Do you have the signal processing toolset?? There is a denoise and
detrend vi that does some really neat processing on the data. Do you
have labview 7?? There is a math function express vi in it that does a
differential processing on the signal. This turns slope changes into
large spikes. Perhaps r
I ran into this same problem when using the database connectivity
toolset. On a win2000 machine, the .mdb file size was limited to 1GB.
I changed my DSC application to store the data in the CITADEL
database. CITADEL handles all of the file naming and size issues
internally.
I sent in a huge DSC application in response to a posting for the DSC
group. The link should get you to the files I submitted. It was my
first experience with Labview, so there should be a bunch of code
improvements in this one. It was a real battle to get high speed DSC
communication with OPC serv
I'll just have to use the get waveform component function to retrieve
the 'Y' array inside a for loop. and use a regular 2D graph inside the
cluster. Can you do mask and limit testing on array data directly
without converting into waveform?? Seems like a waste of memory having
to take an array of t
Try using the 'List Directory' command under the File I/O, Advanced
File Functions from the block diagram. This will output a list of
filenames in a directory. Then use the 'Array Size' function to see if
the directory is empty(array size >0). If true, then read you file. If
false, then do nothing.
Does Mitutoyo have a sample communication program that you can run on
your computer to test cabling, etc?? It may not give you the specific
data that you want, but knowing that you can talk to it will eliminate
many questions. The instrument assistant express vi's might be a good
place to start, bu
Here is a link to a third party Mitutoyo serial port program on the
NI site.

I write my cluster data as binary strings to tags that get stored in
the Citadel database. I had some issues with database file sizes being
too large to store months of data. I used Citadel because it handles
all of the file storage stuff internally. I would think NI will always
make future version
I would like to see what you have if possible. Could you send to

You can also multi-home a network card. You can assign up to ten ip
addresses to the same network card. I use this with modbus tcp
connections to several modicon momentum plc's. I am not sure if it
will work using different protocols at the same time.
You can do this with multiple while loops running in parallel. Acquire
the picture data in one loop and put it into a queue. Then use another
loop to analyze the picture data when something is in the queue. When
the queue is empty, this second loop will do nothing.
