• How to find valid cases in the truth table?

  Hello

  I am using a truth table to select the next case in my state machine. The number of possible cases is 256 with a set of 8 input of Boolean values. The following is a generic example.

  I often do.  Take each of your eight Boolean and consolidate them in a table, convert the table number and select your case on that based on the number.  Thus, if the first fifth suite and boolean (from above) are true, you have 25 case (10011000 = 25).  You can have a case manage multiple values, separate them with a comma in the selector.  It will make you famous.

  Solomon Yakobson says:
  Well, NULL means value is unknown.

  Distinguishing on this specific statement (get all semantic on you ;-)) - NULL is not a value in itself.) That's why we can use mathematical operators on it, because there is no value to operate on. And that's what means NULL. No unknown value, but no value.

  Think about a column in Oracle as having two possible States. A value or no value.

  NULL is therefore a variable or a column "+ State +" descriptor and not some kind of value that is assigned to it.

• Summary of complex scenario (counties)

  Hi all

  Looking for inspiration and ideas with this little teaser

  I'm trying to find a common approach to the production of four counts (A, B, C and D) indicated in lines 1 to 5 below. This function of a table that contains about 4 000 entries.

  

  In affect, I try to summarize the different permutations in the classifications of four cells show in the image above, using a common approach. I might add a column for each company and use wild-card account, but I'd rather keep the table of (imported) origin of tact - I know that I could build a table of distinct society in another piece of work, but there must be a smarter way to achieve this.

  The legend below presents an overview of how the data looks like with different options (style truth table). The reference column contains a master list starting with RE - unique references.

  NC and P columns contain company names. There are two additional columns and the television that contain one or more numbers starting with- and TV - respectively.

  

  The idea is to check that the RE has a link to references or TV in the respective columns when there is a company name in the naming context and / column P

  There are a number of scenarios based on conditional counts in two columns: following NC and P with the possible permutations:

  Swap 1: Where there is a company name in the column "NC" count the number of:

  • RE links to OF
  • RE TV links
  • RE links to OF and TV
  • RE completely unrelated
  • More than one company with no link

  Swap 2: Where there is a company name in the column 'P' count the number of:

  • RE links to OF
  • RE TV links
  • RE links to OF and TV
  • RE completely unrelated
  • More than one company with no link

  Switch 3: When there is an entry in the column "NC" both "P":

  • RE links to OF
  • RE TV links
  • RE links to OF and TV
  • RE completely unrelated
  • More than one company with no link

  At this point, my head began to ache - would be very grateful and ideas on how this could be done.

  Thanks in advance

  If I understand correctly, you can compile your different counts using COUNTIF with the * wildcard, something like this:

  

  For more convenience in formulas to set up your data in a table and your account in another.

  Here are the formulas in the table 'Account':

  B2:	= COUNTIFS(Data::$B,"*RE*",Data::C,"<>"&"",Data::$F,"*DE*")
  C2:	= COUNTIFS(Data::$B,"*RE*",Data::D,"<>"&"",Data::$F,"*DE*")
  D2:	= SUM(B2:C2)
  B3:	= COUNTIFS(Data::$B,"*RE*",Data::C,"<>"&"",Data::$G,"*TV*")
  C3:	= COUNTIFS(Data::$B,"*RE*",Data::D,"<>"&"",Data::$G,"*TV*")
  D3:	= SUM(B3:C3)
  B4:	= COUNTIFS(Data::$B,"*RE*",Data::C,"<>"&"",Data::$F,"*DE*",Data::$G,"*TV*")
  C4:	= COUNTIFS(Data::$B,"*RE*",Data::D,"<>"&"",Data::$F,"*DE*",Data::$G,"*TV*")
  D4:	= SUM(B4:C4)
  B5:	= COUNTIFS(Data::$B,"*RE*",Data::C,"<>"&"",Data::$F,"",Data::$G,"")
  C5:	= COUNTIFS(Data::$B,"*RE*",Data::D,"<>"&"",Data::$F,"",Data::$G,"")
  D5:	= SUM(B5:C5)

  You can learn more about COUNTIF here (you can also access it via help > formulas & functions help menu.)

  For more information on the search for wildcards of 'wild' in help > formulas & functions help

  The function works with pairs of columns-condition, where you add a reference to a beach (usually a column because it's more convenient) and then apply a 'condition' against it, indeed the application of several filters.

  You can add pairs more than necessary.

• Suggestion to turn this into a business structure

  This is an excerpt from an existing code that we were committed to change/clean. I have to assume there is some way I can reduce this to have only a business, maybe with a not - or not - or structure. Or maybe I'm overthinking cela. Basically I confusion to keep me in the code relatively simple when thinking about Boolean values compared. Any help is appreciated.

  

  This seems to be just a NAND, pure and simple.

  I came with the truth table was:

  old new write to the world

  0      0         1 (< is="" false,="" new="" is="">

  0      1         1 (< is="">

  1      0         1 (< is="" false,="" new="" is="">

  1      1         0 (< is="" false,="" new="" is="">

• While/loop and reset the value i in time loop

  Hello!

  I have a question about the use of while/loop for.

  I read the data of 5 devices.

  Starting with the 0 position when I = 0, I read the data at position 0.

  And when I click on NextPosition, then I = 1 and stop when I = 5.

  But in the meantime, if I want to break the system of position 3 for now. I click on the BREAK.

  I chose the position back to 0, it will go to this post.

  But if I click on NextPosition, the value is always my 0 and not 1, which is the next position upward.

  In addition, whenever I click NextPosition, it will count up to i = 5 and to stop the program.

  Is there a way I can address the issue?

  

  Thanks for trying!

  I don't know what your needs are, so I guess you want to keep hitting the same device until you press the button of the next device and you want to be able to specify that one then.

  In the attached code, I changed your mechanical action of the pause button and renamed position Reset.

  I also changed the code suchthat conditionally, we increment the device number (only when the next button is hit).

  I have alos moved local so that us do not draft times and put it in the case of the rest the structure so it is written or read but not both.

  If this does not meet your needs;

  1) look in bulb mode and see where I went wrong

  (2) If you are unable to set up a truth table of all combinations buttn and doc what steps should occur for each condition.

  Always trying to help,

• What is an xnode object?

  Okay silly question, but what is an xnode object? I saw them mentioned and I know they have something to do with the scripts. The LabVIEW help search gave nothing of what has been very helpful.

  I was playing with these guys a little bit lately and will offer a few thoughts, I won.  XNode is roughly the equivalent of an XControl comics.  It is organized like a normal library, and a .xnode file is basically XML as a file .lvlib.

  XNodes have some of the "capabilities" that you control by writing ability live.  They range from the drawing of the image, to specify the terminals to generate the actual code.  There is a lot of flexibility, you can adapt for wire types, resize nodes horizontally and vertically, to have configuration screens, text fields.  The downside is that there are a lot of luggage, IE. all these screws capacity should be around, so a simple VI with a unique XNode may require dozens of subVIs.  No problem when they come with LV, a bit of a brake to home built ones.

  I've been a promoter of the end regarding XNodes and I'll soon (I hope) to release my XNode assistant on the community.  It deals with the creation of XNodes and add capacity VIs and SubVIs.  It also simplifies the process for most of the core capabilities.  My favorite part is that it eliminates scripting in many cases.  You write a VI model, use my tool to the terminals of the tag on the comic book by clicking on an image and then simply generate a list of rules of XNode wiring lugs on the terminals of the BD.  I also have simple tools to bundle/unbundle inputs/outputs for expandable nodes very popular.

  The old claim was XNodes would be too complex and not the type of the 'customer experience' that LV users want.  I intend to prove them wrong, stay tuned.  Once, they said similar things about scripts...

  In the meantime, let me know if you can make sense of this

• Logic Analyzer

  Not sure how to connect the Logic Analyzer to expand the table of truth. New on EE.

  You placed a logical converter not a Logic Analyzer.  The converter works with circuits containing doors such as AND, NAND etc... it will not work in a circuit with flip flops.

  All the stems pointing to the left of the Analyzer are entered, you can use pins to analyze your circuit.  When you double-click on the instruments, click on the 'Set' button under the area of the clock, set the clock frequency two times your highest frequency.

  Please help me understand this.

  Thank you

  It is important to realize that NULL = 'unknown '.

  Let's dig yet this truth table (sorry John):

  A AND B A AND B

  =====  =====  =======

  FAKE FAKE FAKE

  TRUE FALSE FALSE

  FALSE FALSE TRUE

  TRUE TRUE TRUE

  Now, in your example, we cannot see what is in the a:

  A AND B A AND B

  =====  =====  =======

  ?????  WRONG WRONG

  ?????  WRONG WRONG

  ?????  TRUE FALSE

  ?????  TRUE TRUE

  If B is FALSE (as in your example), it does not matter what the A - the answer is going to be FALSE. If B is TRUE, we cannot say what the answer should be - it could be - is unknown, or NULL.

  You say that you do not have the privileges to try a query yourself, or that you cannot create a table?

  If you cannot run a query, regardless of what query someone messages in response?

  If you can not create tables, then validate your data in a WITH clause.  For an example, see the Forum-FAQ:

  Re: 2. How can I ask a question in the forums?

  However, if you are supposed to be writing queries, then you should really be able to create and populate your own tables to test.

• NOT operator

  Hi everyone, I have a problem with the not operator in oracle.
  
  study the following

   
   WITH data AS
   (
   SELECT 'TAK' cd, 'PL' TYPE FROM dual UNION ALL
   SELECT 'TAK' cd, NULL TYPE FROM dual
   )
  
  
   SELECT * FROM data WHERE NOT (cd = 'TAK' AND TYPE='PL')
   

  the foregoing does not return anything. what I want to do is to exclude all lines containing the cd = TAK and TYPE = PL
  the rest should be display. If the output should be

  CD       TYPE
  ============
  TAK      <NULL VALUE HERE>

  However, the query above is not that. How can I change my request to exclude lines with cd = TAK and TYPE = PL but they appear, one that does not meet this condition as

  Remember, SQL uses 3-value logic.
  Conditions can be TRUE, FALSE, or UNKNOWN. The lines are returned if (and only if) the WHERE clause evaluates to TRUE.
  If a cd or type has the value NULL, but the other variable, that's what the condition tests, then

  WHERE NOT (cd = 'TAK' AND TYPE='PL')
  

  will evaluate to a STRANGER, because
  NULL = x is still UNKNOWN, no matter what x is.
  TRUE AND UNKNOWN is UNKNOWN, and
  NO UNKNOWN is UNKNOWN.

  See truth tables in the manual of the SQL language.
  http://docs.Oracle.com/CD/E11882_01/server.112/e26088/conditions004.htm#sthref1938

  If you want to assimilate NULL cds with something other than "TAK" and assimilate types NULL with something other than "PL", here's a way to do it:

  SELECT     *
  FROM     data
  WHERE     NVL (cd,   'OK') != 'TAK'
  OR     NVL (type, 'OK') != 'PL'
  ;
  

  I find the condition above, easier to understand than the condition below, but they get the same results.

  SELECT     *
  FROM     data
  WHERE     NOT (    NVL (cd,   'OK') = 'TAK'
           AND      NVL (type, 'OK') = 'PL'
           )
  ;
