MainVI is the name of your
application that is calling the subvi. you must start this path with
dstp.
you must have the data socket server open and running before you start
running the main VI. if you do not it will appear that the VI does not
work correctly. Again read up on the data socket server before running
the VI again. If this still does not work write back and I will try to
