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.

Thanks for the reply. I solved the problem by using a component electric H bridge and related lines Mydaq DO0 DO1

  • reverse the engine problem!

    Hello! ...

    I have developed a program that has the algorith as follows:

    1 x steps and Y steps determne table of pixel size I want.

    2. for each Y increment the X scan by a fixed number of steps, then there

    3 step 2 is repeated until there is reached its MAX State.

    Problem:

    After the scan X say 10 steps I want to reverse and go back to the original, and then again after Y increments X scan and return to original.

    Its a RASTER scan basically.

    I'm not able to understand why and how to add a part to get the engine back to its original position.

    Please find the VI and tell me my mistakes.

    Thank you

    Hello

    You have two nested while loops: one that moves in the direction y and one inside that moves in the x direction.  There are two ways you can implement replacing the x-axis zero.

    1. the stop direction x loop condition is once he traveled to the stop.  You can add that a deal right behind what just loop said the engine back to zero.

    2. in management's loop before the axis x running tell the x axis to return to zero.  This would lead to zero each time before axis x begins his move.

    Both ways will accomplish the same thing but got it back after the move and two the fact before.

  • How to reverse the direction of scrolling using the mouse wheel which is simillar to 'natural' scroll of MAC

    I use the latest version of Firefox (31.0) on Windows Pro 8.1. I wanted to mimic OS X way of scrolling in the window of the browser called 'natural' to scroll. I edited the registry setting for my logitech mouse and scrolling works perfectly as I wanted it to every single window on my system with only one exception, the Firefox browser.
    Somehow, Firefox is configured to use the old method of scrolling and does not respect the registry settings of windows, as all other windows.
    Is it possible to change or reverse the direction of scrolling?

    Thank you
    Roman

    Roman Hello, try this: enter about: config in the address bar of firefox (confirmed the message information where it appears) and search for the preference named mousewheel.default.delta_multiplier_y. Double-click it and change its value to -100.

  • 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,.

  • Reverse the direction of the pasted path?

    I have a path on a shape layer and I copy this path in the Position of another layer (so I can animate this layer along the way).

    But I need the inversion that moves the stuck position.

    So I need instead of the movement object to the right, left right left.

    I tried to change the setting of 'Reverse Path Direction' on the path before copy/paste, but who don't seem to do anything.

  • 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.

    In the last image, it is a small flat sequence with the button stop running to ensure that all relays are extinguished in the case where the program Stop button by wire a fake to the local variable.  Excerpts from VI transformed into nodes of property with controls to control wired in them reference.

  • SRM 5.5 - vSphere replication - error: impossible to reverse the replication for the Virtual Machine. A snapshot operation cannot be performed

    Hi all, we have just run a test DR failover of a couple of virtual machines in our protected our failover site and all site swung perfectly, two virtual machines came online and all applications work well. However when we cam to r-eprotect machines virtual, we get some errors.

    One of the virtual machines seems to have lived the reprotect end process, it is still running, but has not moved to 89% for some time. The virtual machine has a couple of grand (a little less than 2 TB) VMDK. slow progress is just a consequence of the large VMDK?

    More worrisome is the virtual machine which don't reprotect at all. It generates an error whenever I click on the "Restore" button (error: impossible to reverse the replication for the Virtual Machine.) A snapshot operation can not be performed).


    Does anyone have any ideas as to the cause?

    Thanks in advance for any help.

    Andy

    Finally got to the bottom of this. The issue was that reprotect SRM work was trying to dispel any snapshots that were taken on the computer object virtual destination in VMWare, but could not clean snapshots.

    The reason why snapshots would not consolidate was because it was snapshots of temporary VEEAM who in fact any snapshot file listed in the VSAN data store. So when we looked through the browser data store, no snapshot file existed in the virtual computers folder. Trying a manual removal also failed.

    To fix this, we created a snapshot of the virtual machine in the original data center (note is the engine to the bottom of the virtual machine), this effect was to get rid of the 'fade' snapshot that was visible in the Snapshot Manager that VEEAM backup had left behind. Once this had disappeared, the reprotect back to DCA worked perfectly.

  • Reverse the flow of the text along a path?

    I have created a path to the oval text using a shape tool.  When I type along the top of the track, the lettering is flowing as it should.  When I type the lower part, it is upside down and backwards because the stream is the same as the top.  How to reverse the flow of the text at the bottom is the place and reads left to right?  Can't find info on how to reverse the direction of flow.  Thanks in advance for your suggestions.

    pjcaver

    OK, finally successful: Type around the top half above the lettering.  Reposition the tool text down and continue typing, even if upside down.  Select the path Selection tool, drag the text down to the INSIDE of the oval that will right the text correctly.  Select the text that you want to go then it appears highlighted, go to the window "Select the vertical offset" (not the slider to the left of it) and press down as many times until it is aligned with the bottom of the oval, in my case about - 5.  For larger slices of movement, hold the SHIFT key while pressing the down arrow key to count 10 movements.  The upper part of the lettering will line up correctly with the oval shape.

    Thank you, Trevor, for the right direction to follow.

  • Reverse the factory setting

    I have a phone that was given to me from my father-in-law, it's a phone of one of his former employees that was great in the office. We had no password information, so we tried to reset the phone to wipe and start over. This just finished sending us to a factory setting that requires an Apple ID and password that we don't have. How do I reverse the factory setting, so I'm back to the regular functions of the phone?

    Sorry, but you can't. This device is locked to the previous owners iCloud account and password activation.  Without their password or their active assistance to disable locking activation, will you not be able to use this device.

  • HP Envy 17: Reverse the function keys

    Hey guys,.

    My laptop is a very good laptop, with a good graphics card nvidia an i7 cpu and even 16 GB of ram. Even with a 17 inch screen full HD 1920 * 1080, making incredible games! Even GTA V for Pc works quite well on this laptop powerful.

    All of these things are an amazing gaming PC, however, it has a match no one back which makes it almost impossible to play a game with good fluidity.

    Present a defect of fatal game is actually the keyboard, but to be more precise, it is the function keys. The HP Envy 17 has two F1 - F12 and INSERT key. However, these are the secondary keys. Primary keys are keys system that changes the brightness or volume. That means if I want to use F2 in a game, I have to hold the function key, and then press F2.

    This seems minor, but when you play, it can be annoying to have to hold down a function key just to use one of the F keys.

    Dies, does anyone know how to get this fixed and reverse the trend, in this way if I want to cut my cell phone that I have to press the function, then the F6 key. I hope that people know what I mean and please if you know of a fix would be great if you could post it below.

    Thank you
    Connor Burnett.

    Hello

    Yes, I used the F1 - F12 keys on a daily basis for the last 35 years or so, but fortunately I always use external keyboards using laptops (on or off a docking station). You may not share, but disable. Please use the following article:
