• Value of cluster lost when you leave the structure of the case

  Hi all

  I'm having a problem with a particular VI I'm working. (FYI it's in Labview 8.0)

  The VI is set to run a current source, voltmeter and thermometer, then recording and graph the data in various ways that can be selected by the user.

  Everything seems to work fine except a particular graphic method. When I try to graph current compared to the tension, the current value is lost estates. In a case the current and voltage are combined to form a cluster, and then leave the case structure to be later appended to a table of cluster.

  However, the value of the cluster is lost when the chart is set for the voltage vs. Any other method and it works correctly.

  I can't understand why this is happening as it does not make much sense than other methods of work charts, but this one isn't when it is coded the same exact other than having the different variables.

  I have attached the VI with added indicators showing that the value of cluster is lost once he leaves the box structure. Any help would be appreciated.

  Thank you very much and I apologize for my extremely messy VI.

  You really need to boil this down to something we can run and reproduce the problem.

  Have you tried to break a few relevant connections and rewire? Something is possibly corrupt.

  Besides being a mess, your VI has quite a few glaring errors.

  Let's take a look at the structures at the top right:

  • 90% of the code is the same in all the structures of three cases, so all that needs to be inside the structure is the small part where you built the table 2D. All the rest is outside of the case.
  • The structure of the sequence has no useful function.
  • Why do you need to reverse the table with each iteration of the small loop FOR? Once before the loop would be sufficient. Right?
  • Why you use table built inside the small loop FOR, but no autoindex on the edge of the loop? All you ever get is an array containing exactly one element, no matter how the loop runs. Seems unnecessary! (see below for an alternative image).
  • You wouldn't even need to reverse if you want to use "built the table" instead of "insert into the table at position 0" in the central part.

  

  Other: You constantly hammer all nodes of your property. The only need that will be called when things change. Again, you have far too many cases. For example, in the structure of the case where you are having problems, the same nodes of property exist in all cases. A single instance of the property node belong outside the case and only the string inside each case constants. Whenever the code is the same in all cases a case structure, which code belongs to the outside!

• Using a value Boolean true to increment a counter

  Hello world

  I would like to make a simple counter that waits just until a value Boolean true is passed and account 1, then wait until it happened again and goes up to 2 and so on. Just a single increment each time a real rose. I'm sure it's pretty simple, but I had no luck so far.

  Who does not resemble a need for a secondary loop.  You can add code to this loop to analyze the data.  If you do the calculations to determine a true, you already do the job.  Instead of going out a real, just increment a value of a shift register it.  Saves the hassle of sending one real constant for another loop for updating a shift register.  Do not create excess code just to have more code.

• How Photoshop converts the RGB 16-bit values to 15-bit and 8-bit?

  Can someone please help me understand what rounding of diet or another algorithm is used when Photoshop reduced a 16-bit color 8-bit?

  For example, the two colors (was and B) are the colours of 16-bit swatch taken directly from a file of the ACO:

  A16 = (61603, 60948, 58982)

  B16 = (58326, 57015, 52428)

  Photoshop displays the values of "16-bit" (acutally 15 bits) as well:

  A15 = (30802, 30474, 29491)

  B15 = (29163, 28508, 26214)

  It seems that the 15-bit values are the result of the division by two and rounded to the nearest integer.

  With 8-bit, it's another story although:

  A8 = (240, 237, 229)

  B8 = (222, 227, 204)

  Now, if we divide the 16-bit value by 256, the following:

  A8_float = (240.6, 238,1, 230,4)

  B8_float = (227,8, 222,7, 204.8)

  It's a similar story during the allocation of the 15 by 128 bit values. No system rounding or truncation will get the same answers as Photoshop for 8 bit I see. What I can't work, it's how Photoshop calculates these figures. It's the division of integers, floating point division with rounding or truncation? I'm puzzled. Help, please.

  -> range 32768-65535: (32768 * x + 32767) / 65535

  Not quite dividing by 2, otherwise you miss the white point.

  32768-> 255 range: (255 * x + 16384) / 32768

  With the exception of dithering, it is all simple mathematics.

• Set the value of cluster control in secondary school

  Hello

  Is there a way to set the value of control from one cluster to a high school?

  I enclose my screw in LV8.0

  Charly

  If you have a reference to the VI being put into secondary (which there or it is not in the secondary, right?) you can use it to get a reference to the façade of the VI. This in turn will allow you to read an array of references to all the controls and indicators on the front of the Secondary VI. Cross this table by looking at the text property of the label: for each reference in the table until you find the one for the control of the cluster.

  Now, use the specific function to more class to convert reference generic control of the pole to a cluster reference. You can use it to get an array of all the controls within the cluster. Now, go through this table by looking at the text property of the label: for each reference in the table until you find the one for control quevous want to set and you are there...

• How to case statement based on the array of values of 3 or more?

  I'm trying to figure out how to do a comparison or case structure... based on the creation of an array of boolean 3 (or maybe more).

  I have a table (it's from a serial connection, and I am conversion back to a table to work with) [t, F, F] in this case I would like to display on a status indicator "STBY".

  If the array is defined on [F, T, F] I want to display in this indicator "ON".

  If the array is defined on [F, F, T] I want to display in this "EMPTY" indicator

  I can not understand how to compare combinations of things... I read in an array of bytes, and the first 3 bits in this example, determine what to display in a status... I can't figure out how to do with structure case... or without some channels to research and/or bad comparison...

  Any suggestions?

  Thanks in advance,

  You can use search 1 d array and find the first real.

  Or you could convert the table of Boolean integer U8 and integer that results to determine which cases to run.  (4, vs, vs 1-2)

• How to write values to cluster of indicators (tank sliders)?

  I'm writing a table 1 d of values to their 8 sliders matching tank.

  So each element of the array is displayed as the value of the slider.

  How can I do this?

  This works if you view in a cluster of numeric values, but not the sliders.

  I also tried to write the table to the 'value' property of each of the sliders, but still doesn't seem to work.

  Any suggestions?

  001,

  How did you create the sliders? They are actaully the clusters of two elements, which appear to be identical cursors sitting on top of the other.

  This is probably why you meet your data of wiring to them so much trouble.  I suggest that you create a new cluster with standard cursors.  Then, you can use the table to primitive Cluster to move the data.

  Two caveats: 1. table to the default Cluster is 9 elements of the cluster regardless of the number of items in the table.  Pop - up on the release of cluster Terminal to change the number of items if necessary.

  2. you have apparently added items to the cluster inoperable.  The order of cluster is important if you want to get the data in the right places.

  In addition, it would be much easier for us to test your code if you included table 2D input data.  Put the data here and then change > use current default values. Then save.

• % Use CPU (request) value in Cluster capability risk Widget in vC Ops. VAPP 5.8.1

  Hello

  We strive to understand a value in the table for the Cluster risk widget detals of capacity. % Use CPU (request) is one who gives us in the array of two values that is 37% /(72%). I can understand the value without the braces, but not inside them. Is it a request, is UC value - this a derivative metric vC Ops calculates for us?

  What he learns and how should I interpret it?

  For some clusters, we see double the value inside the curly brackets as % cpu usage and not stress but with allocation of CPU redmarked % with a very high number (more than 700%).

  The image is not taken from our environment.

  

  If anyone has knowledge on this subject and maybe a source where to find more information, it would be apprecierad.

  See you soon,.

  The rest of the CAP does not resemble costop or claim in 5.x. If your cap rem is 5.5% and time rem is 1 year, it is because your evaluation period is too short. The cap rem is the latest state of the collection, where as rem time is based on the period of analysis/trend... for example the bucket size and quantity.

  If you want a better analysis. you will need to attach a pdf file of the report/view you see so we can see all the configuration policies.

• calibrate the values of 12-bit ADC

  I'd like to understand how to convert integer values of a 12-bit ADC in tensions. I use a box NI USB-6008 in differential input mode. It is 12 bits of resolution in differential mode.  I use a simple VI to collect 100 samples of the differential analog input voltage 0 (AI0).  When I connect AI0 + and -AI0, the tension between them must be zero.  When I traced the number returned by the routine of the CQI data, I see-32768 values most of the time over a few jumps to + 32752.  When to convert format I16 U16 format numbers. I see values ot + 32 768 for the most part, as well as a few jumps to + 32752.See attached shot of front block diagram of the display panel.

  Looks like Labview add 4 zeros at the end of the right hand of the binary number 12 bit returned by CDA.  Is there a simple way to make ADC return numbers like 0, + 1, -1, when the voltage is about zero?  I could do the following:

  1 convert the values returned by the ADC since I16 to U16.

  2 divide by 16.

  3 subtract 2048.

  I teach students about the basics of analog digital conversion, and I don't want to have to explain this clumsy scheme, if I can avoid it.

  Thank you.

  Bill

  Hi Bill,

  Looks like you've discovered the complement representation two that LabVIEW uses to represent signed integers. Not adjusted data are drawn directly on the hardware registers and are represented as they are on the unit.

  If you want to convert the values, you can convert as you have indicated. You can also take the opportunity to explain the complement to two of them if it's as part of your course, or you can just put the arithmetic in a VI if you want to hide.

  If you look at the unsigned values, you could also explain to them that it is in the voltage range, the value is.

  For example, 16-bit unsigned gives a range of 0-65535. If you have selected the voltage range is-10 to + 10 v. If you have 0V, so you should expect a reading around 32768.

  Here's the wikipedia article on the complement of two for reference: http://en.wikipedia.org/wiki/Two's_complement

• Boolean logic: Bit of activation & deactivation

  Hello

  I know how to turn a bit (bit high set) in LabVIEW.  ********

  For example, let's say I have 101, and I want to activate the Middle bit.

  To activate the Middle bit, I would use the OR operation.  101 10 OR that would produce 111. I can do that in LabVIEW.

  Check the attachments.

  Can someone tell me how to disable some (low bit set) using LabVIEW?  ******

  Now let said I 111, and I want to disable the Middle bit in LabVIEW?   I know that I should just use and operation.

  111 with 101 will 101 AND.   I don't know how to do this in LabVIEW. Please HELP.

  Do you almost exactly the same thing you did to turn the bit. After the 2 ^ n function, reduce to zero the result (using Boolean does NOT work), which will give you all the bits set to 1 except the one you want. Then, you can use AND put just this bit to 0.

• Build an array of values of the difference

  Dear members,

  With reference to the attached LabVIEW 2010 Student Edition file...

  From the incoming data via the .csv "Reading of the spreadsheet", I want to display a picture of the difference between the n and n-1 data value if the data set is 10, 20, 25, 35, 50, then the difference will be 10, 5, 10, 15.

  I used the "Index Array" function to extract the n and n - 1 values (using the function 'Simulation' as the incrementer line index) however I can't find the way to build an array of these difference values and display them in the façade, which is

  It will probably be a trivial problem for more experienced LabVIEW programmers.  Advice or assistance is welcome.

  Kind regards

  Since you have 1 column of 800 lines, then use table to Index first to get only the first column.  This will give you a table 1 d of 800 items.  Then the idea to use this table, as well as the subset of the table for the 2nd through the remaining lines, subtract one from the other, work.

  I can't comment on the simulation loops because I don't have that and never used.

• Using the values of cluster in a formula?

  Hi guys,.

  I can't try to use the unbundle after values of a cluster in a formula. This cluster is to colect and validate the values of the user. After that, I will need these values to insert into a formula, but the formula does not recognize the values. Any suggestions for this? It asks me to change the input and output, how do I do this?

  Thanks in advance,

• Find an attribute value Boolean inferred at a given date in the past

  Hello

  Need advice on below:

  Looking to find a value of the Boolean attribute to a given date in the past.

  Ex: [b1] condition A is true if

  age < 18 of the person and (the age is calculated using the date of the assessment [this is a basic attribute spent] year subtracted by year Date of birth of the person)

  the person has met the State B (may be that there is a finding of another rule that serves here as a condition which, in turn, uses the date of assessment)

  Looking to find if the [b1] was true at another date in the past. (for example a 6-7 month date before the date of delegated review)

  The function according to temporal but he explores always give the date [b1] value assessment and not the past date we want to find the value of.

  Thank you.

  In the example, the conclusion rule (condition A is true) will have a constant value (true or false) if there is no temporal logic feeding, i.e. no attributes with temporal values and no temporal function. However, if 'the person we met condition B' has changepoints, then it will be the conclusion.

  For example, if the value of ' the person met the condition B is initially 'false' and become 'true' to a point of change on 01/01/2014, then "condition A is true" will be set to 'false' at the start and 'true' 01/01/2014.

  Temporal data in the Debugger entry: http://docs.oracle.com/html/E48373_01/toc.htm#Debugging/Debug_temporal_rules_and_data.htm#Enter

  Temporal reasoning can be very powerful when used correctly, but most of the time it is exaggerated and made just the things more complicated than they should be. Most date calculations can be addressed with functions and logic of regular date.
