• Active control of vibration of the flexible mono-faisceau

  Hi, im working on the active control of vibration of the unique flexible built-in beam, and I need to design that helps me control the beam active & passive.

  two experiences of control a robot with unique flexible bond. The link is operated in bending by two piezoelectric glued to the surface, and the local curvature is measured by piezoelectric sensors, forming a pair of sensors/actuators colocated. In both experiments, the articulation describes the same polynomial trajectory that excites the Eigen modes of vibration of the binding. In the first experiment anti-vibration with piezoelectric actuators are off, and we can observe a very long time to maneuver as link oscillations themselves naturally. In the second experiment anti-vibration are lit, and a significant reduction in the time settling is reached

  Cabo,

  So, it looks like part of what you are trying to do is the generation control system a PID in LabVIEW. Fortunately, LabVIEW includes a number of useful resources for the PID:

  Here is one of our books (with the tutorial files) whites, discussing implementations in LabVIEW PID: http://www.ni.com/white-paper/6440/en/

  Here is another tutorial on implementing PID using the PID.vi: http://www.ni.com/pdf/labview/us/implement-a-pid-control-system.pdf

  Here is the help documentation for PID.vi himself: http://zone.ni.com/reference/en-XX/help/371361L-01/lvpid/pid_vi/

  Finally, example finder LabVIEW has a large number of projects example PID you can experiment with. Just go to help > find examples, then find "PID" and select any project matches your planned the best implementation.

• Is there a way to control the fonts used by a remote façade displayed in a browser?

  When you use a web browser (on a system with only the TEN LabVIEW installed) to monitor a remote façade commissioned from a cRIO is a way to control which fonts are used by the browser when it displays the Panel?  In the case of a stand-alone executable, I know that you can include definitions of fonts associated with the executable 'appfont' and 'FPfont' in the INI file to control the fonts used by the executable. Is there something similar that can be done with a front panel running in a browser window?  Or do I go through the VI and explicitly define a non-generic font specific for each control and indicator that is displayed?

  What is the size of fonts in windows on the PC?  It has 125%?

• Control PCLK when using the PXI-6534 in e/s mode

  I use ports 0 & 1 on the PXI-6534 in e/s model mode and also use output control in the mode of e/s to unstrobed for simple.  Users manual says in the mode of e/s model the PCLK control is not used, but the mode of e/s model seems to put down (or maybe he defines as an entry).  This a problem for me because I expect to PCLK to stay a high return which I set earlier.  Does anyone know how to set up the PXI-6534 in e/s model mode so that this does not affect PCLK... He's going to stay high?

  Thank you.

  Jim

  Hi Jim,.

  According to page 2 and 3 of the PXI-6534 user manual, if you configure a group to perform i/o, associated for this group synchronization control lines are not available in the form of additional data lines. The knowledge base, here, explains this limitation for the PXI-6534. In summary, port 4 is reserved once you are in e/s handshaking mode or a model and cannot be used as data lines additional unstrobed.

• Can I know how to control the robot using LabVIEW? My PLC is Omron CJ1M-CPU11-ETN21.

  Hello

  I am new to LabVIEW, and I need help with the configuration between LabVIEW and the controller. My PLC is Omron CJ1M-CPU11-ETN21. I have the DSC Module and I have an OPC server as well. I create tags or even used the shared variables to try to write to the output of the PLC, but it does not work. The configuration for the ethernet Powerline had done, and I can control the PLC using CX-program via the Ethernet module. May I know what are the problems?

• Active control is indicated

  When running my application, the active control in the UI has a black outline that I find unattractive.  Is there a way to make disappear?

  Thank you.

  As much as I know there is no way to disable the highlighting in the active control. However, if the command has a lable, the highest point is around the lable instead of the control itself, it also means that if you move the lable off area of the visible screen (for example with a value of 5000 left label) the nail will not appear on the Panel.

• Question about activating windows and media used for installation

  Intel Visual BIOS 2 my computer on board DZ87KLT - 75 K (Firmware updated) can not detect the optical drive as boot EFI device. So I made a bootable USB flash drive to my system OEM Windows 7 Pro x 64 DVD manufacturer who (USB flash drive) my system detect successfully as efi boot device. My question is if I do a windows 7 clean install with EFI enabled using the flash drive on the same computer that runs this window for the last 9 months, there will be an activation problem to not use the DVD?

  The problem is that your key is already used. He'll have to re - install Windows by using the same key (as long as it's the same motherboard and not a replacement) phone activation.

• Satellite A30: strange loud noise from speaker & headphone

  Hi guys,.

  I bought this laptop some time ago (3-4 months). Don't worked fine, no problems at all. Used VOIP (Skype), etc.

  Then I started having strange noises of frying (speaker and headphone).

  And now - after a month or two, I started having this problem - I can not record voices.
  This laptop isn't microphone with microphone. tested the microphone with another laptop, it works fine.

  Reinstall the driver did not help. :(

  Anyone any idea?

  THX!

  * @ matt13 *.
  If the technicians have tested this laptop and didn t find any abnormality of speaker then everything seems to be ok.
  You said you play bad music. I think you mean bad quality music.
  Then I n t wonder some frying noise seems to play this kind of music.

  *@bzsolt*
  I recommend reinstall the operating system, because I noticed a similar problem on my laptop and after a fresh install, everything was ok.

• activation of the relay using rs 23

  Is there any sign of low cost in which a relay can be activated through labview with rs 232 communication. Please let me know as soon as possible.

  I need to acivate for a 5V with a labview timer relay and it should be communicated via rs 232 for the relay card.

  Looking to change your relay specifically by RS232, or simply by using the serial port?

  If it's the latter, then take a look at the "Troubleshooting Serial Line Monitor.vi" in examples of LabVIEW. With this, you can control the DTR (4 pins) and lines RTS (PIN 7) of your serial port and use them to move from a transistor or FET to control your relay.

• ACS 5.3 - Active Directory - limiter/DCs use to auth

  Hi all

  I have a Cisco ACS server deployed for GANYMEDE and RADIUS authentication for end-users.

  Everything works fine, it is joined to the domain, most of the time people can auth. However, it seems that the ACS is trying to auth against * ANY * DC in my field.

  DNS.findsrv FindSrvFromDns runs and draws from each domain controller to use. Not all of them are accessible or not fo all of them have the same structure of the user.

  Is there a way to specify or limit/control which domain controllers are queried?

  Hello

  Unfortunately at this point there is no way to control which DC should be questioned by the AEC. The ACS will retrieve all the available DC on your AD domain name and contact one of them.

  An enhancement request is already listed and developers are working to include the feature on future versions. Here is the information:

  http://Tools.Cisco.com/support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCte92062

  ACS should be able to query only the desired domain controllers

  Symptom: Currently in 5.0 and 5.1, the ACS queries the DNS with the field, in order to get a list of all the domain controllers in the domain and then try to communicate with each other. If the connection to even one domain controller fails, the connection of the CSA to the field is declared as failed. Many clients ask about this behavior change. It should be possible to define which domain controllers to contact and/or make GBA to interpret the DNS resource records registered by the domain controller Active Directory to facilitate the location of domain controllers.  Active Directory uses the service locator, or SRV, records. A SRV record is a new record described in RFC 2782 DNS type and is used to identify the services located on a network of Transmission Control Protocol/Internet Protocol (TCP/IP). Conditionsof : Domain with multiple domain controllers were some are not accessible from the security constraints given ACS / geographical. Workaround: Make sure that all domain controllers are upward and accessible of the ACS.

  Hope that clarifies it.

  Kind regards.

• Where the ACTIVE Control Panel

  where can I find the control screen to set the font size

  In general, you get the best results using the Zoom feature. Proportionally, this increases the text and images on a page and minimizes the weird glitches.

  This article describes how to use the Zoom for a given site: the font size and zoom - increase the size of web pages

  If you want to 'zoom' to all the sites at one level by default, you can use one of these modules:

  • Default FullZoom Level
  • NoSquint

  Or if the problem is with Firefox menu and text of the toolbar, rather than the pages, there is an another add-on for: police theme & size changer
