• absolute time in the chart of mixed signals

  I am trying to build a chart of mixed signals with 4 inputs (Temp, Temp setpoint, % RH and set RH %).  I want the X axis to be absolute time, but do not know how to wire properly.  To search the help files and discussion forums, I think I should include a timestamp as a DBL.  So far, I have created 3 scenarios:

  • All of the lines of work but x 4 entered is relative.
  • Two main lines of work and entered x is absolute time (below)
  • Even with 4 inputs graphic breeze with an error that the number of entries in cluster does not match (away).  ???

  I seem to be missing something basic.  I would be very happy to anyone help... until the computer gets!

  PS LV8.5/WinXP Pro

  

  

  There seems to be a problem with the time of the x axis when you enter analog data tables and the waveform of digital data. Try the attached vi where you are piping the analog data as waveforms. Allows always to look at the data as it is collected over a period of time, which is what it seems you are trying to do. It also has a clear function. My example is rough; It would probably be best done with loops producer-consumer or one event loop to make it more effective. Let me know if this does not work.

• Xantrex HPD for LabVIEW 2009 pilot

  I saw there are other products OR with drivers for Xantrex HPD feeds.

  Someone at - it one that works for LabVIEW 2009 (or earlier)?

  Ok.  I have it.

  HyperTerminal has worked.

  He checked that port settings and command syntax is correct.

  ALL programs in LabVIEW examples do not have the function of VC to food.  When I hard coded the CR function after the order (also preprogrammed) it worked.  Xantrex (now Sorensen) manual do include SOME simple examples - you just know by experience (catch 22) how do.

  Also be noted that we need to send both a voltage and current definition commands because both are zero by default.  (If you send one, nothing SEEMS to happen because the other is 0).  That could also have been included in an example of beginning.

  THANKS for your help!

• Attend for Instrument i/o for Labview 2009 trial?

  I use the Evaluation Version of LabView 2009.

  Unfortunately, the Assistant of the Instrument-I/O is not currently available.

  If I try to add an Assistant for Instrument-I/O-Express-VI (exit), I get an error message telling me that the Measurement & Automation Explorer or assistant for Instrument-I/O has not been installed correctly. The Measurement & Automation Explorer is installed.

  Is it possible to use this Express VI into the evaluation version?

  Hey,.

  The Instrument of e/s assist is part of the VISA driver.

  Just look for the latest Version of NI VISA or the DeviceDrivers under ni.com (drivers and updates).

• Is there an Excel to TDM plugin for LabVIEW 2009

  I downloaded the Excel to TDM plugin and could not run. Dialog error usiReg said "this configuration file was created with a new version of the ICU and can not be used with the software you have installed." I installed LabVIEW 2009 SP1 and the .net version is 4.0. Y at - it another version of the 9

  the plugin I can use? Is there something else I can do, or am I just out of luck, until I update?

  Hello

  the functionality to open Excel files has been added to the ICU starting with version 1.8. However, the ICU in the manner described above upgrade you will register to use ExcelTDM and make it available through the _openWithRoot.vi in LabVIEW 2009. Simply install or DIAdem 2010 NI LabVIEW 2010 as a demo version.

  Please see also the comments from readers on the page of ExcelTDM use, a client has requested the use of using Excel in older versions of DIAdem:

• Mixed Signal graphic = > line of bad names

  Hello

  I want to use a graph of Mixed Signal and I noticed that the digital waveforms line names are not properly displayed.

  For example:

  The attributes of the wave the nams of line are defined as "Name1" "Name2"; "Name3"...

  On the graph of Mixed Signal, the first line is correctly called 'Name1' but all the others are called "Digital 1-> Line 0"; ' " Digital 2-> line 0 '...

  Is this a bug in LabView?

  If you use a normal digital chart, all names are displayed correctly.

  Yes, I know that I can change the linenames with a property node, but it should also work with the attributes of waveform.

  And a small second question: why are there no digital and mixed-signal graphics cards? I always build them manually...

  Best regards

  Reinhard

  Hello Reinhard,

  I think I found a link that might cover your problem. Looks like it has been known for some time

  How can I assign names to my digital waveform shown mixed graphic Signal?

• Control chart SPC not showing CL UCL or LCL

  Hi people,

  I have a spc control chart in my application.  However for some reason any of the UCL, CL and LCL are not displayed on my chart.

  A brief review of the facts:

  This is an application for people who enter the measurement data in several numberboxes the average that goes on the chart.  These figures vary generally from 32.0 to 28.0

  UCL is 30.6 the CL at 30 and LCL 29.4 However none of these values are showing on the chart.

  Someone used this command and find out why, I'm having a problem here?

  Hey Rik,

  I just had a quick play with this contorl and have had no problem to show the limits.

  

  I have attached the VI below, have a play and see if it works.

• Convert a chart 2D with various sizes for Mixed Signal

  Hi all

  I have a table 2D with, for example, 5 signals with each 100 data points (so a table of 5 x 100).

  I want to show each table on a graph of mixed signals. I have a solution that works for this problem (see attachment).

  My problem is that the number of signals and therefore the size of 2D array is variable. So the next time I run the VI, the table can be, for example, an array of 6 x 200. In this case I can't show all 6 plots on a graph of signal mixd my working solution.

  I was looking for a 'Table 2D to the cluster' function in Labview (see attachment) but unfortunally it is unavailable (perhaps a tip for developers ).

  Is there someone who has a solution for my problem?

  Thanks in advance,

  Patrick

  

  Why can't we just plug them directly together?  Mixed Signal graphics take an array as input 2D type.

  

• Tab control: chart automatically resets when I switch between tabs

  Hello world

  I'm having a problem with a user interface. : mansad:

  I use a tab with two tabs control to switch between the two graphs. A graph shows data from a production machine (tab 1), the other a data from a measuring probe (table 2). Now, when I switch from tab to tab 2 1 and return, graphic of tab 1 is empty and begins to show the data from the moment of return too tab 1. Tab 2 data are not reset, but are constantly updated, even when the 1 tab is open. I'd like to tab 1 to behave like tab 2. It must be constantly updated even when tab 2 is opened and the data should not be reset after between tabs.

  Making machine is connected via a server (Data tab 1, Figure 1), the data from the probe are written a queue and comes from (Data tab 2, Figure 2). It's all part of the main VI. This part is shown in Picture 3. Here, historical data are reset to zero when the program ends. But I can't understand why it does not work as I want.

  Can anyone help?

  Thank you!

  

  OK, there are very strange things happening here, in addition to the problem you are having (which, I admit, I don't see yet why you have a problem).

  First of all, I've never met such a structure of strange and deeply nested directory for LabVIEW code as what you posted: Users\AB\BC\CD\DE\EF\FG\GH\HI\IJ\.  Why in the world you have an empty stack of sense files / directories to go?  Very, very strange.

  You view multiple charts using waveform graphs.  Do you, indeed, assemble an array of waveforms to display on the chart, but the waveform consists of a single point, 'built' in a table, with a current timestamp as t0.  Instead of going to all these efforts, you can simply group your data points in a Cluster and show that.  Your X axis will not display "Time now", but if you know the sampling frequency, you can adjust the X scale so it displays 'Time' in practical (such as seconds) since the beginning of the sampling units.  Note that you already have one such cluster (at least in the reading process data - the data output Process value - which can be connected directly on the diagram of fluid bed without the need of the Signalverlaufsdiagramm).  It could, in fact, "fix" your problem (but I'll let you test this).  You will need to do a similar Cluster Bundle in sight Parsum data and output the cluster instead of the table in order to test this idea.

• How to trace the temperature and voltage using the graph of Mixed Signal

  Hello

  I use the NOR cDAQ-9178, module NI 9214 (temperature) and the module NI 9201 (voltage). My program allows the user to choose among 3 different tasks, Masurement of temperature, voltage, or both. When you select the task for temperature and voltage measurement, I was drawing all channels on the same graph. I was invited to separate channels of temperature and voltage and draw on a split graph, using the same category axis. I tried stacking, but could not control where each parcel channel went. I think the Mixed Signal graph would work well. Everything works and records all the data of the channels to the files, but my plots appear not on the graph, although I can see the change in scale numbers. I think I can use the cluster incorrectly. Can someone tell me what I am doing wrong? I selected the 'Plot Visible' option, but the plot is not always displayed. I've attached a zip with all the screws needed to run my program. The main VI is "Voltage_Temperature_SingleTask_Measurements_MAIN.vi"... but everything must be downloaded to the program works. Please help... Thank you.

  Hi mzhlb,

  I complained only the expressVIs.

  

  Why not use simple IndexArray function to get bots waveforms of your waveform table? (I faked it your DAQmxRead with functions SigGen).

• graph of the mixed signals on wrong tab

  I have alarge program. In one of the screws sub in the first run a graph of mixed signal appears on the wrong tab. If I clict on the second tab, whaere graph must be, it seems normal. If I go back to the first, the ghost of the chart image is gone.

  Also, if I left the program normally process in the second executionl, the ghost image disappeared.

  Y at - there anythign I can do to stop this behavior?

  I already tried to reinstall previous versions od my software, but it continues to be.
