• 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.

• 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

• 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.

  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.

• That is producing this error: MuseJSAssert: error calling the function switch: Error: Invalid argument

  Website: http://lovehopemercy.org/

  In my navigation header by clicking on the option "VISIT US", that is to say generates this error: MuseJSAssert: error calling the function switch: error: invalid argument

  The other options do not work correctly. I get an error on export as HTML of MUSE, but the link works fine in other browsers. I download using Dreamweaver CC 2014. Reversal function works fine; it's the direct click of the menu item at the top that causes the problem.

  Did I miss a bad link or something that I can fix?

  Thanks in advance.

• Boolean switch node property in the Sub - VI

  Hi all

  I have a main vi and one under vi.  In my Subvi, he gets a Boolean value from the main vi through property node (see table).  The Subvi queries the Boolean reference until it gets a real.  Apparently, when the Subvi is running, it is not detect changes in the Boolean main vi.  Why is this?

  If it's a Boolean latch, you will get error 1193 whenever you try to read its Value property.  I noticed that you are not checking the output of the reading the property value error, this is why I guess that's the problem.  Read/write, the Value property of a latch that Boolean is not taken in charge.  You will need to pass the Boolean value to use the mechanical action switch... or you will need to find another way to transmit information between your screws

  For more information on the mechanical action of Boolean values, see this help document.

• Steering switch error

  Dear all,

  I get the following error when you try to create a new virtual switch Exec feature. I also have similair reported errors when you try to use current virtual devices that worked for a while with no problems.

  Can someone shed light on why this happened and what I can do to solve it? All the other functions and Labview code work as expected.

  

  Thank you very much

  Matt

  Thank you very much English.

  I had changed the Alias of Visa for the switch (logical name IVI = Eagle_Audio_Matrix), but failed to change the descriptor resources on the Hardware tab in the pilot session.

  Obviously a slightly more informative error message would have helped, but I'm happy that now it works again.

  Thanks again.

• Change 'DisableReportGeneration' boolean runtime error macro...

  Hello world

  In the SinglePass model, I wish to draw the attention of the user if the report generation is disabled and the opportunity to turn it on for this sequence is run.

  This is done as the last step of the sequence to get the report Options.

  To relight, I write false to: Parameters.ReportOptions.DisableReportGeneration

  But then, TestStand hesitates a few steps further with the error: "list macros used by the expression of the report file path cannot be changed during execution.

  Any ideas what I am doing wrong? All I have changed is a Boolean value in the parameter container ReportOptions. It's not legal?

  Thank you

  Ronnie

  

  Believer,

  I agree that 'Change of list of Macro' verification should not mistake when you have enabled the generation of reports. It is a bug and we'll fix it in a future version of TestStand.

  As a solution, reminder of report options, you can add an expression to set the 'Parameters.ReportOptions.CheckIfMacroListIsUnchanged' false, whenever you have activated ReportGeneration.

  Hope this helps

• Boolean switch until the released counter + the number of cycles

  Hi, I want to use a Boolean command button (switch release) to rely on a specific value and when obtaining this value (while pressing continuously the button) to turn on an led. If I release this Boolean button, I want to count the time until a value and then to turn off the light, like a hand for a hand detection dry.

  I was thinking of using the number of cycles in a sequence of plate with a delay for the time being I want to split on a matter of true or false, but the problem is that the count of the number of cycles is continuous and not slaughter not on the specific value I want for the power button truning the seeing.

  Any help?

• 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.

• 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.

• 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.

• Boolean switch rendering time.

  Hi all

  I have LabView of issue of a signal of my USB-6501. The output signal triggers a relay and turns a solenoid switch.

  Currently, I have a Boolean value, implemented as a button where to click to activate the signal, then click on to turn it off. In turn the valve opens and then closes.

  I am extremely inexperienced with Labview and was able to find enough to implement, but it is difficult for me to convert what others similar, but different set ups, have made the forum search.

  What I have a problem with now change this code in order to have clicking on the Boolean output affects the signal for a while (let's 500ms) and then turned off automatically (without having to set). Basically a pulse. I feel that this would imply the loop any set with a timer, but I'm not sure how to start setting this up.

  I have attached my LabView code for you to see. I would appreciate help. Thanks in advance.

  I recommend using a Structure of the event.  On the change of Boolean value, you set or reset the output.  Using a registry to offset, you can also set the timeout for the structure of the event.  Then in the timeout, use a Value property (signs) of the Boolean to force a change in value to the Boolean false.  This will result in event of change of Boolean trigger and consequently cause your output turns off.
