• Need help with the function or metric derivative to calculate percentages of threshold for a measure

  Hi, first post to the community that I am a n00b Foglight needing help.

  A thing (in fact the only thing) I like Microsoft SCOM is how this graph of the availability of a metric, and I want to do the same thing in Foglight. I understand that this could be a derived measure or a function, I need, but am a bit lost right now.

  Let's say I have a metric and created thresholds as follows: normal included 0, 50 inclusive, warning critical 75 inclusive, fatal 100 inclusive + 9999 included. The metric is measured every so often and more often (99%) of the time it's normal. I want to visually represent that fact, together with the percentage of time that he spends in the strips of quick, critical and fatal alert threshold.

  For the dashboard but mainly reports I am looking for the percentage of time that the metric through each of the bands of threshold and put them in some form of chart, preferably very similar to how SCOM it: -.

  

  I would also like to increase this visually with a quantification for the oriented numercally, in order to insert values in the report for clarification would be great too, for example:-Normal:-99% 0.5% warning critical Fatal 0.1% 0.4%

  I think of what I have already learned that we have to include a 'blue' band for threshold indefinite in order to operate on a regular basis for any measure.

  I do not seem to come up with this concept in Foglight but I think it could be very useful to have something. Any help is most appreciated.

  Health and alarms is a standard display which can be used on any object topology.  You can access it from the data browser and should also be able to specify this dashboard as a preference in personalized dashboards.

  

  Here it is in a custom dashboard:

  

• Should I purchase Measurement Studio and NI-IMAQ separately or NOR-Imaq included in measurement studio?

  
  

  Hi Vjuno,

  Thank you for your interest in Measurement Studio and NOR-IMAQ. Measurement Studio and NOR-Vision are separate software packages. If you are considering comes to acquire, save and display images from a camera IEEE our NI Vision Acquisition software located on our website (http://sine.ni.com/nips/cds/view/p/lang/en/nid/12892). If you want to set up a system of image analysis then you can buy the Module OR Vision Development, this includes NI Vision Acquisition (http://sine.ni.com/nips/cds/view/p/lang/en/nid/2881).

  Thank you for your interest in our products!

• cDAQ9184 for the measurement of the angular position...

  
  

  Hello

  It works now... Thanks for the customer support OR. The measure of the angular position uses a signal generated internally by using a counter ("/ cDAQ1/Ctr1InternalOutput").

• 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.

  Best regards

• How can I use reverse imaq for USB video camera?

  Hello

  I'm trying "opposite" a video image live.  I try to use the "Imaq Inverse" VI and it works for photos, however, I can't it works with a camera USB which is striking images.

  I get an error "not an image" that occurs in the Imaq reverse VI when I image acquisition to enter USB plugged into the Img Src for the Inverse VI.

  Any suggestions how to get around this problem?

  I enclose two files.  The "Live video" VI allows the user to acquire video directly from a USB camera.  The VI 'Negative video Live' is the file I'm having a problem with.

  Thanks for your help!

  Hello

  I guess your camera deliver RGB images (even you initialized the 8-bit image).

  If so, try this way:

• Train of SVM IMAQ for no Image data

  Hello

  I am fairly new to machine algorithms for learning about Labview so please be patient if my question seems stupid. I was wondering if there is a workaround to use the screw of Machine Vision SVM (e.g. IMAQ SVM Train) for not the image data. I know Machine learning package and I will surely give it a try with those but MV screws are really well organized and allow to record the training in a very elegant manner.

  Indications, suggestions or, well, even a "no, can't it' is really appreciated!

  Moreover, any luck of having the learning algorithm Machine present natively in LV?

  Thank you

  FRAX

  -According to my knowledge IMAQ screws are specifically for the Images.

  -Your best chance is using Machine learning package that you have already found.

• filtering data for temperature measurement

  Hi, need some help here.

  Before I add in the filter, I get the graph like figure 'graph-1. PNG ". But it is false because impossible, temperatures can drop to 30 0 30 0 31 0...

  After I add in the filter (as shown in the "filter graph n. PNG"), the chart is to look like figure 'graph-filter. PNG'. The graph move continuously in but the scale of the x-axis is changed.

  So, how can I solve this problem in order to get the graph constantly move (will not fall back to zero) and the x-axis of the correct scale (for example, 0 to 50 degrees Celsius). What kind of filter should I use.

  emergency aid!

  THX.

  Cournoyer,

  To my knowledge no instrument will not give this temperature difference, I would like to know how you measure the temperature before you apply the filter check your labview code if your postal code here, I can help you more.

• CYC can be used for several measures thermocouple?

  Hello

  I intend to use a PCI 6221 with the SCB-68 to 3 temperature measurements (2 on a surface of copper that will be controlled at 40 ° C) and 1 for air at 20 ° C using thermocouples T and cold welding of the SCB-68 Compensation. From what I understand, once that the switches were properly set, AI0/AI8 are used by the CCM. So I have to use AI1/AI9 in differential mode for my first Thermocouple.

  (1) will be Thc n ° 2 and n ° 3 (respectively placed in AL10/AI2 and AI3/AI11) be Thc also compensated by CCM?

  (2) does anyone otherwise a kind of accuracy can I expect with thermocouple T + CJC allowance? Ideally, I would like to join a +/-0.2 ° C accuracy.

  Thank you very much

  Yes

  (2) does anyone otherwise a kind of accuracy can I expect with thermocouple T + CJC allowance? Ideally, I would like to join a +/-0.2 ° C accuracy.

  First, take a look in the spec 6221.  in the CCM SCB - 68 spec and finally to the specification of the TC used.  Rough estimate: +-2 ° C without individual calibration.

  To meet the uncertainties of 0.2 ° C for type T TC (without the CJC and EMF meter) only you would need a calibration of liquid bath agitated the point of interest.

  0.2 ° C is for RTDS like Pt100...

• update dynamic image imaq for nuclear design

  I do a simulator of nuclear reactors in labview program that allows the size to the top of the reactor to the power output. The part that I'm working on now creates circular table of pins to get a realistic PIN and geometric distribution. I already thought about the solution of series of pins available in Mathscript, but I can't get the pins imaq image to dynamically update when you change the number of "shells" in the table.

  I wrapped the PIN generator in a while loop and it will dynamically update in one direction only - you increase in the number of shells and pins is added, but it remains to be the largest number you entered when you reduce the number of shells.

  I am reasonably sure that there is some sort of glitch imaq. Any help would be appreciated!

  It is not a problem with your mathscript berries.  It seems that for every iteration of the loop you are simply more overlay overlay on the image.  So when you decrease the number of shells, it's just more oval drawing on top of your image.  You must remove the overlays before writing a new overlay at each iteration.  Use the function called "IMAQ Clear Overlay" at the start of each loop as shown in the image below.  You also put a break in your loop, so it's time to pull and is not flashing (50 ms pause should be good).  Another option rather than add a break would be to place this code in a structure of the event that updates only when the value of the number of shells is changed.  Good luck!

  

• Source of the logical table for a measure in OBIEE 11 g!

  Hi all

  Can you help me with the following scenario please.

  For example, we have a metric of revenue that has 2 LTS - an annual level and the other at the quarterly level.

  We sometimes use the measure of income in the analysis. How the BI server will know what LTS to hit for data?

  Thank you very much in advance!

  -Ajay.

  It will take the LTS with the priority level set low. If the LTSS is the same level of priority that you want to create and define a hierarchy of dimension (year, quarter, month, date on your time Dim) and set your LTSS on appropriate levels. If you count the rank is defined by level in your SUN, the repository will choose most appropriate source (less records) for the request.

• Unable to load the extension for Rotator easy - no CC2015 program in the extension manager?

  I try to install Easy Rotator (dwuser.com) in Dreamweaver CC 2015. I run the program on a nearly identical machine with great success, but can not get the zxp file to be allowed to be charged on this machine. I use windows 7 pro and don't see any CC 2015 programs listed in the extension manager. I heard that Ext Manager cannot be used with CC 2015 but can't get anything to work... Help, please... Thank you!

  Unless EZ Rotator is available on the page Adobe modules, you can not install it in 2015 CC because Adobe has stopped the extensions Manager.

  You can - maybe but not guaranteed - install it with a 3rd party DMX Zone EM, but I doubt little.

• Year percentage change from year ago last for a measurement

  Hello Experts,
  I have a report that has column year and sales, revenues, profits and they ask me to give a percentage change in sales last year. Could you please help me how can I me he and the syntax for that. Please notify.
  
  Thank you
  RC
  
  Published by: user1146711 on December 14, 2011 08:32

  Yes it is possible to do it on your reports with OBIEE 11 g, but still, you should check that you have a time dimension with chronological key and levels laid down in the RPD.
  Try first in the report and check if your have the correct results or not.
  AGO(meausre,Level,1)
  the level is at your level of the year and 1 is the number of bearing period in this case because you want only the measurement 1 year ago.

• KeyboardEvent for rotation and Flip

  I am turning or flip an object with this code keyboard event

  Stop();
  stage.addEventListener (KeyboardEvent.KEY_DOWN, onKeyPressed);
  function onKeyPressed(evt:KeyboardEvent):void {}
  {Switch (evt.keycode)}
  case Keyboard.R:
  MOD. Rotation += 90;
  break;
  Keyboard.H case:
  mod.scaleX * = - 1;
  break;
  case Keyboard.V:
  mod.scaleY * = - 1;
  break;
  by default:
  trace ("code:", evt.keyCode);
  }
  };

  but it returns these erros:

  1119: access of property may be undefined R through a reference with static type class.

  1119: access of property may be undefined H through a reference with static type class.

  1119: access of property may be undefined V through a reference with static type class.

  Who can help me to fix this problem.

  Thank you

  Right, the Keyboard.R and the others are for AIR only. You must use the key codes themselves. Try this:

  stage.addEventListener (KeyboardEvent.KEY_DOWN, onKeyPressed);
  function onKeyPressed(evt:KeyboardEvent):void {}
  {Switch (evt.keycode)}
  82 decision:
  MOD. Rotation += 90;
  break;
  72 decision:
  mod.scaleX * = - 1;
  break;
  decision 86:
  mod.scaleY * = - 1;
  break;
  by default:
  trace ("code:", evt.keyCode);
  }
  };
