Re: Do I need LabVIEW RT for a simple 10objects/sec image acquisition/processing?

2004-06-18 Thread unclebump
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.

Re: Is it possible to use a second network card for Labview

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.

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'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

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

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.

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 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.

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
