• dynamic double bit data conversion

  It could be very simple, but I was confused. I have current data and average data as in code. I want to build the table using these data, save them on my hard drive and open in word with header (current and average)

  Problems:

  I have data from two sources in lead generation and versions table as shown entry table to write on the worksheet vi. I get the error source is dynamic and double sink is a bit. It is the most difficult part of my life to find out what range of conversion to use.

  When I run the vi (lets assume the good range of conversion is connected and there is no conversion error) pops up the dialog for path that comes up constantly on dialog

  Ideally I want appears on the screen when I press on would go so that I can browse location to save the file, and once the path is specified vi works continuously and the data is written to the worksheet while vi is running.

  Thanks a lot for reading and help

  See you soon

  Welcome to the evil world of dynamic data. What you really want to use is the merging of signals feature. When you do this a dynamic data conversion will be automatically added between the signals to merge and writing on a spreadsheet file.

  You can consider using writing to the file position as directly accepts dynamic data.

  With respect to the path, use a shift register.

• From dynamic data to string

  Hello

  I would like to convert my dynamic data (4 channels and time) to sink chain (I use UDP write).

  I tried to build a table and then use Nnmber to the fractional frequency range, but I can't wire both, because it's 1 d array of string.

• problem about dynamic data to the conversion of table 1 d

  Hi all

  I have problem with the conversion between dynamic data and table 1 d.

  I wrote a simple VI to show the problem, as the attached picture. Convert dynamic data in table 1 d, and then return to the dynamics of data, I use 3 tables of waveform display data in 3 different places, but only 'force contact 2' the graph looks normal and the 2 other cards are strange data shows. In addition, the probe indicates that data are all just before going to the charts. What is wrong with him?

  Can someone help me?

  When you convert a table, you lose your calendar information.  You need to convert a waveform and manipulate waveform data.  Use a Structure of elements in Place with waveform components to manipulate waveform data.

  Hello world

  I try to just do simulated flashing of the LED with a square wave. It has been 3 hours I'm looking why the does'nt of convertion of dynamic data that is updated at each iteration (it seems that the problems).

  I tried with all the options of the object to "convert", but I could not (I'm desperate)

  in the attached .vi, I chose "the most recent value.

  could have a peek at my .vi?

• Date conversion madness! String to date and vice versa

  Hello, I am working on an application targeting the OS version 4.5.x. I read a lot of messages and the links on this topic and can't seem to make the correct code.

  OK, here's the problem. I ask a timestamp date string to a server. The timestamp is the local time on the server (IS / PST etc.) and not GMT.

  My application must take time and subtract a number of days ranging from 1 day to 1 month. to get a "start" date The application must then provide the start and end date in a string format that it understands. Seems simple isn't?

  Here's the catch, however the time stamps should NOT be changed by the local what is using the device. For example, a device in Italy can contact the server located in Ottawa and ask a timestamp, the calculations shouldn't care about DST or time zone. Just take the supplied date and subtract a fixed number of days from her. Nothing more or less. This proved incredibly hard to do. first the HttpDateParser.parse (ServerTimeStamp) will be the subject of Date GMT and my problem is back to the zone specified in ServerTimeStamp.

  Thanks for any help in advance.

  My method

  public String getDAFIXMLRange (String ServerTimeStamp) {}
  String szRange;
  First analyze the incoming date and record them at the time of the last election.
  Day DAFIEndDate = new Date (HttpDateParser.parse (ServerTimeStamp));
  m_lLastPollTime = DAFIEndDate.getTime ();
          
  define the offset. Pre-programmed for simplification.
  lOffsetNumberOfSeconds long = 2 * 24 * 60 * 60;
          
        
  Calculate the start date by subtracting the offset. Multiply by 1000 to convert to milliseconds!
  Date DAFIStartDate = new Date (DAFIEndDate.getTime () - (lOffsetNumberOfSeconds * 1000));

  !!!!!!!!!!!!! HOW the DATEFORMAT OBJECT is used to get the output format ' yyyy-MM-dd' you HH: mm: "without the marker of time zone. The server knows that it is local to it. !!!!!!!!!!

  Now format the objects date as a string that includes the XML server.
  DateFormat DafiDateFormat = DateFormat.getInstance (); ' YYYY-MM-dd' you HH.

  !!!!!!!!!!!!!! THIS IS THE PART I'M CONFUSED on, with the HELP of zone to create the good date. !!!
  Time zone tz = TimeZone.getTimeZone ("IS");
  int adjEST = tz.getRawOffset ();

  Convert 'em in string format.
  String szDAFIStart = DafiDateFormat.format (DAFIStartDate);
  String szDAFIEnd = DafiDateFormat.format (DAFIEndDate);

  Replace the date calculated in the end segment ranges date XML.
  szRange = statItems.replaceAll (XML_DATERANGE, "TAGSTARTTIME", szDAFIStart);
  szRange = statItems.replaceAll (szRange, "TAGENDTIME", szDAFIEnd);
  Return szRange;
  }

  Hello

  Yes would be better if the server could provide you date to the GMT time zone, or date as a long.

  But if you can't ask the case on the server, one way might be to manually parse your string and create a new date of parameter values in a calendar, something like this

  Calendar cal = Calendar.GetInstance ();

  Cal.Set (Calendar.DAY_OF_MONTH, date)

  Cal.Set (Calendar.MONTH, month-1)

  Cal.Set (Calendar.YEAR, year);

  ' set the new time with the values, you must cal.setTime (cal.getTime ()-,...);

  and then put the date with SimpleDateFormat.

  I think that this could be a solution if you know the format string you recived that date and it won't change.

  I'm not sure but maybe it could be a solution.

  Kind regards

• Dynamic Data in Array - time values

  Hello

  It's me again.

  I have read the lines of a lvm-file and save it in a table by using dynamic data type conversion. The first column, I have in the file is at the same time; I wish I had the time as the first column of the table too, but I couldn't find how to do this. I found this thread , but I think that I can not use this way because I read the unique lines and treat...

  The attached picture should show how I mean this. So, is it possible to get the time (from file) as a column in the table?

  Thank you

  Hello

  I'm afraid, because most of us never use screws express, you can have a hard time finding someone willing to get acquainted with them to analyze your code.

  My advice is to get rid of the express vi (not just because you'll get more responses ).

  Using the palette file I/O, and then something like string from picture to picture the range of string to convert your data into a 2D array can give just the output that you want.

• Medium-sized dynamic data analog input read DAQmx read

  Hi, I'm new to labview. Is there an easy way to index using the dynamics of data returned by a readout DAQmx x samples to calculate a moving average? My thought was to read the analog input for X samples pump with the data in another loop through the data, but I can't quite understand how index using the returned data set to extract the measurement value double returned for each sample.

  Any ideas on that?

  Thank you...

  If you get a type of waveform data, why did you ask on dynamic data? No, of course not would you use the conversion of dynamic data on a waveform.

  If you want only one channel, then your DAQmx Read could be changed to 1Chan NSamp. If your channel list only has one channel, you will get a table 1 d with a single element that can be indexed. To get the average of a waveform use the statistical function with the waveform. You use the average Point by Point, and not the average function that has a table for an entry.

  Make sure you always have context-sensitive help on. You can avoid many of these rookie mistakes simple.

• How can I draw dynamic data that I get a hardware DAQ against each other?

  Hi all

  I am trying to acquire voltage and current data of DAQ hardware. My goal is plotted against votlagein current a continuous path. As the votlage is increased at intervals of 1 Volt, every second I want to see how the current. However, this data is dynamic and I need help find how to draw in a single chart. Any thoughts on how to draw the two different dynamic data against each other in the same graph?

  You help will be very appreciated.

  Thank you

  If I understand what you're saying, looks like you want to have the update of XY graph with each new data point (or points) acquired, but also choose to keep the previous data on the XY graph.  If that's what you're after, I build on my previous example.  For the method of use of the express VI build XY graph, you can simply double click on it and uncheck the "erase data on each call.  For the other method of construction of the dashboard cluster, you will need to add a few records to offset to maintain the previous itterations table values.  Here's the updated image:

  

• Plot multiple charts XY (dynamic data type)

• Producer / consumer set loop of dynamic data item type

  Hey all,.

  I do a simple exercise of producer / consumer in a loop. In my loop of producer I audio Aqcuerir and in the loop of consumer I'm projecting on a chart

  Everything works as I had in mind, the only thing that bothers me is the way that I had to set the type of the element to the block "Get the tail" at the beginning.

  I knew no better way to get the kind of data that I used to just take an another "acquire its" Express VI and which hang. But that may not be the only way to get there, right?

  Note: I know that I might not need to use a producer / consumer design tend to do, but I need to get hold of technology for school work so I came with this exercise just to get a hang of it.

  Thanks in advance,

  Al.

  Al,

  You just need to feed the correct data type in this entry, which you did by getting the output of a second acquire its Express VI.

  You can also use the "Convert to Dynamic Data" function to do this.  When you drop to the bottom of the function, you will be asked to give the input type.  Tests I've done, it seems not to matter, but for example if you chose the entry to a single scalar type, you need to feed a digital constant (change to double type) in the entrance and use the output of dynamic data such as line item data.

  I don't like the dynamic data type because it is not very clear as to what it is.  Another thing you could do would be to use the "Convert from Dynamic Data" function to change the output of the VI of its acquisition to a different data type for more or less to avoid the original problem all together.

• Table 1 d of dynamic data index

  Hello.

  I have 2 son of dynamic data. Basically, I want to access each item of two, with a single function (module) in a moment.

  I use table to build, and with a probe, I see for wire 1 (items: x 1, y1, z1,...) and for the 2 wire (items: x 2, y2, z2,...).

  Now, I want to use a function (module) good enough to choose for example to y2 2 and wire1 z1.

  Thank you.

  Hei, I got it!

  I used the table of generation 3 and 1 index table 2D. Innitialy, I put merger signals instead of build table, so I was stuck there.

  Thank you for being around.

• Track of multiple graphs on a single diagram of waveform with dynamic data types

  I'm putting multiple charts on a single diagram of waveform and data contract error. I was wondering if it has something to do with the fact that the dynamic data is used (I have had no problem with other types of data in the past). Does anyone know how to fix this? I have attached the following .VI. There will be a lot of. Live on the bottom which does not load, but they are not related to this problem.

  Thank you!

  Brian

  I don't know what you're doing now, but a part of your origianl code is simply ridiculous. Your DAQ assistant takes a single point. You convert that into an array. If you had converted into a scalar value (which is) first place, your graphics update would have been fine.

  If you want to remove the DAQ Assistant, and then select generate DAQmx code. You'll be a little more closely, but it seems that it generates a NChan DAQmx Read 1Samp instead of a 1Chan 1Samp DAQmx read.

• Set the attributes for dynamic data waveform t0 zeros?

  HI -.

  A beginner to labview here, so please be nice ;-)

  I have a simple setup with mainly express screws where I follow the steps below in a while loop

  (1) collect signals with the DAQ Assistant, that generates dynamic data. It is the collection of samples of N

  (2) changing the attributes of the dynamic data using the express VI 'Set the Dynamic Data attributes'

  (3) storing dynamic data revised to a file by using the writing to the file of the measurement.

  The problem I was see is that whenever I have insert the express VI 'Set the Dynamic Data attributes' in the data flow, I find myself with a file where synchronization of the signal (i.e., the waveform t0) was cancelled. This seems to happen any dynamic data attributes, I edit. For example, even if I try to set the name of signal I find myself with out having a nulled-out t0

  FYI, I'm using Labview 2009 9.0f3, 32-bit

  I have attached a code simplified showing what looks like a bug to me. Any help would be appreciated!

  It looks like a bug to me as well. Also, unlike other screw Express, you do a right click on it and select open the face before seeing what the problem is. It's pretty simple to find a work around. I converted to a waveform, has obtained the t0 and handed that back as the timestamp for the signal of slected.
