Put the data of the set point in a waveform graph

Hello

In a graph of measure, which is the result of a waveform, I would add data of the set point as well. How can I add this data to set for the chart value?

In a control loop system, the output is controlled by a labview program. I would like to see the point of this system as well as in the graph, these thresholds are changed at random times, so I don't know how to create a waveform of these data. Should I create a waveform of the setpoint, or y at - it another option to show the set value in the chart?

See you soon,.

That can make it much more difficult.

At one point an array of 1000 points need to be assembled (obviously). How do depends greatly on your structure. Synchronize the time of the two signals can be very difficult. It would be easy if the set value only changed once a cycle of 1000 point.

You may want to read the SP as an analog input, so you get 2 samples of the material here. In this way the two will always be synchronized. But I'm done alleady assumption, like this, the signal is an analog input (and the target value of one analogue output). What equipment do you use?

I think always need you a loop to get data and a loop to set the SP. The two loops will be more parallel execution GLSL and synchroniseent. The trick is to synchronize, or for the deterministic timestamps in two loops. If you can make that happen, you 80% there. You could do loops timed loops (using the same clock). Then you get the timestamps in two loops. The MS loop has the queue changes, pushing the value and time. Then the loop of data can use values and hours to create examples of sp 1000.

  • Having bad to write the set Point to clip MFC

    I've already written a Subvi for reading and parsing the output of a scientific MFC of clamp (16 series), which works very well, however, I have some difficulty in sending a set-point in the MFC. I have attached a Subvi test as I write. All of the com parameters are matched to the CMF as well (19200 baud, 8 bits of data, no parity, 1 stop bit, no flow control). After setting the appropriate resources channel, I enter the following in the field of the buffer:

    \r\r\r\r\r\r\r32000\r

    which I believe must send the deposit to the MFC, but I am seeing no response. When I entered the same string in the VISA test panel in MAX, it works however. Anyone has an idea on what I'm doing wrong? Please also let me know if there is any additional information I could provide that would be useful. Thank you.

    You send the characters '-' and 'r', not a carriage return.

    Place the command string buffer writing '-' display of Codes in order to send '-' Codes correctly. It's a simple right click.

  • What is the setting point in v2 profile us Web Coated Swop of gain?

    Hey guys,.

    This may seem a bit of a n00b question, but I really can't find that info all what I Googled it.

    What is the point of setting default in v2 profile us Web Coated SWOP of gain?

    Let me explain my dilemma:

    My printer told me to use the US Web Coated SWOP v2 this profile for a catalog that we will print. 4/4 on gloss 100 # book stock. However, I have used this profile in the past and the prints came out darker as I expected. I don't have a printer of high enough quality to be able to test this in-house, but I am sure that my monitor is too bright or set a contrast too high level. They told me that their standard mast is approximately 10-15%

    I assumed the SWOP v2 profile 20% fattening as seems to be the default for most of the other color settings, but I've never known with certainty. I am trying to decide if I need to use a custom profile with a highest point gain setting.

    Thanks for any help!

    Kenzier

    Hello Kenzier,

    the U.S. Web Coated SWOP ICC profile contains a reproduction of the tones (CRT) curve

    which can only be described accurately by Dot Gain or Gamma.

    For entry into the color settings > Gray we can proceed as follows:

    Color settings > Gray > grey load > (click on) USWebCoatedSWOP.icc > save gray

    This saves a 'black-ink-profile' with a similar name, which replaces the Dot Gain

    or Gamma settings.

    This profile can be interpreted by the ICC profile Inspector (free) program:

    Here we have kTRC (shades of black ink reproduction curve), the red line.

    With the diagonal black auxiliary, it reads 20% efficient fattening,

    the blue line.

    The printer should tell you a representative profile (a good approximation)

    for its actual process.

  • The set point is not not active?

    Hello

    How can I do the update to transmit an element?

    Let's say I have 3 fields on the page and focus on the first field. When I press tab, the focus must ignore the next (second) and lands of a 3rd.
    The second field (the one that must be passed) is a field of text (disabled, State of stops), read-only Condition Type and it is a static text with Substitutions of State of Session. In other words, it cannot be changed and cannot receive user input. It just shows the value it gets shape data...

    Hey guys, I think it was easy to do in older versions of first, but I'm not sure.  In the export window, I want to put the final point of the media that I export manually.  All I can use is the small triangle on the right, but that gives me no details.  Curiously, I can manually enter the starting point in time code, but not the end point (it is unclickable).

    Thoughts?

  • Eurotherm 2404% manual power set point

    I'm using the LabView ET24xx driver. It works fine if I want to set and control in automated mode. I'm looking for the ability to create a vi that allows me to switch to manual mode (able to do that) and adjust the set value (can't do it). The set point in Manual Mode is generally the percentage of power. I would like to be able to establish to anything other than 0% or 100%, however when I use the driver it does not appear as a method of manipulation of this. I know I'm missing something, and any help would be greatly appreciated.

    Thank you

    Tennessee Paul

    Thank you, Robert. After a lot of research I found the solution:

    Use the VI: ET24XX configure OP key parameters 2. VI

    key point in the use of this VI. The power (or control) setting labeled power output target is in tenths. A value of 5 = 50%. A value of 0.5 = 5%. With this VI no value greater than 10 will work. The VI will timeout on the "Write" command, if the value is greater than 10. I don't know why this VI was established in this way. Remove the output target x 10 serving power and wiring of the power output target control directly in the table of generation within the VI allows a more intuitive entry of power, until we realize the value of the power output target is %.

  • 3.6 spot healing Lightroom crashes, not showing do not set points

    I waited months to update to 3.6 because I finally got Lightroom works fine on my machine. Earlier versions would hang on the spot on the sharp heal tool I have to close it using the Task Manager. The problem comes when I edited a file in an external editor and I'm working on the tif file that was imported into Lightroom. The just spot Healing Brush tool will not work. This continues to happen even when I close Lightroom and return to the file later. This me really bums as it overwrites just my workflow!

    I also have a new problem. It could be that I touched something somewhere to cause the following behavior. When I work on an image with the adjustment brush, the set point disappears. It appears so if I want to change the brush settings the point are there not to click on an active brand, so I can adjust the settings again. It started just because I upgraded to 3.6. I think I was using 3.4 before and I've never had this problem.

    Thank you in advance for any help you can provide.

    There is a bug in Windows that will cause LR to hang when you move the circle 'source' (at least some) JPEG files. It can so happen with TIFF. Lightroom will lock tight for a period of time in seconds to several minutes.

    To work around the problem, you can set the processor affinity for Lightroom to use only a single core. Under windows, bring up the Windows Task Manager, go to the process tab, right-click on the process of Lightroom and choose Set Affinity... Disable everything except a processor.

    This bug will be fixed in LR 4, of course.

  • I've set up the virtual machine in win 7 Ultimate and put some data. Now when I try to connect it asks password and does not accept any password.

    Default password Machine virtual XP Mode

    I've set up the virtual machine in win 7 Ultimate and put some data. Now when I try to connect it asks password and does not accept any password. Please giveme the default password

    If you're talking about XP Mode the default password is XPMUser.  In general you can not use Windows without a password in Windows Virtual PC that you can with Virtual PC 2007 and before.  XPMUser is used only with the XP Mode virtual machine.  All other virtual machines requires a user created password.  If you have changed the password in XP Mode and forgotten, then you have to start over.

    Windows Virtual PC is based on virtual server rather than VPC and all virtual machines need a password.  If necessary, uninstall the integration features, start the virtual machine and create a password for the admin user.  Restart the virtual machine, and then reinstall the integration features.  You will not be able to access a virtual machine created by the user that has no password, while the integration features are installed.  Once you have everything right, that a virtual machine will not be asked a password if you are the admin user in Windows 7.
