• Error-307650 during a sequence in real-time with API LV

  I created a basic real-time sequence that checks the time it takes a signal reach a certain threshold.

  

  On the side of the LV, I use the API to call this sequence. I make sure that all channels and settings are defined as in the examples. However I get 307650 error that says "NEITHER VeriStand: Index was out of range." Must be non-negative and less than the size of the collection.

  ' Parameter name: index.

  Any suggestion to help here? THX. Code is attached.

  There are two problems here:

  1. The Stimulus profile editor is not indicating that there is an error with this sequence, although there is a. Note that the variable InitialTime is used in an expression, but is not declared as a parameter or a local variable.

  2. you get an error at runtime because of it, but it's not terribly useful (index out of range).

  You can fix this by adding a local variable of InitialTime to your sequence. I dropped the CAR 338386 about this bug.

  Once you do this, there is something extra, you will need to set in your VI which runs the sequence so he could get the results of the sequence properly. You use correctly the value of the sequence name to read the back of the sequence Variable. You use the Session name used during the deployment of the sequence. Which does not match the name sequence.

  To get the name of the sequence, use VI to get all the names sequence on your session profile of stimulus to get the array of names for all of the top level of the session sequences, then index on the first point, given that you only use a single sequence. Example below:

  

• Updated in real-time with text of exec system indicator

  I was wondering if anyone knows how to get LabVIEW to update an indicator of text with information from a command prompt in real time?  So, as if you ping IP show he ping and not just wait until the end to update it.  I try to have a batch file that processes the code displayed on screen so that the user can see that she is running and that it is not frozen.  When I ran the test originally she had a cmd window pop up and show that information was passing.  Since I opened the program with the exec system, it no longer displays anything so I thought that if she showed in a text indicator the problem could be solved.

  Thank you

  Help for the system Exec VI

  (Windows) To use a DOS command, insert cmd /c before the command.

  Then try this way the system Exec VI

  cmd /c 172.18.81.54>"C:\temp.txt ping.

  Change the IP address to your needs.

  The quotation marks around the path is necessary if you have spaces in the path of the file.

  Now when you do this you will get nothing back from the exit of stardard, because you have redirected it.

  The results should be read from the file.

• Using FTPClient on a real time with system Exec.vi

  How can I tell FTPClient.exe address target when I start this executable with system Exec.vi in Labview?  I don't want to reinvent the file FTP utility used by MAX with targets in real time. I want to run this executable to a labview support utility without using MAX to do.

  Is this possible?

  Danny

  Thanks for the info.  Your "bad mood" response "suggests" a response to my question.  However, the full answer to my original question is that it is not possible to use FTPClient.exe outside MAX.  It is therefore not possible to spend in the address target at run time if the FTPClient.exe runs external to MAX.  FileZilla is a good choice - there are also other FTP clients out there, but you pointed out a solid choice.  Thank you.

• Vision in real time with USB2?

  Hey guys,.

  I'm stuck to decide on a method of image acquisition.

  My project requires real-time imaging, but it is on a netbook, except that USB is out. Ethernet is only 100mbit so no gige.

  I tried a few Comsumer s level USB cameras that I slept here and all seem to have about a half second lag in all lighting conditions. Is there a solution for me?

  I tend to avoid the acquisition of vision with the USB.  I don't know what the limits are.  I know the that most consumer webcams are not enough good quality for machine vision.  There are a few industrial USB cameras, you might want to look at.

  Can you put a firewire card in your netbook?  It would probably be your best option, because there are a large number of firewire cameras and they are very easy to use.

• Display in real time with a delayed recording LV6.1

  Hi, I need help with LabView 6.1

  I have a hardware module FieldPoint where I read 8 channels for thermocouple. I want to display the value of the thermocouples in real time (or as close as I can manage) all saving the values in a CSV file at discrete time intervals (every 10 seconds). I am able to display the values in real-time, but the recorder real-time records, produce a lot too much data. I'm able to delay the recording interval, but in bulk then display in real time!

  The following example shows a method I've tried. The delay time in the loop of logging seems to delay the entire program. I also tried to use the loop of the logging of a sequence (using a simple delay of 'Wait') structure and a structure of matter (with a counter and only do the loop of logging real when the counter gets to 1). I tried to configure synchronous display without success.

  I'm having no luck and wonder if someone could point me in the right direction?

  Ah, the benefits of time.

  I think that I managed to create a solution for me using a different tact. Instead of using individual meters of delay, I used a "trigger time" approach as demonstrated in this thread;

  http://forums.NI.com/NI/board/message?board.ID=170&message.ID=286988&query.ID=6280650#M286988

  Currently, it is limited because it will allow only a delay of 59 seconds between the readings, but this should be relatively easy to solve. The solution works continuously update the display with a slight delay to help cope aging computers, and then the button "Log Data" is selected writing worksheet function is called second pushed together as selected. Quite a simple and elegant solution I think.

• Application errors of the RT with the PXI-4461 with Labview real-time 9.0.1, DAQmx 9.0.2

  HI -.

  I recently converted a PXI time system real OS (PXI-1042 q chassis, controller PXI-8187, DAQ, PXI-4461, DAQ, PXI-6259). I can write and run DAQmx applications in real time with the 6259 very well. Whenever I try to write a labview RT app to use the 4461, however, it will fail. Note that I can use two cards through MAX I tried switching card slots, just in case it was a problem. Both cards worked with labview, the PXI chassis was before Windows.

  Attached are pictures of the screw base demo I built to show the problem. Since I was a mistake (-200758) if I started from the raw strings, I tried to create a MAX task and use it. The task, but he complained of a buffer is too small. I explicitly put the buffer to work around this problem and still get the same error (-200608). I've also attached a screenshot of the software currently on the Max MAX RT PXI system is version 4.6.2 btw. (I installed the most/all this from DS1 Dev Suite 2010 version).

  Please let me know if I hurt something installed, versions if 4461 just don't play nice with the new BT or RT software, or if something is wrong. Thank you.

• Time zone / problems of the DST with XP mode VM in Windows 7

  Hi all.  I seem to have problems keeping straight time with my XP Mode VM under Win 7 Pro64.

  To the EAST, 2000 server is set to active TimeZones.  (Yes, it's old, we know!)
  My Win7 box is set to the active EAST of TimeZones.
  My computer XP mode virtual running under Win7 is set with DST enabled East.

  The server time is right.
  The time of Win7 is right.
  The XP VM is 1 hour late, and I can't change the time manually. (Jumps to 1 time in seconds)
  Files modified on the XP VM and stored on the server get time stamped 2 hours before the current time.

  New idea of what to check is greatly appreciated!  Thank you!

• BlackBerry Smartphones real time to sync with the calendar?

  I'm relatively new to Blackberry, my Motorola Q would make a synchronization of calendar in real time with my Outlook calendar on my pc at home. When I added an appointment in the Q, the Outlook calendar could be updated shortly, is it possible to do it with the curve 8330? So I don't have to come all day from home and plug it in. Thank you

  Hi and welcome to the forums,

  Wireless calendar synchronization is available only for BES users at this point, so if you or your business to work with a Blackberry Enterprise / Professional Server, then you will have sync wireless real-time.

  However, if you use the BIS service, you can only synchronize with Blackberry Desktop Manager with your PC.

• Conspire in real-time

  Hello

  I'm working on a project of tension. I have read the data using the OPC. My variable is double wall to an address of mutual FUNDS. I want to plot these data to 10ms resolution. Is this possible?

  I have download a code sample, I tried to solve this problem. but is is not accurate and does not.

  You have an idea to plot the data in real time with a resolution of 10 ms?

  Hi beginner,

  you really need to redraw your project!

  (1) not the OPC data source really provides new data with sampling frequencies of > 100 Hz?

  (2) do you really need to draw the new data with a frequency of 100 Hz? You can't look at the graph that fast!

  If 1) applies: make a separate loop to collect data at the necessary pace in a registry to offset (or any other method to store the data). If 1) does not apply: lower the rate to which you are trying to read new data!

  (2) applies (no alternative): update your table with a rate of (say) 5 Hz. It's always fast enough when your field visualization and a lot less CPU consuming.

  You need to separate the task of gathering data from the task of their display!

  Your last question:

  Any multitasking (standard) OS will involve a big Jig in your loop times. With a RT - OS this jitter is much smaller, but still different from zero. See the plug...

• Structure of the timed real-time event loop does not work

  I'm a new user for LabVIEW. And I've encountered a problem that frastre really me! Hope someone can help out me. Thanks in advance!

  I just want to use the structure of the event under timed loop, which is important in my extrmely design.

  However, this works very well in my computer (without connecting to the FPGA).

  Once I connect it to the FPGA, then I can still run but there is no response!

  My file is attached. Please someone help me!

  Looking forward to your answers!

  The FPGA runs headless. Structures of the event won't work. What you need to do is to have an application on your host computer when the user presses a button, changes a value, etc.. This event should send a message via TCP/IP for code that runs in real-time environment. Then the real time environment should attribute to the desired value a control on the FPGA.

  As a general rule, programming real-time with FPGA has several layers.

  (1) host-> handles interactions with the user code and communicates the code in real-time via TCP, UDP, etc.. Displays the user sent by RT controller data.

  (2) code in real-time-> tracks headlessly. Manages host code messages, processes the data of FPGA, communicates with FPGA much as the host code communicates with the code in real-time

  (3) FPGA-> no acquistion and passes through PEP in the RT

  The first thing you need to do is to understand the architecture and how all these pieces of the puzzle work together before you throw things down on a diagram.

• Video editing in real-time, is it possible?

  Hey all, first of all thank you for reading this post.

  I would like to know if it is possible to apply some effects (especially twixtor, some warp stabilizer, color correction) and see the result (perhaps at lower resolution, resolution 1/2, 1/4), without rendering, but the liquid (to check the image goes accordingly with audio, to see the speed change is control with twixtor, etc...)

  I have a laptop that is supposed to be powerful: i7-4800mq, 16 GB of RAM, GTX765M, and (perhaps it s the reason why I Don t see the expected result) a hard drive 7200 RPM (SATA 3 GB/s, with 64 GB SSD mSATA capture)

  I use the video recorded mainly a gopro 3 black and first pro cs6, sequelae. 1080, 60 frames per second.

  I want to change my computer because I have to do a lot of editing of short videos, a lot of twixtor and can´t waiting for renderize whenever I change something and the bar changes from green/yellow to red.

  I would like to know:

  -If it is normal, with my computer

  -If you intend to buy a computer, instead of asking which component you should buy part of (of course you can), what you think of these two:

  option 1:

  I7 - 4790 K 4.0 Ghz

  MSI GeForce GTX 980 Twin Frozr OC 4 GB GDDR5 V

  Motherboard: MSI Z97 Gaming ACK 9

  Hard drive:

  • Seagate Barracuda 7200.14 3 TB SATA3 64 MB
  • Samsung 840 Evo series of SSD SATA3 500 GB (250 GB x 2 In raid 0)

  Kingston HyperX DDR3 2400 16GB PC3 - 19200 2x8GB CL11 Savage

  
  

  Price: approximately 2100 euros

  option 2:

  4790 K I7

  2 x GTX760 2 GB of GDDR5 memory

  Motherboard: GA-Z97X-SLI

  Hard drive:

  - 2 x HDD 1 TB 7200 RPM Seagate ST1000DM003
  

  -2 x SSD 120 GB Kingston V300
  

  16GB DDR3 1600 MHz (2x8GB) HyperX blue Fury series HX316C10FK2/16

  Price: about 1600 euro

  I know that I can use proxyes, but I think proxyes with less resolution gives problems with the stabilizer of warp and with less fps gives problems with twixtor.

  Don't you think that I'll be able to do the video editing in real-time with these computers? Thank you very much!

  GoPro black 3 is very slow on CS6. Twixtor is poorly threaded and does not support CUDA acceleration.

  Re option 1:

  • The 980 is way exaggerated, a 760 is more than enough.
  • 16 GB memory isn't enough, you want 32 GB.
  • Forget the EVO. It's far too slow with the Scriptures. Get a 850 Pro.
  • Get a few more HARD and SSD drive to improve disk i/o.

  Re option 2:

  • A single video card is supported under CS6. Go on the other.
  • 16 GB memory isn't enough, you want 32 GB.
  • a single 120 GB SSD for media cache and previews is very low. Better to use 256 GB Samsung 850 Pro.

  With GoPro material and even with the improvements suggested (more memory, better disk i/o) that you will still experience slowness, jerks, unstable behaviour, because of the quad core CPU.

• Issues of time with 5 c

  MY wife just brought a second hand 5 c 16 GB phone cash converters. Everything works fine except the date and time. It will not update and the clock does not move. All location-based services are switch on and I tried to set it manually. When I do work for a few minutes and then stops. The phone would update latest version before we he restored from a previous phones settings. Apple think it might be a hardware problem and suggest that to consider return.  Until I do, anyone met this before.

• Run a VI in real-time without a delay

  Hello

  I want to communicate in real time with a sound level meter via a serial port. I have already created my program, but I still have a 3 second delay, maybe it's not important but I have to remove to my request.

  Is it possible to completely remove the delay?

  Just for the record, my Vi contains two local variables, could that be the reason? Or perhaps because only a certain port timeout series?

  If you need to see the program, just tell me.

  Thanks in advance for your help.
