CGRA Clones run in series - sometimes

Similar Questions

• reading and writing series sometimes works, sometimes expires

  I use the series on the VIs VISA to acquire data through an instrument.  After you have configured the port, I have send the instrument the order "AZK" followed of a newline (string hex "2A 61 7A6B 0D").  This brings the instrument to trasmit data.  When I do this in Hyperterminal with the same port settings, it works every time when I repeat the command as quickly as I can without any problem.  When I start my VI in LabVIEW, sometimes it works and sometimes it isn't (work maybe 25% of the time).  When it works, the data are displayed in an indicator very quickly.  When it doesn't work, I get a timeout error (10 seconds).

  I think the data string is ~ 330 bytes; Since I'm troubleshooting, I have it reduced to 20 bytes in order to ensure that the reading series is not waiting for more of bytes.  I also tried to extend the timeout, but it doesn't help.  Thinking this was maybe timing, sequence, or buffer related, I also tried to write and read in frames separated from one frame of the sequence and also tried an initial framework with clear VISA to clear the buffers before writing and reading, but none of this has helped.

  Any ideas why this might work a while but not others?

  I have attached a VI that I use to try to get this working.  (Note some data, the analysis of operations, as well as the VISA read a previous VI, but they have not been configured for this instrument of entry again and only the input string of reading indicator is significant at this time).

  If I can't get this to work, my rescue is rule automatically the instrument on trasmit on a certain frequency (like 1 sec) and acquire these data.  I was able to do this successfully with another device series.  But I wanted to be able to have LabVIEW to control the timing of transmission data as this unit has this capability.

  Thanks for any help.

  You can try adding a delay between characters like Hyperterminal does.

  And please don't say that you use the continuous run button. That would be a mistake.

• How to automatically run an order of series

  Hello

  I'm brand new on Labiew. I did a vi as attaché to the reader one shoot-syringe and rotary valve, and it worked fine. what it does is send command whenever I click on the button "pump" or "valve".

  But now I want to run a series of commands automatically, for example, #1 à #2 valve, #3, and #4 to pump, pump pump of order total orders etc. will be around 10. I wonder what is the best way to carry it out.

  Thank you very much

  Make a (a typedef) cluster that contains for example information on the time and the type of order (I assumed you don't want different time controls)

  Make an array of these "clusters of command" (or a queue, find out more about QMH) and stream to a state machine that emits orders at the right time.

  If you are new to any of these concepts, learn about the documentation free before you start:

  https://www.NI.com/getting-started/LabVIEW-Basics/

  Moreover, you don't need the outside while loop. Instead, perform the shutdown affects a case in the structure of your event and the stop wire terminal to be true in the case of stop button.

• Connecting series of camera link vi - simple program does not

  I have a program very simple, attached here.

  The command, 'PAG' that is sent via IMAW series write must return a bunch of text describing the parameters of the camera. Every time that it runs, the series read times out.

  I looked through several examples showing how to use the functions IMAQ series write and read series, including several discussions here, but I have yet to find anything to indicate where I have gone wrong.

  Please take a look and tell me what you think. Thanks in advance.

  Installation program:

  Windows 7

  LabVIEW 2011

  Acquisition card NI PCIe-1427

  DALSA 1 M 30 camera, Camera Link

  Hello

  Did you check the syntax of the command, you must send with your digital camera?

  Each supplier of the camera has its own syntax.

  Sometimes, you just add a newline at the end of your chain command.

  

  Hope this helps

• HP Pavilion 6 computer running slow

  Hi guys

  My laptop Pavilion dv6 HP with Windows 7 home premium o/s started running really slow sometimes. I run C Cleaner regularly and drive C is only half full. What happens is that when I type if I pause for a second or two and then re - start typing the cursor stops moving and then he jumps in life and all the typing is displayed. Then it wokrs OK for awhile until I stop again, and then he may or may not have the delay. It's really frustrating because you don't know what he's doing or when he's going to do. I do a lot of photo editing and the same thing is happening and is frustrating evenmore. Can someone suggest what I can do to fix the problem

  Thank you

  Hi David

  I had the assistance of a computer store. Not only the computer that is running pecularly but I got a message that the wireless network could not be found. It turns out that the problems were related and that there are bad sectors of hard disk which meant wireless has stopped working. I now have a new hard drive and all problems are gone. They have DVRs, been able to clone the old drive hard so that all my files are always available to me. Anyway thanks for your suggestions. I think that you know the problem was with the hard drive and you were right.

• LabVIEW FPGA SPI accident - SPI OR IP address for example - R series OR

  Hello

  I am trying to run the series R - sample project NI SPI FPGA Simulation.lvproj that comes with the SPI IP OR on a real FlexRIO FPGA SMU-7976R target with an attached digital adaptation NI 6581 B Module. The example is for a PCIe-7841R but I wore during my target FPGA, follow these steps and made additional changes to try to make it work with my set-up. I learned that FlexRIO FAMs CLIPs do not work with nodes in office had so I know I can't simulate the project originally planned so I will try to use FPGA to e/s node host side (open FPGA vi reference) to implement the actual hardware.

  My first question concerns my configuration of the adapter module e/s and selection. I added the IO Module (NI 6581 B: NI 6581 B channel) for my project and selected the channels as shown in the table below. I have a real physical hardware connection as described below using two NI SHC68-C68-D4 cables and a break-out Board.

  

  I changed the names as well:

  

  I selected these DIO channels because I wanted the DDCA connector to be the master and the DDCB connector to be the slave. In addition, in this CLIP every eight channels of i/o has a write enable signal. I have not used the Port configuration because I needed 4 available DIO channels and I saw DIO0-3. Is my logic of selection of channel vs correct Port here?

  Following the same strategy that examples FlexRIO/NI6581B, I changed the FPGA.vi to include initialization outside of timed loops:

  

  And in the Host.vi I have a node reference FPGA and wired loops of feedback accordingly:

  

  When I compile the FPGA and try to run Host.vi LabVIEW inevitably crashes with Crash Reporter below and must restart:

  

  Does anyone know what I'm doing wrong here? My guess is that it has something to do with the CLIP/IOModule. Any help is appreciated.

  Thank you

  Scott

  Hi Scott,.

  I suspect that the problem might be related to the fact that your node open FPGA VI reference is in the while loop and trying to open a new FPGA reference at each iteration.
  If you move outside of the while loop, it does not solve the crash?

  On channel vs port question, your logic seems reasonable to me, but I recommend to try it since this feature could depend on device.

• Prerequisites for reentrant SubVIs to run in parallel

  Hello!

  In my VI, two clones préallouées of a Subvi, I thought I would go in a separate thread of each. Just this sub - VI contains a reference to a double and it increments. The two clones ran in parallel, but not in separate threads. For comparison, I did a Subvi, which does not have a reference - these clones run each in own thread.

  I noticed this watching the CPU usage: in the first case, has been used as a single core in the second respectively two sons were used.

  (1) I wonder what are the prerequisites for a Subvi to run effectively not only in parallel, but in fact in separate threads?

  (2) is there a way to discover during compilation which (Tufts) parts of a VI run in parallel, and SubVIs get making their own thread of execution?

  For reference: the execution is slow. If I understand correctly, the GUI is running in its own thread, so no interfering only not with the SubVIs that multiply references. I think that there is also no locking a reference readings and writings to a reference should be very fast. Is this correct? If so, why is this slow running?

  Thanks for your replies

  (The test computer has a Quad-Core with Hyperthreading, using LabVIEW 2012SP1)

  One thing I know is if you have any manipulation of the UI elements.

  In the case you use a reference to a UI element user and properbly using the property node to insert data.
  This limits LabVIEW for your sub vi of in the UI thread.

  If you have transferred the values on the queue to a vi that manages all the user interface controls, then only that vi will be in the UI thread.

• How to navigate in a running block diagram which is used in a high school?

  I have a Subvi called Servo.vi which is called several times (cloned) in my application. The façade of a selected Servo.vi is placed in a secondary school in my Main.vi so that Servo.vi can be controlled from the front panel. When the Main.vi is running, if I use the block diagram of Main.vi to access a clone running of the Servo.vi and double click it, LabView 2010 navigates me to the secondary running at Main.vi, instead of a separate Panel. But I am not able to show the block diagram of the cloned since high school running in Main.vi Servo.vi.

• Autorun Clone Popup

  Sorry to ask this question because yesterday I thought I got it running but only for a single process.  If I click on the button "Run B", it should open B.vi:1 (clone), click on it again it will open to B.vi:2 (clone), for B.vi:3 (clone), etc...  All 3 of them should run automatically at the same time, but the best I can do is a single process execution where LV must wait for the first clone to complete execution before I can run the second clone.  Which is really defeat the purpose of parallelism.

  This method allows me to open several clones but them does not at the same time:

  
  Although this method defeats the purpose of concurrency:

  

  So my question is how do I get all B.vi (Clones) running at the same time, a simple click of a button?

  Please note that the example environment TCP which came with labview works only if you do not want popup.  I want to create several popups in VI even so that my end users can monitor what is happening in the process.  So I have a VI to tweak if I need to upgrate somethings.

  The clone that you launch a 'B' vi stops running when you close the reference.  Run it with active debugging and execution of follow-up allowed to see for yourself.

  You must wait for the reference until vi 'A' is done.  If you expect vi B be running after vi one stops and goes idle, setting auto-dispose to true and do not close the reference.
