Analysis of the variable format string

• The analysis of the Variables of e/s channel properties

  I have a situation in which I would like to configure the Daq on a cRIO since an interface of configuration on a Windows host. In particular, I would like to get IO addresses Variable for all analytical engine channels configured on the cRIO. The Setup program runs on the Windows host and impossible to deploy any demon on the RT which could question the material. He needs run as if the cRIO is not present.

  The configuration program is part of the same project as the cRIO, so my thought was to analyse the project to find corresponding topics. Here's a post that does something very similar:

  https://decibel.NI.com/content/docs/doc-16630

  However, this has several problems. This example was written in 2011. I am using 2015. Apparently, the properties have changed since then. Children' find' (it is no longer named "children []") does not give me the chassis on my 9068 reference. Instead, I could use the property "Items Owned []", which gives a bunch of things, and then I search the TypeString of these things until I have find one that is "Chassis". Fair enough. Then the ref chassis gives me the Modules and the Modules of give me the channels. Seems pretty good. But all I get are the names of channel. I can't find all the properties that define the type of module or the direction of IO. For example, I would like to know if a variable is a Boolean or real, and if it is a path of entry or exit. You can deduct that the names 'standards', if the project has not been changed to allow giving them a meaningful name to create or. But it looks like there should be a way to find these properties directly.

  Any ideas?

  TIA,

  I think that the analysis of the project tree is a quite fragile strategy that you should know already. AFAIK the OR sanctioned for this sort of thing for a few years now is to use the API of the System Configuration. Yes, it's a pretty involved API and need you a little time to learn how to get the specific information you are interested in. Fortunately there are some examples that you can use to start with.

• How to jump 3 characters when use "scanf chain" by the parameter "format string"?

  Hi, I want to read a number 123 in the chain like that 'sfg123' 'fgd123' 'ghj123 '.

  I know that I can use 3 '%s' to jump 3 characters, but it will add an output to 'scanf string.

  So, how use "format parameter string ' not only to jump 3 characters, but also add no output to"string scanf.

  Hi Chenyin,

  Try this VI...

  I think so... That's what you expect...

  Hi all
  
  I have the column in the table and the column will be the varchar2 data type. I need the value of the specific model column.

• Why not the type of the variable is a string?

  Hi, I need your help. \(´o `)/

  When I'm "DropDownList.items", the type of the variable dose not become the 'string. '
  Why?

  ------------------------------------------------------------------------------------------ ----------------------------------------
  var ddList = new Array();
  ddList = ["adobe", "DSP", "Japan"]; any value string table

  / * Create window * /.

  var = DLG

  "dialogue {text:"Interface of Script", limits: [200,200,460,350],"+}.

  "panel0:Panel {limits: [10,10,240,140], text:", properties: {borderStyle: "engraved", su1PanelCoordinates:true}, '+}.

  var win = new window (dlg, "click on the ok button!");

  for (var i = 0; i < ddList.length; i ++) {}

  Win.panel0.ddownlist1.Add ("Item", ddList [i]);   Add items to doropdownlist.

  }

  Win.panel0.ddownlist1.selection = 0;

  Win.panel0.button1.onclick = function() {}

  var ddownlistItems = win.panel0.ddownlist1.items;

  for (var i = 0; i < ddownlistItems.length; i ++) {}

  / * If when 'isNaN' command was returned to 'true', while the type of the variable is "string", if it was referred to 'false', so no 'chain '.  *****/

  Alert ("ddownlistItems [" i + "] plus" + IsNaN (ddownlistItems [i]));

  }

  }

  Win.Show ();

  ------------------------------------------------------------------------------------------ ----------------------------------------

  I tried this script, "alert" has been returned "ddownlistItems [0] = false '.

  but the setting of the components dropdownlist used table of "channels".

  Why not the type of the variable is a string?

  Thank you.

  Because you do not test the chain only the index.

  try...

  Alert (ddownlistItems [i] + "=" + isNaN (ddownlistItems [i] .text));

• The analysis of the non-numeric characters in a string

  Hello

  I am communicating a robot to LabVIEW (2013) via TCP/IP and sockets. The robot is the server, and LV is the customer.

  I start with the target data in this format (in a string):

  "[0 ~ 100 ~ 0] ~ [0.96593 ~-0.25882 ~ 0 ~ 0] ~ [1 ~ 0 ~ 0 ~ 0] ~ [150 ~ 50]."

  [X, Y, Z], [Q1, Q2, Q3, Q4], [C1, C4, C6, Cx], [TCPVel, OrientVel] except replacement ',' (comma) with a ' ~ ' (tilde) because I load the target data in a spreadsheet which is a comma-delimited file.

  In LV, I take this string, the analysis of the chain and split individual items. I then pulled the singular elements as unique, 32-bit of real numbers. I take each one and convert them individually to a string, concatenate them and send them to the robot. The robot decompresses these raw bytes individually and converts them to a target of robot (position in space).

  I train (BT) check if the user has sent a bad character (non-digital) in the target data. Example of this is:

  [- 50 ~-150 ~ 0] ~ [0.96593 ~-0 ] [B2has5D882 ~ 0 ~ 0] ~ [1 ~-1 ~ 0 ~ 0] ~ [150 ~ 50]

  Now in BT, when I'm scanning the chain, these bad character becomes the entire element to zero and everything else then to zero as well. See attachment for example screen similar.

  My question is, my VI, I can analyze all non-numeric characters (that are inside the parentheses and characters that are NOT a ' ~ ' (tilde))? In this way, I can always get this item numbers and do not have this element or other items turn to zero?

  Thanks in advance for any help!

  Sorry for the question of the test

• ANALYSIS OF the CHAIN fails with empty quoted strings

  I'm scanning a long text with the STRING SCAN line.

  

  "[My problem in the first place of this part: " [^] "]"

  The string I'm scanning a quotes in it - I want to extract the string in quotes as a single item.

  I can't use %s because the string can have spaces that it contains.

  The format string works fine except if the quoted string is empty ("").

  "[I interpret " [^] "]" a number of things that are not a QUOTE, QUOTE, QUOTES.

  Apparently, 'any number' does not include zero, as it fails (error 85: data not matching format) when the quotes are empty.

  What Miss me?

  This confusion arises as well in RegExes, but you hit on the answer: in the Simpsons "Zero is one percent", but in the analysis of String Nothing is not something.  You asked to match something that's not a quote, and there is nothing here that is not a quote, so it complains.

  In this situation if I really wanted to keep the convenience of analysis of string I would generally use Search & Replace to replace "" with "\00" before scan and then process a string that only contains null as empty.

• How to create a group/list of the variables in the box for display in the text field, in the format in annex

  I need to identify a series of variables single-response checkbox and display links selected (as a group) in a text field in an annex (comma, space) format. Last week, you provided a small script for a similar requirement by using the list box (multiple response) variables. This time, I need to know how to identify the variables of the box officially and, presumably, use a similar script to display the results in a comma, space format.

  You've been a great help.

  Thank you

  Here's the script for this situation. It assumes there are ten boxes named cb1, cb1, cb2,... cb10.

  // Custom Calculate script for text field
  (function () {
  
      // Initialize the string
      var v, s = "";
  
      // Loop through the check boxes to build up a string
      for (var i = 1; i < 11; i++) {
  
          // Get the value of the current check box
          v = getField("cb" + i).value;
  
          if (v !== "Off") {
              if (s) s += ", ";  // Add a comma and a space if needed
              s += v;  // Add the selected value
          }
      }
  
      // Set this field value to the string
      event.value = s;
  
  })();
  

  You will have to change the name of the field and start/end numbers to match your form.

  This is the correct format. If it does not work for you then you need to give more information than what is happening, how fill you your Init blocks etc.

• Is there a way to parse a string containing % (percentage symbols) using the function 'analysis of the chain?

  I am communication in series with a mirror device and the syntax of the input string contains this text: "% hr ="

  I was not able to find a way to say to the function that the percentage here is not a format specifier. Is it possible, or should I just try to use a different function?

  Thank you.

  Use %% in your format string for what he knows to use the percent literally.  So % RH = %f

  

  EDIT: Darin has one here in front of me.  It seems to be-% and % both work.

• digital conversion (in the format of the time) to string

  Hello

  I have a digital control (at the time format) in which I hours: minutes: seconds and I want to convert it to a string. The problem is that the number of hours is incremented by one, and if I insert a number of hours exceeds 24 the string is not displayed correctly.

  What should I do to make this work?

  Thank you

  You use a function that should be a numeric value that is based on the UTC clock and then convert it to a clock display based on your current time zone.  My guess is that you are in GMT + 1, which is why you see an hour added to it.

  You must use the Format function in the string for this with appropriate time for the format codes codes.    %t is relative time.  It takes number you enter and turns it into hours, minutes, and seconds, rather than trying to create a view of time for her.  This is why your code cannot ride beyond 24 hours.   (There is no 25 hours on a clock face).

  

• Analysis of the error in normal mode string

  Hi all

  Suddenly, my analysis of the chain has stopped working and started giving me this error. The read string ends up being something like 2.86E - 4 or similar. When I run mode highlighted everything works fine and it interprets the number very well but when he's not in highlight mode it returns an error. Not sure why since it is just a number to convert. Any help? I have attached the error and the highlight mode version. Thank you!

  First guess: synchronization problem. Especially since you said it works in highlight mode. Specifically, when you run culminating point mode you expect probably not long enough before trying to read, and the loop will immediately detect any byte on serial port. This delay function there will not guarantee a delay of 1 second between writing and reading. There is no dependence on the data - a rookie mistake. Use an image sequence or time to late VI to have clusters of error wiring through establishing the data dependence.

• The analysis of the data of a string of series

  Alert LabVIEW Express 7

  Sorry, all I have to work with and there is no budget at the moment to upgrade.

  Hello, I am in phase 1 (data transfer reliable to labview) 24/7 of my small Miettinen, who is to display and record data environmental Lab 24/7 our Fisher 02-403 digital barometer that has a serial port. In fact, it came with the software, but no one here seems to like use it so I'll try to find something more intuitive. I can't find any info at all about I/O with this device, so I'm reverse engineering. I'm sure that you cannot write anything to this device only read.

  I started with the connection of the device and the interface with NOR measure and automation and received the following string: P,43,1019,44,31,01,0023.0\r\n.

  I tried to use the Labview 7 Express e/s Companion Instrument, selected 1 COMM, changed the timeout to 5000 (trial and error), added a step reading and analysis, ran and received the following string: P, 43,0999, 44,41, 01,0018.0, XX. After well guess, I determined that the values I have in bold change with the environment and the other 3 are always the same idea 9no what they represent). Alphabetical 1 in bold represents the tendency of climate S sunny = P = C sunny cloudy = etc., the value 2 is the atmospheric pressure in hPa, the 3rd is % relative humidity and the last is the temperature in Deg. C.

  At first, I tried to create simply chips for data I want and operation loop the wizard of e/s in awhile, but often error messages obtained suggesting that I need to define all the tokens in the string. I did it and it worked, then I opened the front panel to access the underlying schemas whence I came with the attached VI. I left this race for more than 24 hours, no error, seems good.

  My question on this forum is, can I simplify this VI losing a part of the analysis of the data that I don't need at this point?

  Please let me know if you can not access this VI maybe I can do a screenshot or something.

  Thank you

  Doug

  Yes, it can be simplified to just a bit.

  

  Since you are new to LabVIEW, you can start with the basic tutorial.

• Unit to the Format string

  Hi all

  If a control already has a unit, and move us to a format based on the string, its does not display is not the same exact unit. For example, under control has 'g' unit, while the format string has unit "kg".

  

  1. Is it possible to do the format to a string take the exact unit specified in the control?
  2. Is there a way to delete unit in the format based on the string, even if the digital order entry has a specified unit?

  Attachment VI to 2010.

  Thank you

  Knockaert

  Not automatically, no. The problem is that the designation of the unit in effects only control how data is displayed in a particular control. When wire you a value with units in a format to the node of the chain, it will express the value of the base unit for the wire.

  Mike.
