Powder dosing machine? Direct control of the engines?

Hello world

I hope it was not shown below, but I start my worki with nxt and labviev and a certain problem.

I want to build a dosing of powder, which consists of two conductors of powder (driven by motors) and the weight of lab controlled by RS232.

The goal is to be able to make precise mixtures in order to weigh the empty box of weight, tare, and then adds a charger of the weight of the powder (A) checks how much gave - if not enough adds some etc... etc... continued with 2 powder and mix to...

The problem is that I know that I can write the labview NXT program to run the NXT brick, but it would be very complicated to use - the best way would be to take direct control over the engine via NXT - therefore when I want the engine to move a few degrees it should not start the program in the nxt brick do the program level LAbview... IS this possible? Can I use brick NXT as a controller of engine itself?

Thank you

Marek

Marek,

This is possible in 2009 in Module NXT and NXT earlier toolkits.  In 2009, just write your code NXT in a VI that is not the target of the NXT (e.g. it is targeted at the Instance of the Application My Computer/hand).  The VI NXT know when they are targeted on the computer and automatically send direct orders to the NXT brick via USB or Bluetooth.

In previous versions of the tool NXT, you must use the Direct screw of NXT to accomplish the same task, which is not as transparent as the new method, but all works the same.  Please let us know if you have any questions about how to apply this.

See you soon,.

  • A USB from a PXI power control, turn the engine in real time

    Hello

    I need a USB of my target in time power control real (PXI) who installed the engine time real Labview (no windows installation).

    If I'm not mistaken, this is not possible with the USB port on the controller (NI PXI-8108) that I have not installed windows to recognize the device.  As far as I could see, it looks like I need to buy a special card for PXI that allows me to interact with USB devices.

    With ESXi the vSwitches work comparable to Bridged networking, so there is really nothing special to do.

  • Management control of the engine with proximity sensors

    I have two prox switches and two relays that I can control in labview manually, however I was unable to produce the needed code to "lock" or the relay that prox has been activated.  The application is very simple, I have a linear actuator that I run at the end of the race until it activates the switch prox "scope".  At this point, I want to activate the second relay to reverse the direction of the motor until it activates the "home" prox switch

    I know that someone will take about two seconds to bust the code but I was failing for about 2 days on this subject.  Any help would be appreciated.

    Thank you.

    Try this.  Proximity detectors and the relay outputs are simulated.  You will need to replace those with your digital inputs and digital outputs.

  • reverse the direction of the engine

    Hi, I need help with the following:

    Detection time and the weft: sensor of the LDR (photocell) should be able to detect whether it is day and night (light or dark). During the day, if the Sun is so bright, special curtains should automatically shadow through the engine temperature sensors. During the night, curtains must be retrieved automatically. Note that the user has the ability to override decisions could make about deployment or recovering curtains.

    I did a job on the vi program. However I don't know how to reverse the direction of the engine through labview. I'm controlling the speed of the motor using function (1 sample of Charron 1) freq counter DAQmx writing a command button. So I can't specify a negative cycle. Any suggestions?

    My labview code is attached.

  • direction of the motor controlled by the adjustment wheel

    How to control the direction of the engine using the adjustment wheel, for example, if the pointer locates the negative area, the engine was reversed.  Usually the engine management is determined by AIN2 and AIN1 values in the microchip, if the value of AIN1 is larger than AIN2, the engine would turn in a certain direction, otherwise, the engine was reversed. However, I would use only Dial control to control direction. What should I do?

  • The engine through series control

    Hello

    I'm working on a project that requires the operator to control the engine rpm and it is on and off a labview interface.  The engine is a Kollmorgen servomotor(AKM42E-ANDNC-00) that is connected to a controller of S20360-VTS of danaher. The controller is connects to the computer via the serial port.

    My question is if there is a way to control this motor through the connection in series of the computer.  I tried to communicate with is the use of channels but received only gibberish back. (I do really not understand communication channel).  The settings for the serial communication are correct (with the exception of flow control that I'm not sure).  Any help would be appreciated.  You will find info series beginning on page 57 of the manual of the controller.

    Thank you

    So, after having spent some time yesterday and today with Kollmorgen technology support.  I determined that t he car engine and cable series are actually owners and there is no way to interface with the engine outside of applications of Kollmorgen.  We tried to run commands and an engine test in Hyperterminal and Labview and the engine ended by locking for safety. Thanks for everyone entered btw, I learned a lot.

  • HP Pro Plus 6800: error 0 x, 00000057 wireless and wireless Direct properties of the Windows Control Panel printer - print a Test Page

    I have a laptop Toshiba Satellite of Win7 64 bit and a HP 8600 Pro Plus,
    update firmware and drivers about 2 weeks for the 8600 was a
    a long time I have been updated, which is connected wireless has decided to
    Direct to print Wireless Setup once the program installation, I tried to do a windows
    Print the Test Page in the printer property Panel, somewhat normal for
    set up a printer

    Under the connection of the conciergerie, I got the error message 0 x 00000057
    Under wireless direct printing, I got the same error 0 x 00000057

    After spending the time to check the settings, connections and asking
    Why? I decided to see that if I could print the docs, I print a PDF file,
    Notepad and Word documents in each application under the two
    configurations without problem.

    Under the wireless connection, I started the Web Services module
    and was able to make the impression within the Web Services Test page
    module without problem could not yet do the printing Test Page
    in the printer properties panel.

    I ran Print and Scan doctor who, to my surprise mentioned
    a conflict of Driver, I welcomed this program to uninstall the driver,
    went looking upward for the driver and the same driver was so done
    No download but to remove the driver and reinstalled the driver.
    Always error message here.

    I'm now tempted to delete a direct print wireless and see
    What happens if the error disappears, if she does not unstall all
    associated with the printer and do a clean reinstall. In case of emergency
    is there an alternative to the use of the Web Service module to the setting
    When not connected to the wireless network?

    I think that the Panel of the printer would do this (I'll watch this later

    spend enough time on it), or do I need to run Web Services to

    direct wireless installation, just think about this, otherwise I'll shoot

    a usb cable.  Maybe if I install Direct wireless on the printer control panel

    the message will disappear as the installation of the printer program, not software

    on the laptop?

    It is a minor problem since I can still print but question why!

    See other issues about this error message I thought

    spend my experience with this error.

    Always had a number of things to think and try, once again.

    If your getting this error message I would suggest trying a test page printed

    within the module of Web Service to see if the message developed.

    Could not back the driver so I removed the printer driver

    by deleting.

    19/07/2011 Date print driver
    Print driver version 26.0.0.0

    and removed software in Add and Remove software Hp also had to turn

    disable the wireless module directly on the printer to reinstall from the CD.

    Reinstalled printer/software form the CD supplied with the printer, the

    Driver date is 08/12/2009 Ver.9.0.0

    No more error in configuration.

    is the answer to the error message 0 x 00000057 or 0x00000xx

    associated with the driver? Or just the 0 x 00000057?

    Could not find a list of drivers between the driver and

    Will not update the driver for a good while or until I have too.

  • How to control the speed of the engine without tachometer

    Hello world

    Thanks for stopping by and have a look at my problem

    I have a PCI7344, UMI7764, DC motor, encoder and drive motor. Everything works fine. Currently, this system allows me to control the motor through feedback from encoder (which means, first I set my target position, and the engine will run to some targets detected by the encoder position).

    What I want to do now is to control the speed of the engine, however, I don't have a tachometer feedback, since my speedometer only allow me to display the number of LAPS. is anyway that I can do this (control and maintain the speed of the engine at a certain RPM value) with all the listed facilities I have. Can someone help me on this?

    Thanks in advance for any suggestion and recommendation.

    Using LabVIEW, engine behavior will not change. If you see massive oscillations, my first guess is that should change your settings of PID. Please refer to this document and the other pages that are linked.

  • Spooky: Front lost control of the scheme code

    I have a LabVIEW (Win7-64B LabVIEW 14.0 32 bit) program that behaves a little bit scary.

    On some occasions, while the LabVIEW tandis que le LabVIEW programme program is running, suddenly the front panel controls are no longer read by the process of block diagram. So that's what I see:

    • The program runs, processes the data, and updates indicators as expected.
    • The run button is in unmanaged mode even if the program continues to run.
    • The button abandon red is not functional - push has no effect.
    • The block diagram can be debugged, simple staircase and breakpoints.
    • The controls on the front panel are not read and the program cannot be stopped because it is based on the action of the Panel before doing so.
    • The run button is non-functional in the sense that it can be pressed in run mode, but he has no apparent effect on the State of the block already running diagram.
    • The only way to stop the program is closing the front panel.
    • The behavior occurs at random times, is annoyingly frequent, but not enough (frequent) to make debugging by elimination of effective code.

    The program is a construction of State machine using queued messages and access material cRIO via shared variables.

    I know that this information is rather rare in which case debugging suggestions, but in which direction to look for all ideas are welcome.

    Some of these could possibly be explained by things like the user interface is locked by a structure of the event or updates to defer property is set on the Panel or being stuck in a call from the DLL, but there is another option that seems to match your description a little: https://lavag.org/topic/17049-windows-aero-theme-and-lockup/?p=104728

    When I saw him it was in an EXE file, so I can't comment on things like execution of arrows, but it was definitely a case where the VI was certainly running and updating the user interface, but was not receiving updates of the user interface.

  • You must stop your request before the engine may stop

    I have an integrated application that uses LV DSC 6.0.2. The application starts and stops the engine tag programmatically. The application works fine, but on some machines, I'll get continuously the next dialog box when I try to stop the engine of the tag:

    "You must stop your request before the engine may stop"

    It's strange, because it only happens on some machines (it seems that it can occur on computers with ONLY of DSC Run-Time installed, not the full dev system. DSC LV).

    The dialog seems to refer to the application of 'control' which tries to stop the engine... it isn't telling me that my devices servers need to be stopped.

    This dialog box does not seem logical, I should be able
    to build an application that can start and stop the engine... and why I get this dialog on some machines but not on others?

    John Paul,

    There are two points that we should ask ourselves:
    1: you can have different loops while in your application where you read/write to and from the engine of the tag with the read/write Tag.vi. These screws has a stop of production which must be wired first the while loop. If you have cases where you do not connect this output to your time stop loop you could access the engine while you want to stop the engine in another loop with the Shutdown.vi engine. -> Make sure you have all drivers of DSC to access loops has stopped before you turn off the engine.

    2nd: I guess he was once an issue of race with the DSC engine condition and how it access to shared memory with the read/write Tag.vi. But this condtion of race must be agreed with the version of LabVIEW DSC
    6.1 or with other fixes for LabVIEW DSC 6.0.2. You can download patches (in this case, particularly the BVRTDatabase.dll) driver update page & of NOR: www.ni.com/support/ > Option 3, drivers and updates > Search drivers and updates > type 'LabVIEW DSC' > choose LabVIEW Datalogging and Supervisory Control 6.0.2 fixes.
    You must apply the patches of this as well on your DSC 6.0.2 Run Time System!

    I hope that one of the help of two suggestions to solve your problem.

  • vCenter vCSA unit lost, how to install a new one to take control of the host?

    Hello

    Due to a disk failure, I lost the VCSA control 2 guests. Now I manage the VMs entering each host separately.

    The backup did not work, so I want to reinstall VCSA 5.1 again.

    I read that the first step is to "unpin" the hosts of the VCSA.

    Is there a procedure for this operation? I want to reinstall and take control of the hosts and their virtual machines.

    Will this affect virtual machines running settings? new device "reads" the current configuration?

    I supported the VCSA configuration, but I think that it is not reliable because this time we made changes directly to the guests.

    Thanks in advance

    given that the old vCenter isn't available.

    and as you said that you are able to connect directly to the two hosts, so there is no locking mode either. nothing should be done 'Dismantling' part of it.

    Just prepare your new VCSA, connection inside once the configuration is successful using the vi client or web, create new data Center virtual

    and start adding hosts, the two hosts will be added without problem.

    New VC will be able to reset the account vpxuser password as part of the welcome add treat yourself.
