  1. QUOTE (Dan DeFriese @ Nov 14 2008, 09:37 AM) Thanks! I did some more reading after seeing your post and think I have it figured out now! Thanks again. I'll let you know how it works out.
  2. QUOTE (Dan DeFriese @ Nov 13 2008, 09:40 AM) Mainly, I don't want to hide the wires. It would make it easier on the other folks if they can see them all and trace them easily, as on a typical schematic. The other reason is that I'm not familiar with structures either. I'm still learning the software as I go. I've attached the app in v8.5. Any help is appreciated!
  3. QUOTE (Dan DeFriese @ Nov 11 2008, 09:36 PM) I just need to be able to select different profile for each model engine. We can only test one at a time. I had to insert the app that Doon posted into the main loop for it to run properly. If that won't use more memory, then I can leave it as is. I have also figured out how to read csv files for the data I need for each model, but I have to change it (and the x and y axis ranges on the charts) when we run a different engine. I just need to be able to select the model when the main app starts, or I will have to create copies of the app with
  4. QUOTE (tmunsell @ Oct 29 2008, 02:23 PM) Well, everything seems to be working now. There's only a couple things left to do. I would like to figure out how to run multiple While Loops simultaneously, and set up my app to allow me to select the chart/data files to use for each engine model. I'm not sure if that will be easy, so I may just have to make copies of the main app for each model, since each model has different limits and ranges (for the X and Y axis). I'm also reading about how to manage the memory better. What I've read so far has been very vague, with no specific examples.
  5. QUOTE (Paul_at_Lowell @ Oct 29 2008, 01:11 PM) Thanks Paul. I had a feeling that is what I needed to do, but I was putting the Build Array on the broken line, which obviously didn't work. I'll give it an ops check tonight with our Fluke 725 and let you know how it works. Every day I'm learning more and more about LV, thanks to the good folks on this forum!
  6. QUOTE (Doon @ Oct 23 2008, 02:27 AM) OK, I've tried adding your app to mine, but I'm running into an error that I can't quite understand. As shown in the attached file, I connected the data (tapped into the wires going to the digital indicators for Pt7/Pt2 and EGT, and removed the sliders) and ran it into where your "DAQ inputs" were bundled. I'm not sure that the error message means. The data that I'm reading is DBL, so I thought it would work by inputting it as is. I'm sure I'm missing something obvious, but I've been reading and troubleshooting for 3 hours now and I'm getting a head
  7. QUOTE (Doon @ Oct 23 2008, 02:27 AM) Thank you very much, Doon and Minh Pham! You have been very helpful. The app you posted should save me a lot of time. I've always been better at "reverse-engineering" things, especially when it comes to learning a new programming language.
  8. Thanks for the info! The data we are receiving is from a Daytronic System 10 DAQ unit. We are currently displaying the data in real time in digital displays. There are no arrays for the data that I will need to plot. There are two inputs that need to be plotted on the graph (i.e. Engine RPM vs Engine Pressure Ratio). One needs to go to the X axis, and the other to the Y axis. I've tried just using a simple XY graph, but the live data isn't displaying at all, although it shows up fine on the main digital indicators that I am already using. As the engine accelerates, the engine pressure r
  9. Hi. I am currently attempting to display real-time performance values on a graph. I have the values needed in an xls file for the minimum and maximum limits. I would like to display these limits as lines on the graph, and then have the live data displayed on the same graph in real-time. This must be a continous process, during which time we are running a jet engine. This data will not be saved or printed, but only shown to aid the engine operator in judging the engine's performance during the test. I've attached a screenshot of the final graph which is created in Excel and printed for th
  10. Thanks. I'll see if they can download the files needed. The nearest rep is about 200 miles away from the test cell. I'll also be making backup copies of the DVDs that I can keep in the laptop case when I travel, just in case I need them. Thanks again. Todd
  11. I'm sorry, maybe I wasn't explaining the problem clearly. This is a first time installation of the app for the target PC. I want to build the app so it will run with just the run-time engine installed on the target PC, without having to install the entire LV program. But, for the build to work, it needs certain programs such as MAX and the NI-Serial drivers. It's when I select these to be added to the installer that it keeps asking for the DVDs. I'm out of town now, so I don't have access to the DVDs. I want to create the installer and email it to my workplace. Thanks. Todd
  12. I have been trying to create an installer for my app, but even though I have all the drivers loaded on my laptop, the builder keeps asking for the DVDs. I don't want to have to carry them around with me all the time (I do a lot of my programming while at home). Is there a way to create an installer without needing the DVDs? Will I have to copy each DVD to a folder on my laptop (wasting a lot of disk space)? Thanks! Todd Munsell WGP&W Industrial Turbine Services
  13. QUOTE(crelf @ Feb 14 2008, 04:06 PM) Thanks to you both for the info and the link. I'll check it out. I guess I forgot to mention that when I placed the four channels in the second loop, I did not have any wires connecting the two loops. I tried to run the second while loop that way, but it still only ran the main loop when I clicked the run button. I'll read some more and see if I can work it out tonight. Thanks again! Todd
  14. QUOTE(gleichman @ Feb 14 2008, 01:38 PM) Thanks for the reply, Alan. I think I understand what you are saying..... Please bear with me, since I am new to Labview (and programming in general), but I've been reading a lot about it lately in the book "LabVIEW for Everyone". What I'm trying to do is set up the two loops to operate simultaneously as part of the main app. I tried seperating the loops by putting the channel read subVIs inside the second loop, but when I ran the app, only the main loop ran. Nothing in the second loop worked.... no data flow at all. Do you know where I can f
  15. Hi, Well, the main app is running well, but I've run into another problem that I've been trying to figure out for 2 days. I need to slow the front panel display for just 4 channels from the Daytronic System 10. All the other channels need to update in real-time, which it is doing now. I tried creating a new while loop outside the main one, and placed the indicators in the second loop. But, when I run the app using highlight execution, the data flow stops at the tunnel in the main loop. I'm not getting any errors, but for some reason the data just stops at that point. What am I missing?
