Boolean switch that are timed

I need to order a heating appliance to be switched on for 60 seconds and then be off for 120 seconds, and then the operation be repeated for a number of cycles. My main loop works continuously with a delay of 50 milliseconds, and needs a Boolean signal from switch continuously, so there is no possibility to place a hold or time out function in this loop. When I try to call a Subvi, which has a delay, the output of my main loop would be delayed. Anyone would be able to recommend me in the right direction.

Do it like that. It initializes the value False, after time, happening to True, and so on.

This could use some cleaning with nodes Select, but it does the job. The result is False for 120, then True for 60 seconds, rinse and repeat.

  • Configuration of virtual switches that are not updated

    In a vSphere infrastructure 5 based on 2 servers ESXi 5, I moved a few virtual machines to one virtual switch to another.

    Virtual machines work very well.

    If I use vSphere client and look at the configuration of the hosts (host and cluster-> Configuration-> Networking) I see some VM as they were connected either the old virtual switch and the new virtual switch, while they are only connected to the new virtual switch.

    I press "Refresh" without any result.

    If I look at the properties of each virtual computer, I don't see the link to the new virtual switch.

    How can I solve this problem? It is dangerous, even if it does not affect VMs or virtual switches, because it can make operators make mistakes...

    Concerning

    Marius

    Nothing dangerous. You probably have Active snapshots on virtual machines. Once the snapshots are deleted, the 'old' vSwitch and port group will disappear.

  • definition programmatically switch Boolean so that a handler will act on this matter.

    Hello

    Is there a way to programmatically set a Boolean switch so that a handler will act on this matter? I use an interface developed by another group, with producer/consumer structure, as part of a validation of equipment. I want to create a separate vi that will control the GUI. Currently I can put the Boolean commands using an invoke node but the event handler does not react to them. My suspicion is that it's a mechanical action of Booleans. Is there a way to do this with to change the mechanical action?

    Pat

    Well, a switch is usually trigger (where the name!). You never said you try to use Boolean action latch.

    Yes, local variables and the properties of the value can not be used to lock the Boolean action because they are handed over to the State by default when terminal is read by the code, and if you would allow them to be read and put in several places, you generate a giant mess.

  • Timed Boolean switches with case structure

    I'm trying to implement a control for a switch that, when enabled, a signal of 'essential' lights up for 2 seconds and then turns off, as soon as the essential signal sat for two seconds that the VI should send say that the switch is turned on.  I can't get it work the way I want to. I think it might be a way to do it with a machine to States, but I don't know much about them.

    Hello

    I changed your Boolean lock so it will break again in the off position.  This stops the VI into the case again and again until turns off.  Then I added two registers to hold the values of the indicator to shift.

    I guess that my bias is that you would like to continue to operate in the while loop, which goes back to the case of 'OFF '.   If expand you this to a state machine, you might have several cases, shift registers would provide the 'flag' access status to other cases.

    It is a single method, it fits your application.  How would you install it in a larger design?

    Copy the snippet on the desktop, drag on the VI.

    Did you want the keyturn to turn on for two seconds and then have the activated LED light?   If so, you have to move the location of the indicator in the target time while loop, this will in turn while the target time loop times two seconds.

  • Control relay with Boolean switch using DAQ assistant 9481 - problems

    Sorry for what may be a stupid question but I'm stuck in quicksand.

    I use a relay module 9481 and have two external relays connected lines 0 and 1.

    When I create a digital output 0 line by line, I can run the test inside the express and activate the relay and turn off without problem.

    The generated block DAQ expressed expects a Boolean input of 1 d. (See attached photo).

    I want to connect a Boolean switch relay line disk 0. You can connect live not because the switch is Boolean and the input is Boolean 1 d - I'm a conversation in the pict.

    All plumbing lines display results, the relay never active.

    Any bunch would be greatly appreciated! Thank you

    Mr._Mechanical,

    Welcome to the Forums of switch OR this forum is generally intended for products OR-SWITCH [such as the NI PXI-25xx & NI SCXI-11xx], I think I know the answer to your question.

    I think the reason why it's a failure is the conversion you make generates a table of 16 Boolean [as the 'boolean to (0,1)' function creates a data I16 type] with your data more false data points 15.

    When you try to control the relay, he sees 16 datapoints are you Commander to a single port [channel] and so error out.

    My suggestion would be to use normal DAQmx digital output screw [with, he set up as ' Digital > single channel > single sample > Boolean (1 line) "] rather than the DAQ assistant.

    If you use the daq assistant, simply by using the function 'Building the table' will transform your simple Boolean data point in a Boolean array containing a single element.

    While the DAQ assistant is very easy to use, I recommend that you use the DAQ assistant, because this reduces the features and increases the execution time.

  • Toggle Boolean / Switch successfully after VI runs

    I use a stepper motor that changes direction during execution.  I currently have a Boolean control that sends a digital output to the correct port on the controller to reverse the direction.  I do have, however, the Boolean value of the 'real' to 'false' or vice versa after each race, so the engine knows to reverse.  Is it possible to code this in my VI?  Basically I want my VI just to understand what the Boolean value is set to the "and" at the end of the switch of execution the value of the Boolean value to the opposite value.  If my code is needed it can be provided.

    Sorry I don't have LV8.2, you could post a version recorded for this or my guess is that with the posted code there are a lot of people who could help you very quickly.

    Here is an example of the two methods I described.  The while loop with shift register is a bit more general, I use it when I want a value "remember" when I run VI again.

  • How to detect the correct sequence of Boolean switches pushed

    Hello

    My program is all what I want too. However, I need to have the Boolean switches (digital inputs when wired to the equipment) be detected in the right sequence. There are 16 switches on a Board of material. The test subject is displayed 3 colors before hand and the sequence of buttons to push when prompted on the screen with one of the colors, each color pertains to a specific sequence of 4 switches pushed on 16 as quickly as possible. The sequence of buttons remains always the same according to the three colors red, yellow, blue.

    In the program, which is 99% working properly I tried to use a sequence of plate. It will give me a real if I hit the switches correctly - but will also give a real if I hit them back etc... I thought that a flat sequence is read from left to right?

    Then I messed around by using a structured event - the array of switches, pushed index and compare it to a table of values control. I understand how it works, but the correct code is elusive.

    I have attached a picture of program I did but it lacks the proper sequence. (Flat sequence)

    I have included the code for the structured event that I messed with. Don't laugh - I was just making experiences - I've never used a structured sequence before configuration.

    Hope someone can help me.

    Ned

    Hi Ned,.

    Your producer-consumer model is actually very close to work.  In the original version of screenshot, it seems you are trying to use the structure of sequence to capture the order, but in reality you will capture only the AND logical of all the 4 buttons with no information about the order in which they were pressed.  The structure of sequence does not by itself is waiting for an event to happen inside the frame, it which means that all 4 frames read as fast as the processor moves to their reading - which will be very fast.

    I've made a few changes to your VI and renamed him Rev 1.  See if it makes a little more sense with the notes I made on the front panel.  I also did a different version with a loop simple and some added functionality (-Ko), just in case Your ' e interested in another way to look at it.

  • How do switch you between 2 numeric values using a Boolean switch?

    Hello

    I'm a newbie to labview, so it is perhaps easy to answer.

    I would like to perform a calculation which, according to the test unit, will require a different numeric value to use in the Calc.

    I tried to use a Boolean switch to choose which constant must be used during runtime mode as well for example or 0.01 or 0.02 will be selected. The idea is to labview so insert the constant selected in the calculation and spit out the answer.

    There is only one output on the Boolean toggle switch and not of entry so that I can't work out how to do it. If there were 2 inputs and 1 output it would do the job.

    Thank you

    What should do?

    bisso92,

    You must be more specific...  When you say that you want the cover to be visible when it is called, I suspect you mean sub - vi.  You can go to the menu:

    File > properties VI then select the appearance of the window, followed to customize and select "display panel when called.  You can also select close thereafter, while initially closed.

    There are other "tricks", such as the incorporation of secondary school within your main VI, in this way, you can see both.

    Normally, a hand VI (or main function in other languages), would still present so that the operator can perform other operations.  If so you should look at using a Structure of the event with a producer / arrangement of consumer, where the consumer in a loop has the case structure where the sub-vis.

    To learn more about LabVIEW, I suggest that you try to watch some of these tutorials.

    Method 2:

    Try the SFC scan on the computer in mode noraml.

    SFC/scannow is a very useful command that you can use in any version of Windows. When the SFC (System File Checker) command is used with the/scannow switch, the tool analyzes all the important files of Windows on your computer and replace if necessary.

    Missing and the corruption of the operating system (like many DLLs) files are probably the main cause of the major problems of Windows. In view of this, plus the fact that the SFC/scannow is completely automatic and very easy to use, the tool should be usually one of your top not troubleshooting.

    If your computer is pre-installed with Windows 7 Home Premium, you should have a recovery if partition:

    New computers coming often pre-installed with Windows 7 have what is called a recovery partition. This is used to reinstall an operating system in the case of a system failure. To access it, you need to start when you start your computer by pressing a function key. This can be either F1, F2, F9, F10, F11, F12 key DEL or tab. See the manual that came with your PC for instructions on how to reinstall Windows.

    This is how the recovery partition is accessible to most popular brands...

    For Dell, press CTRL + F11 directly after switching on the device

    For HP, press F11 directly after switching on the device

    For LG, press F11 directly after switching on the device

    For Toshiba, press and hold "0" BEFORE and during the power upward

    For Acer, press and hold ALT + F10, as soon as you see the logo

    For Asus, press F9, as soon as you see the Asus logo.

    For Samsung, press F4 to the power upward...

    For Fujitsu, press the F8 key directly after the power

    Advent, restart your computer. Then, press F10 repeatedly until the message "Starting system recovery"

    Sony VAIO, reboot and press "F8" or "F10" repeatedly until the screen "Advanced Boot Options".

    ------------------------

    If the recovery partition is damaged or does not, you can then use the downloaded Home Premium as an alternative.

  • Is there a way to loop through the properties of a layer groups and JUST get those that are visible?

    Hello

    I'm trying to get just the property groups that are visible to a layer in my script. Is there such a property?

    For example, when I loop through groups of properties of a shape layer, I get masks, layer, surface Options and Audio property groups Styles, when none of these are appropriate. I tried to use the (.elided) property, but it gives me just the 'Content' hidden folders within the groups of vector and 'Masks' in 'membership Options '.

    * on a side note, I got the error "not"adjustable expression"with this property, because the property is a property of the parent is hidden." When you try to access X or Y Rotation on one layer 2D. It makes it seem like there is somewhere a Boolean value 'hidden' in the property object, but I can't.

    Hello

    'elided' and 'hidden' both have purpose UI (make the lighter user interface) but are very different:

    • 'j' is a static property groups attribute (readonly, and After Effects never becomes the value internally).

    The children of an elided group are not necessarily élidés.

    • 'hidden' is NOT an attribute, is dynamic and "undocumented".

    The UI of effects after mask everything that is not necessary in the layer property tree (for example the Group of hardware options is hidden when the layer is not 3D, because it is not used anyway).

    Properties and masked groups are always there and is accessible by script, you can read their values and attributes, Scout their subtree of property, but we cannot define anything on them or select them (in both cases, that an error is generated).

    And the children of a hidden group are hidden.

    Since there is no corresponding to 'hidden' attribute, it is uncomfortable to know whether or not a property is hidden. I only see one case of 'treatment '.

    For example:

    myLayer.layerStyle is hidden? <===>! myLayer.layerStyle.canSetEnabled

    myLayer.transform.xRotation is hidden? <===>! myLayer.transform.xRotation.canSetExpression

    myLayer.mask is hidden? <===>myLayer.mask.numProperties = 0

    myShapeLayer.content is hidden? <===>fake (never hidden, even if it is empty)

    etc...
