• 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.

  Thanks to you all.

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

• 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!

• 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.

• 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?

• 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).

• How to create a grid with the tables and Boolean values?

  As part of a larger project, I'm trying to create a Subvi, which will allow me to spend a "cursor" in a 3 x 3 matrix.

  It should be 2 Boolean inputs, one for move them down in the table and the other to move them to the right. Once reached the edge of the table, the "cursor" will start back at the beginning.

  I have a vague idea of a table to 2 dimensions with LED. Once 'down' has been selected, the corresponding light to (0,0), light (0.1). Goes the same for the button 'right '. When 'down' is pressed (0.2), the LED should turn off, and LED (0,0) must light up.

  I'm sure it has something to do with the initialization of the tables, but I can't seem to find the right way to do it.

  Any help is much appreciated. Thank you!

  Your array is always empty.  Look at the detailed help for the function page replace table subset.  He says that the function has no effect if the specified index refers to a location outside the table.

  What you see on the Panel is only a view and has nothing to do with what is in the table.

• More on my table of full scan question...

  Ok. Apology. start one new thread, like other a receipt very complicated... If anyone can help Id be very grateful, because this results in a significant performance problem...

  XE 11.2

  Re this query:

  Select ENTITY_BUDGET_CAT,

  Sum (actual) real by

  de)

  Select Br ENTITY_BUDGET_CAT_ID as ENTITY_BUDGET_CAT,

  sum (br. BRI_CREDIT) under the real name

  from: br bri_recon

  )

  where ENTITY_BUDGET_CAT = (SELECT "EBC". (' ' ID ' FROM 'ENTITY_BUDGET_CAT' "EBC" WHERE 'ENTITY_ID' = 55)

  ENTITY_BUDGET_CAT group

  The query results in a table full of BRI_RECON scan, even if there is an index on BR. ENTITY_BUDGET_CAT_ID... If I put the where conditition on the inner circle question it works fine.

  The void, select retrieve entity_budget_cat on where clause returns a single value.

  If I replace the subselect statement to get the entity_budget_cat with a literal value, it uses the index on ENTITY_BUDGET_CAT and is much faster with a much lower cost.

  If I remove the sum (actual) external and just retrieve the value and no group, it also uses a sweep of indexes on the inner query on BRI_RECON.

  I need instruction in this format because its share actually well expand with unions comprising the sum of 4 tables, then later adds the value of the outer query to retrieve a single value by group of... The docs say that the filter must be passed to any SQL internally, but everything Ive tried to change the query, but leave the internal SQL without a where clause clause and apply it on the outer query. (as I would a view) translates into a full table scan.

  Here is a simple example of the view I have as an example of how the larger view needs to look for tables of the amount and return a single sum by group...

  Create union_sum_view like)

  Select sum (a) as a 'b' b

  de)

  Select nvl (sum (2), 0) as a 'b' of the double

  Union of all the

  Select nvl (sum (2), 0) as a 'b' of the double

  )

  Group by 'b '.

  )

  Select * from union_sum_view where b = (select "b" double)

  Ive tried to put a hint about it, and it doesn't seem to make a difference...

  Ive looked full statistics on the diagram too...

  So my question is: what is causing the full table scan (which is clearly much less effective). And given that I need to build a view in this way, how can I change to use an index in this format, or what I do to make it work...   All variants and the traces are below...

  If I replace the subselect statement to get the entity_budget_cat with a literal value, it uses the index on ENTITY_BUDGET_CAT and is much faster with a much lower cost.

  Because the query runs faster when you use literal is because Oracle merges internal queries and views, so that it looks to below.

  Select Br ENTITY_BUDGET_CAT_ID as ENTITY_BUDGET_CAT

  sum (br. BRI_CREDIT) under the real name

  from: br bri_recon

  where br. ENTITY_BUDGET_CAT_ID =

  Group of BR. ENTITY_BUDGET_CAT_ID

  However when a subquery is used, as in the column ENTITY_BUDGET_CAT - the subquery must be run before the outer query can send more data, so that the outer query to only return results that match records based on the subquery.

• How can single checkbox can be selected in the table with Boolean checkboxes?

  I have a table editable ADF where an attribute is a Boolean checkbox... and stores the value with Y or N.
  
  Is there a way where the single checkbox must be selected at time of posting?
  
  For example, in the case its a table of responses to a choice unique to an application of Questionnaire, Question by adding new responses to the table..., the user inserts 3 rows (answers)... then the Boolean checkbox for only one of these 3 rows can be verified.
  
  Thank you
  DJ

  Since you have an attribute that has the "Y" or "n" for each line.
  When the user selects a line, you must deselect the other lines using the value change listener pro-grammatically.
  If the number of rows is large, it could be performance intensive.
