• When you use a left and right axis, how to choose what issed axis for the value of y GetGraphCursor?

  I use a graph with a left and right axis (2 data sets).  I try to use a slider to select a point in time (x) and the values of y in the two sets of data.  I can't understand how the control, the value that is returned for the value is when you use the GetGraphCursor call.

  GetGraphCursor (panelHandle, PANEL_GRAPH, yourCursorNumber, & x & y)

  Using SetCursorAttribute with the attribute ATTR_CURSOR_YAXIS must be what you are looking for. The online help for this attribute explains wery well:

  Description: Used to change the y-axis which is associated with the bar graph.
  When a graphics cursor is created, the Y axis with which it is associated is determined by the value of ATTR_ACTIVE_YAXIS.  Subsequently, the association can be changed using ATTR_CURSOR_YAXIS.
  The y-axis associate serves as reference for the coordinates of the cursor position in calls to SetGraphCursor and GetGraphCursor.

• Sampling rate higher for the measurement of precision meter

  I have a BNC 6259 M Series DAQ USB. I am currently using the DAQ Assistant to perform simple cash rising measured with the measuring mode single sample on request. I tested my VI with a known square wave with a function generator signal and it clearly lacks a few edges. I think that the solution lies in faster sampling. However, I was not able to understand how to use clocks to set up continuous sampling mode. I tried the forums and I found articles that were close, but not quite exactly the problem I am facing with as (http://forums.ni.com/t5/Digital-I-O/trying-to-use-NI-6251-s-DIO-port-as-input-and-output/m-p/448035#...) or (http://forums.ni.com/t5/Multifunction-DAQ/Using-Counter-of-PCI-6024E-with-Quadrature-Encoder/m-p/984...). Any guidance here would be great.

  In fact, the calendar should not have anything to do with the edges being detected.  Configuration of a sample clock for a county of just edge task allows you to enjoy deterministically in the account register and has no impact on the edges which can be counted.  Also, the analog examples really have nothing to do with what you seem to be asking questions on.

  ... So it leaves the question unanswered as to why you might miss the edges.  Perhaps the following information could shed some light on the question:

  1. it is possible that you do not configure the counter exactly as you think you are.  Can you post the VI you use?  As a point of reference, count digital events shipping example does not use any clock sample timing and just questioned the value of the register count with a software loop, but the meter should not miss all this edge on the input source.  There are examples that are timed by the material available as well, but this is not necessary, unless you need a constant specified dt between your counter samples.  To use the examples of the timed sample, you will need to generate a clock of either another subsystem on the map or use an external clock.

  2. assuming that the configuration of the counter is not the issue, there may be a problem with the method that you use to determine if you are away from the edges.  How do you know that you are away from the edges?  The function generator produces only a finite pulse amount?  You start the meter before start out impulses?

  3. If the two points above do not raise red flags, it seems likely that the meter is registered just not some of the impulses of your FGEN.  Can I assume that the output of the FGEN is 0 - 5V TTL?  What is its frequency and duty cycle?  The maximum external source for the meter on the M-series products: DAQ (like the 6259) is specced at 20 MHz, but this depends on a clean signal with good connections.  At frequencies above it, the bandwidth of the front-end of the PFI lines becomes limiting.  If you have an available specification document for your FGEN I'd like to be able to see it.

  I hope this gets you throw on the right track to solve the problem - impatience comes back with more information.

• Units of the number of samples and rates for the DAQ Assistant units

  Hello

  I use the DAQ assistant for analog voltage of an input OR data acquisition card. What is the difference between the rate and the number of samples in the DAQ assistant and what are the units of the two?

  Thank you.

  The number of samples is how many discrete to measures. Rate (per second) is how fast to acquire the specified number of samples.

  If number of samples is 100 and the rate is 1000 samples per second, then the acquisition would take 0.1 second (100 / 1000).

• How constantly sample meter signal for quadrature linear encoder

  Hi all

  Trying to permanently change value of Schneeberger linear encoder quadrature at certain frequency as 10 Hz of the sample and the output to the text file. Everything I choose in the external clock that I can't run the DAQ assistant. No one knows how to fix? I don't know what kind of clock can be used.

  I have read a few replies that ppl would connect to an another sample clock in parallel with the meter channel. But I don't know what is the principle of operation of this method.

  I spent already as 10hours on it. Could someone tell me that some information?

  Looking forwad to your help! Thank you very much!

  Best regards

  George

  Hi George,.

  You'll want to use the DAQmx API rather than the DAQ Assistant.

  The task of the encoder itself would look like this.  You need not use the trigger options.

  The problem is that you will need to generate a clock from another source that the card is unable to generate examples of clock counter directly.  The simplest is probably to use the second counter.  Here is an example showing how to use a meter to output as a sample clock (although the example shows the analog inputs, simply replace the task of analog input with the task of the encoder shown in the previous example, I linked).

  So, you would use a counter (say ctr0) for the task of the encoder, and then the other (ctr1) meter for the generation of sample clock.  You must specify your task of encoder using the InternalOutput of ctr1 as the sample clock (if the internal counter output appear in the drop-down menu, click with the right button on the terminal and select the e/s name filtering > include Advanced terminals).  Start the encoder task before the output task (although given that both are running continuous it doesn't really matter that much).

  In addition, 10 Hz is not too fast.  If the exact date is not as important and the above seems a little overwhelming, it might be easier for you to just run a loop of 100ms clocked by the software from example like this.  Note that the exact time loop pourrait will vary from cycle to cycle, so this method is not very good if you use sampled data to perform calculations of rates.

• My Pavilion G7 suddenly can't recognize the WiFi Signal for the second time in a year

  Hi all

  My flag is about two years old and the

  motherboard has been replaced by HP in virtue

  For the second time in nine months the laptop suddenly can't recognize my router

  WiFi signal. This time if I do a system reinstall, I'll have to reinstall 50 apps! I try to avoid this if possible. I understand that changing the bios settings can set wifi problem but no idea how this step will affect files (delete/save). Upgraded to WIN7 to 8 to 8.1. Help, please. Thank you very much.

  Hi BHK6,

  Yep, installation of adapter Qualcomm Atheros WiFi update worked!

  It worked immediately, but I wanted to give him a full 24 hours or more to see if the fix stuck.

  This problem seems to be resolved.  Now I can finally return to my much delayed project.

  Thanks a lot for helping me through this. :-)

• Can not see the values for the value of the field Position Flex games

  Hello
  
  I want to see the values associated with the Position to flex fields segments set of values. The valueset is the section of Position Flex field of the HRMS.
  When I go on request > FlexField > key > values and look for the defined value, it does not appear in the list of value games. I am unable to find a game for any segment of values. The two sets of value are at table in function.
  Can someone tell me why I can't see them?

• Number sequence for the value in the column group

  I need to create a sequnece number in a column from 5, and incrementing 5, based on the presenet values in the first column. If the value in the first column changes then the sequence would start with 5 and an increment of 5.
  
  for example: I want to generate the following output
  
  Cat_code Seq_No
  1001 5
  1001 10
  1001 15
  1001 20
  5 2001
  10 2001
  15, 2001
  3001 5
  10-3001
  4001 5
  4001 10
  4001 15
  4001 20
  5001 5
  6001 5
  5 7001
  7001 10
  7001 15
  7001 20
  7001-25
  
  So if the cat_code changes, the sequence number should still start at 5 and should be to generate the sequence number until the cat_code changes again.
  
  any help apreciated.
  
  Thank you
  Rahul

  Hi, Rahul,

  You can use the analytical function of the ROW_NUMEBR to generate the numbers, like this:

  SELECT       cat_code
  ,       5 * ROW_NUMBER () OVER ( PARTITION BY  cat_code
                                   ORDER BY        NULL
                       )       AS seq_no
  FROM       table_x
  ORDER BY  cat_code
  ,            seq_no
  ;
  

  You must use an ORDER byclause of Analytics when you call ROW_NUMBER. If you don't really care the order, so you can ORDER BY a constant, but you still need the analytical ORDER BY clause.

• In any case for the value Compenent of the list is NOT anti-aliased text?

  As you may know, pixel fonts are tiny size, specially created for NOT being anti-aliasing. Use you the size of 8, with anti-aliasing pixels, the value "bitmap (no anti-alias) '.
  
  But I can't find how to specify this parameter for a list item type. I can incorporate the police and get to use the police, but he alias against it. Any ideas? Thank you

  Nevermind, it seems that the clip that the List component was inside was not aligned to pixels the same.

• Creation of the logic group - no limitation for the value of criteria field?

  I am trying to create simple logical groups in FDM (11.1.1.3 and 11.1.2.1 version). However, an error message is displayed in the information bar.
  
  : Error adding the new record.
  Detail: data access error.
  
  I clicked on the button "Add" and created a logical group that contains * 1 520 * accounts not sequential sources in the field of value of criteria (with operator).
  I separated these accounts from source with a comma and no space between them. (Note: operator = x, value/Exp = 1, Seq = 0) I've updated the grid. Then the error message was displayed and the logical group create failed.
  
  And then, I created a new group of logic that contains only * 100 * accounts not sequential sources in the field of value of criteria (with operator).
  I also separated a comma, no spaces and the same setting. I've updated the grid. And the logical group has been successfully added.
  
  The account of each source contains 10 characters (alphabet and number).
  
  I want to ask:
  1. is there a limitation by specifying accounts sources (i.e.. more than number of accounts for each group of logic source) in the criteria value field when creating simple logical group?
  
  2. I'm adding these logical groups by clicking on the button 'Add' one by one, is it faster way to do (i.e. transfer an excel or csv source file specified accounts)?
  
  Thank you very much!

  You perform the update the named range in the Excel file as the previous poster said? When you import an Excel file using the import XLS function, only the name family (s) starting with 'ups' are actually loaded in the system. Note that at least in versions 9.3 and 11.1.1.3 there was also some hidden lines had to be such that specify the header.

• A question about the sections for the value/element pairs

  Hi Oracle Texters,
  
  In Oracle 11 GR 1 material with an index of context, is it possible and if so, how, to implement the sections for:
  

  <a>
       <item>name</item>
       <value>fred</value>
  </a>
  <a>
       <item>nickname</item>
       <value>trooper</value>
  </a>

  So, something like: (this syntax is probably wrong, but gives the gist of what I'm trying to do)
  

  (name within item and fred within value) within a

  Returns a line, that there is a 'name' and 'fred' in one section "a".
  
  But I don't want to return a row the following:
  

  (name within item and trooper within value) within a

  As "trooper" is a "nickname" not a "name".
  
  
  When I create sections of the area 'a', 'item' and 'value' two of these expressions return a line.
  
  If this is not possible, or how to get the result, please do let me know.
  
  Thank you very much
  Gary.

• Best practices for the period average upgrade R12

  Someone know where I can find a documented Oracle advised at the time to perform the upgrade 12.1.1? We are looking at whether we can pass in the middle of a period or if we have to wait until the closing period.

  Best practice is to read the name of a forum before posting in it.

  This forum is titled: "Oracle Database General Questions."

  My suspicion is that your question relates to EBS.
