• How to convert the string with numbers in the table of Boolean 2D

  Hello

  I have input a string with comma separated numbers 1,192 (starting at 1).

  This string must be converted to a table 2D-boolean. Each number that appears should be true, not true rest.

  The 2D table consists of 4 times of 0.47 Boolean values.

  1.48--> [0.47] numbers [0]
  49.96--> [0.47] numbers [1]
  Numbers 97.144--> [0.47] [2]
  145.192--> [0.47] numbers [3]

  If a '1, 49, 97 145' input string put all [0] [0.3] true.

  How can it be easy/fast resolved?

  Thanks for help

  Break the string of numbers in a table of numbers.  (Spreasheet String to Array).

  In a loop For, index with each issue of this table.  Use in the range and Coerce to see if it is in the range of numbers.  (You can put this in a loop For as auto good indexing through the ranges).  If it's in the range, then use subset replace table to activate the corresponding item in a real.  If this is not the case, do nothing.  Maintain the table of Boolean in a shift register.

  Repeat this step for each number in your table.

  Hello

  Thanks to you all.

  I just got an idea and his work. It's better, I want to share with you.

  1. Convert the table of Boolean 0, 1 (available in boolean labiew)
  2. Just to summarize these 0, 1, using arithmetic sum
  3. Comapre the sum with half of the number of channels.
  4. If the sum is greater than or equal to, its ok

• little binary string in array (of TCP read) to the table of Boolean LV (and back)

  I would like to ask what is the easiest way for the next conversion? We use aTCP Read function to read an incoming binary string to a S7 API using LabVIEW. We know that LabVIEW stores a Boolean value to 8 bits. The incoming binary string contains 14 bits (representing 14 indicators of status). What is the best way to convert these values of 14-bit LabVIEW Boolean table?

  In addition, we send a LAbVIEW Boolean table in the PLC data (to write a TCP) string containing status bits.

  Thank you very much!

  Martins wrote:

  This 30 bytes contains some data more, including 14 bit flags (size is 14 bits). Since the PLC cannot put 'together' (16-bit) words at his side before sending data TCP, 14 bits is padded with 2 bits holding no valueable info.

  Then the solution is simple.  Take your 2 bytes and unflatten in a U16.  Then use Boolean table number.

• to convert decimal table table of Boolean

  Hey all

  I have a decimal table (or at least that's what I think it is).

  the table is 1010 (and the number of bits can change depending on the application)

  that 1010 is decimal. I want to convert that into a Boolean 1010, because I have to open close some ports in this logic.

  Help, please

  Thank you very much

  Well done more to give

  Your information is a little sparse, so I fill in some blanks by guessing...

  1010 is not a table (and no Boolean value either!)

  Is each figure part of the picture? What is the representation?

  If each digit is a digital element of the array, just wire 'not equal zero' to the table and you will get an array of Boolean.

  It might be easier if you can fix a simple VI which contains the table that you have and the table you want. Thank you!

• Table with numeric columns and string

  Hello everyone. I am a new labviewer, so I have 2 questions fundamental.

  1. I found this basic timer loop, which I need to get inside my structure of the event. How to wire this loop with my writing and reading?

  2. I need to wire my digital indicator "Elapsed time" with my table, so I want the 'measure' in the first column and "elapsed time" in the second column. I know I can't mix string and digital indicator in the same table, so the best way would be to make two tables 1 d (digital channel), or there are more basic ways to correct the problem?

  Thanks in advance

• Table of Boolean to the number

  I don't know if this has never been worn before, but if so, it's here once again.  Lets say I have a Boolean chart shown with 8 elements willing horizontally.  When I read it, I usually read it left to right, which means that the MSB is on the left and the LSB is on the right.  However, if I use the Boolean to number funtion table, this function read right to left.  Ditto for the number of Boolean function Array, it will form the table from right to left.  This goes against normal Boolean reading habits.  I know that this isn't a bug because it was probably intended to be run as such.  The VI below illustrates what I mean.  Three questions:

  Why is it done this way?

  Why not make the configurable functions to read in both directions?

  The term big-endian to Little Endian applies to the order of the bytes in a word of 16 bits, divided in two bytes.  Worth also on the ILO agenda in a U8?

  The VI are:

• By the way the table of Clusters with binary strings via adapter LabVIEW

  I need to go through LabVIEW adapter table clusters containing binary strings.
  These data will be subsequently stored in the MySQL database.

  I need to force the option "Binary string" for the ValBinary element, even if my output array is empty.

  Is this possible?

  Used versions: TestStand 4.2.1 + LabVIEW 8.6.1

  Attached file: valbinary2.vi containing the clusters of test output array.

  Howdy Jean-Louis,

  My apologies, I'm not quite your question. You're right that LabVIEW does not know that a string is a binary star strong; LabVIEW, chain stores in a format of Pascal, looks like all the strands in the same way. Because TestStand stores strings in the C type format, on the other hand, the null (0x00) characters can be confusing when interpreting strings in TestStand as you learned to understand. That is of course why TestStand offers the feature to interpret strings as binary strings.

  As Sylvie refers to his post, to illustrate his point I created within TestSTand an array of the same type of data customized to store past out of your valbinary.vi of test data. Test patterns, I also edited the outputsome constant values to the cluster VI. (See the following screenshot). Note that the last string (named ValBinary) in the cluster contains a hexadecimal string with a null character that is inserted as the 3rd on-screen character (before the actual end of the string).

  

  Here is a screenshot of the created sequence file that calls the VI and then displays the number of items in the table from the VI to the user.  Note that the Locals.MyTestData table is empty before the execution of the sequence.

  

  Finally, as the execution of the sequence, I opened the Variables pane to view the contents of the Locals.MyTestData table. Here, I have confirmed that the "binary" string of LV was successfully passed in and stored by TestStand.

  

  Finally, the popup message in the second step of the sequence shows indeed a message indicating there were two elements in Locals.MyTestData.

  This sequence has been able to run successfully even without manually specifying a size of Locals.MyTestData beforehand. TestStand dynamically allocated the necessary elements to store the results of test valbinary.vi.

• Is it possible to an array of Boolean function number in a case without the table of Boolean structure?

  Hi guys! In my program, my "robot" (lego mindstorms EV3) has essentially read a code bar and do different things according to the codes bar, he reads and so I have an array of Boolean, and basically I need compare to the other Boolean tables. First of all, I used the "Boolean chart at number" function and then just put it in a structure of the case, but it turns out that the Boolean value to number function is not compatible with my Lego EV3 brick, so I have to find another way to do this. Any ideas?

  Help is appreciated! If you have any questions or if my question is confusing, just ask!

  Thank you.

  
  

• divide table of Boolean

  Hi Sir, I want to ask how to divide an array of Boolean 1 d. for example, I want to put the first 32 bits in column 1, then the 2nd column to and so on... I just want to have a table 2D-32 bits-per-cell... Thank you

  Here is the code of remodel simpler that buffers the last line if necessary.

  

  If you can ensure that the size is divisible by 32, or if you want to ignore the incomplete lines, just wire the 'QI' output directly to the larger size of entry and take additional math.

  If you subsequently want to process 32 elements at the same time, remodeling in 32 lines is much more convenient, for example using autoindexing in a loop FOR, a line of treatment at the same time. Of course, if you want the columns instead, convert after that remodeling as already mentioned.

• Digital table of Boolean

  Hi all

  I'm working on a program where I can input an array of nXy of enumerator that has 3 numerical values of 0,1,2. 0,1,2 values correspond to 3 cases of boolean values constant. Digital and its corresponding Boolean values are given below:

  Numerical value: 0, Boolean values: true, False

  Numerical value: 1: Boolean values: True, False

  Numerical value: 2: Boolean values: True, True.

  So my table values nXy digital hwould turn into nX 2y array of Boolean values with 2 Boolean values corresponding to each digital item in the array. The image shows the transformation that I'm doing.

  To make this work, I took digital and added table 2 loops (one per line) and one for the column of and checked each element of the array to 3 cases. 0,1,2. in each case, I have the Boolean constants corresponding to the case. Given that the nth element of the digital array will lead to Boolean values corresponding to (2 * n) + 1 elements of the array,(2*n) I have a program for that also.

  However, when I released the results, it does not come out properly and I don't know where the logic is wrong. If anyone can help me with this, it will be great.

• A special selection of the table of Boolean

  I use Labview to prepare to use with AB CompactLogix PLC HMI. The problem for me is that I cannot select a bit special (for example to connect with a button, TRUE/FALSE) in an array of Boolean. What I can do is get a particular tag data (integer type Double) plc using OPC and convert these data into array of Boolean. The table can be represented by a series of 32 buttons (I use a card of entry type 32 PLC input fields). But I want to access only the bit 4 of table boolean and toggle an LED based on its output. How to do this? Help, please!

  Leave the data type as a U32 and use the following code:

  

  1 must be of type U32.

  That should do it.

  Play with this idea, also explore GOLD and XOR actions on U32.

• Effective Int32 table in table of Boolean for table Int16

  Have a wide range of Int32 (~ 500 000 elements).

  Each Int32 must be analyzed in two Int16 tables: table 1 the first 12 bits of the Int32, Array 2 is the second 12 bits of the Int32.

  The method I use (see table) works fine but it takes a long time to run (on a relatively slow processor, embedded).

  Does anyone have an idea how to make it run faster?

  Boolean operations on numbers using seems to be quite a bit faster: 42 ms vs ms 280 for 1000000 point tables.  See the image below.

  Also, when I duplicated the code on the image I don't have results you described in your post.  Please post images as .png files.  They can be shipped rigtht in depth with the Insert/edit image button (it looks like a tree).
