• Strange problem with analog output PCI 6251 and BNC-2110

  I'm controlling current source of third parties using the connectors of analog output on my card PCI 6251 and BNC-2110.

  The current source needs an input signal of 0.1V. I tested it using a battery, the potentiometer and the voltmeter, and by manually adjusting the voltage of power current works - current output with control voltage scales according to the specifications and is relatively stable.

  The data acquisition card works too - when I connect a voltmeter to the AO0 AO1, the measured voltage corresponds to the target with great precision value.

  But when I connect the current source of third AO0 AO1 data acquisition card, the measured output voltage drops and fluctuates. This applies to both channels of the AO.

  I wonder what is the problem here. I suspect it could be a matter of the grounding - the current analog control of the source is an entry with two floating terminals differential. I tried to return the switches FS/GS on the BNC-2110, but that makes no difference.

  Anyone knows similar behavior? Does anyone have any suggestions?

  
  

• Output USB amps and the voltage on the Satellite A100

  Help, please. I have a device that recharges its battery via the usb port. It only came with a car charger which has an output of 5 v 1. 0a - what is the output voltage and amps for my Satellite A100 usb port?

  Hello

  Generally, the USB ports provide 500mA.
  USB voltage values are know not to me but to my knowledge all the USB ports must supports USB standards.
  So if you are using a device that supports the simple USB 2.0 standards you should be able to recharge your battery

• To input analog shutdown when the analog output is completed and synchronization

  Hello

  I'm trying to get my LabVIEW program to send analog output to a computer and read acceleration using the cDAQ-9184. Chassis output that I use is the NI 9263 and the chassis of entry is the NI 9234. I generate a signal of white noise using LabVIEW Express signal generator.

  The first problem I have is the synchronization. I had an old VI that has begun to measure the acceleration just about a second after the entry has been given to the machine. I used the LabVIEW tutorial on how to sync the analog input and output, only to discover that it does not work with two different hunts. Then I found another tutorial that shows how to synchronize different frames between them.

  The second problem is the cessation of the LabVIEW program. What I want to do is to generate the signal and then simultaneously send and read the input and output analog, respectively. It is because I don't want a phase difference or any shorter signal for a direct comparison. But as soon as the signal is sent to the machine, I want the entry to stop analog playback and then then the LabVIEW program must stop. I want to be able to choose any length of signal to be generated and stop as soon as the entire duration of the signal has been sent to the machine.

  I tried 'DAQmx stop', "DAQmx Timer" and 'DAQmx's task made?' and none of them have worked for me. It is also my first time on a forum posting, so I hope I gave enough information. I enclose my VI as well. The VI shows I read an entry for the analog input voltage, but I am only using this to try to get to the work programme.

  I'd appreciate any help I could get.

  Thanks in advance

  Hi Peter,.

  I have some recommendations for you that I think you will get closer to your solution. First of all, I assumed you meant that you had 1 chassis (cDAQ-9184) who had two modules in it (NOR-9263 and NOR-9234). My next steps are based on this assumption, so if it's wrong, please let me know.

  For your first question about the synchronization, the code you provided is very close to what you need. You need to do, however, implement architecture master/slave for startup tasks DAQmx functions. To do this, you can add another frame to the flat sequence structure and put the master start task (input voltage) after the start slave (output voltage) task.

  To manage your second question and that the program ends at the point where you, the first step is to get rid of all the logic that you use with the local variable of length of time. Rather than use this logic, just wire the node "task performed?" of "is task performed?" operate to stop the loop. This will cause your loop to stop as soon as the signal is sent to the machine.

  I have some other recommendations for you that will increase the performance of your program:

  (1) rather than writing on file inside the last loop, you can use the DAQmx Configure Logging (PDM) .vi. You will place this VI between DAQmx Timing.vi and DAQmx Start Task.vi to the task of the analog input voltage.

  (2) after the last while loop, you want to stop the task and analog outputs as well with another DAQmx stop Task.vi.

  (3) rather than using a local variable for the entrance of displacement and wiring it in the DAQmx Write.vi, you can wire directly from the output waveform of the wave to build function node.

  That should help you get started in the synchronization of these tasks.

• Output of Pick and Sample & Hold DAQ

  Hello

  The VI I must do the following:

  1. Generate low frequency (~ 1 Hz) saw tooth (DAQ AO0) value
  2. Entry of reading (DAQ AI0), which depends on generated value (for simplicity I just connected AO0 with AI0)
  3. When some condition occur, immediately stop generating sawtooth and maintain the last value on AO0

  For simplicity, "certain conditions" is realized as transition 20th the sawtooth on the threshold value.

  The interaction between 'Génération' and 'Acquisition' loops is carried out with the help of the local variable ""Stop generation loop "."

  This Setup works perfectly except the following:

  1. When stops in 'generation loop' , value of production data acquisition is not equal to the threshold value (as it is supposed to be)
  2. The DAQ output value does not depend on threshold... threshold value is set, the output is about 2.2V (ordered on oscilloscope)

  Any suggestions welcome

  What could be the reason for this inaccuracy?

  You have a race condition with the local variable when the variable is read before the release gets its new value.  That's why the loop iterates again.  Thus, you should use a flat Structure of the sequence to force the local variable playback after you the value of production.

  

• Is it possible to output a string and digital front without the border around it?

  I know that I can change the border around a string or a digital output to the screen using modern or classic, but is possible to output and the numeric values to the front channels without the border around it? This is particularly useful for panels to front I want to print.

  You are to halfway it using the conventional versions. The next step is to get out of your paint tool and paint the color of the transparent border.

• 2D Array output confusion - arrays and loops

  Hello

  I am writing a program for a measure 3-terminal of a FET.

  I use 2 power supplies: for every increase of grid voltage Vg, I'm doing a drain voltage Vd Sweep and save the Id and Vd.

  The attached code, you'll see a Subvi, called "I.V. 2 terminals", which returns a table of voltage Drain (1 d) and a table current Drain (1 d).

  But because the output of the Subvi is in a loop (For increment Vg), the end result is a 2D array.

  Whenever a table is leaving a loop it acquires a dimension.

  So ultimately I don't know what are the clues. How can I prevent the table to have a dimension of their out of the loop For?

  I would like to see the output of the Subvi to go straight out of the loop, intact.

  I have attached the Subvi as well, but I don't think that you will need.

  Thank you! I'm still very new to LabVIEW and I really appreciate your help.

• Synchronization of AO and output counter, arming and triggering the sequence of events

  Hi all

  I'm trying to synchronize a counter (used as a digital pulse) and analogue of a custom waveform output read from the file on a USB-6211. The goal is to always have these running until I hit 'STOP' and to be able to change the position of the pulse relative to each other. I created a VI by combining and modifying the Cont.Gen.Wfm.Int - Clk.Non - Regen.VI and the Continous.VI Gen dig Pulse Train and I'm now able to produce the two signals to the desired frequency, but I can't seem to get the "Initial period" to work correctly. The values that I come home do not seem to match what is happening LeRiz, and the spacing seems to vary from run to run (within each series is constant). In a previous post, Alfred has suggested:

  "Trigger counter outputs out of the trigger to start AO and adjusting the setting 'Initial period' should give you what you are looking for."  Don't forget to start the tasks of meter in the software before the tasks of the AO (if they are armed and ready to go before the start AO is sent). »

  (link here)

  I tried to use the controls and the propertynodes (perhaps incorrectly), but it doesn't seem to make a difference.

  I think what happens is that my arms and firing sequence is not done correctly. I read on as much information as I could about the outbreak and armament, but I don't know that I understand correctly. Most of the examples I found using an external trigger or perform analog input tasks finished. Does anyone have a suggestion on how to start my two tasks in the proper order? Is something else is wrong here?

  Thank you

  Gabe

  P.S. I have attached the VI and a sample waveform read.

  Hi Gabe,

  This is a cleaned of the VI version that should work (you need not adjust the initial deadline on the right fly?).  Instead of reading a file, I made just a simple square wave of 50% to be used for the test.

  Best regards

• Need a sample RH11 Webhelp output with categories and browse sequences...

  I am looking to test a plugin (of sorts) with any HR 11 Webhelp output that uses categories and browse the sequences. A Webhelp output from the sample project Salesbuilder 2 would suffice. I won't buy another version of HR for a trial.

• Automation in output of sources and handaling file

  Hello, since the release of version 2014 these became a problem very grid for me:

  I can't find some way to do simple and complicated automatic processes for the control of several files.

  Am I missing something?

  Thank you.

  I have found a workaround to change some predefined settings:

  Let's say I have 50 sources with 5 outputs each: Crop1, crop 2, harvest 3, Crop4, harvest 5.

  1. make all desired presets.

  2. all included in a group, except one, for example exclude "of cultures 1" of the group.

  3. import all Sources I need.

  4. automatically SOUL gives a pre-defined parameters by default, on change of some sources it in 'Cultures 1' "Preset".

  5. then, so that all sources always selected to group and double-click it, these will add the rest of the presets 'Crop 2' to "Crop 5".

  When I want to change a certain "Preset" I need to change the preset in that group and redo these everywhere.

  This is the best I've found.

  Always to research on the naming convention issue but nothing yet.

• The HTML - output folder Option and the path of file name change question

  In the HTML Options to file and output file name I was wondering if I can change the name of the .chm automatically listed when I click on properties?

  For example, when I click on properties for ABC_v456, which is a SSL in the project ABC123, I see "C:\Projects\ABC_v123\!" SSL!\Help_v456\ABC123.chm' in the output folder and file name field.  I would rename ABC123.chm in ABC456.chm for the love of light. When I compile it will then create a file .chm by ABC456.chm name rather than the name of the ABC123.chm file? I would have then two SSL in the HTML project called Help_v123 and Help_v456each and their respective .chm would be within each folder.  I speak of the sense or is this clarification requiring gibberish on my part? I use Robohelp HTML v7.

  Hi karima

  You should be able to freely appoint the CHM everything that makes sense for you in the field.

  I remember that too, you are perhaps involved in the development of CSH. If the name of the file could play an important role in that. But even after you generate the help, you should be able to rename it if you wish.

  See you soon... Rick
