LabView 8 and Mac --- no more reliance on Real-Time engine?

Does Labview 8.0 for Mac now support data acquisition WITHOUT having to export code via the Real Time engine? I've been using Labview 7.0 with E-series DAQ boards on Mac G4s, but have had to boot the mac in OS 9 for proper function of Labview with the DAQ boards. I would LOVE IT if I could now perform data acquition via OS 10.4 with my boards!

You can definitely use NI data acquisition devices with Mac OS X and
not rely on the real time cross-compiler. In January 2005, NI
released NI-DAQmx Base for Mac OS X. It currently supports about
80 plug-in DAQ devices, including M Series and the low-cost USB
devices, and development is similar to using NI-DAQmx.
Find out more about NI-DAQmx Base from the DAQ software page or ni.com/mac.
Also, you may want to check out the new LabVIEW tools for Tiger on
ni.com/mac. NI create a widget for viewing VIs, Automator
actions, and a plug-in to Spotlight for VIs and LLBs.

What are the limitations of using labview 8.5.1 developers suite verses a real-time module in field point applications?

What are the limitations of using labview 8.5.1 developers suite verses a real-time module in field point applications? Can an exe. be loaded onto a field point controller or does the controlling program have to reside on a PC for example?

centerbolt is correct, you can't load a .exe or even run a program on the fieldPoint controller unless you have the Real Time module. However, that does not mean you can't use your FieldPoint bank without the Real Time module.
From LabVIEW for windows you can make calls to the fieldpoint IO using the fieldpoint read/write functions.
This program runs on the PC not the FieldPoint controller. If you loose network connection to the fieldpoint, your program will loose connection to the IO. For many data logging applications this type of arrangement can work just fine. However, if this is the only type of application you are ever going to run, then you may as well not buy the Real Time controller for your fieldpoint but the network controller only.
If your application requires more reliability, and/or greater determinism than can be achieved by running a program on windows, then you should use the LabVIEW Real Time module and develop a program that can run down on the FieldPoint controller independent of windows.

File drag and drop with Labview 7 and Mac OS X Tiger?

Hi folks,
I've lost the ability to drag and drop files into front panel file path
controls, since I upgraded to a new OS X version. Specifically:
What used to work:
    - Labview 7.0
    - Mac OS X 10.3.x
    - drag file icon from desktop and drop onto file path control (file path control shows path to dropped file)
New action taken:
    - lost old Mac (Titanium) with OS X 10.3.x
    - bought new Mac (Aluminum) with OS X 10.4
    - installed OS X 10.4 "over" 10.3 disk (did not build from scratch)
What happens now (three days after birth of new system):
    - all my past Labview apps still seem to run
    - but, if I drag a file from the desktop and drop it onto the file path control I see:
          - file path control
"outlines" indicating that it understands the intended drag and drop
action
          - when the file is dropped the file path control does not report the new value
          - And the file path control still has it's old value
Anyone else seeing this? Am I missing something obvious (Labview or OS X preferences)?
Thanks in advance,
RMP

Hello,
I don't know how seriously Apple sees the problem, but it doesn't seem plausible that they would rev the OS on account of just this problem with LabVIEW, particularly since we worked around it for the latest version of LabVIEW. I understand you are working with another engineer at NI via direct email regarding this issue, and that is going to be a better forum for discussing the possibility of obtaining the Apple bug report number. In the event R&D is willing to reveal it, I presume they will be more comfortable doing so on a case by case basis, as opposed to posting it on the external discussion forum.
Thank you, and sorry for the inconvenience you have encountered due to this issue.

Can labview export shared libaray use in C++ without run-time engine?

Hi, everyone
Now, I write a VI for a algorithm and export it as a dll. I use the dll in my C++ apps. It is good. But I want to know how my apps can run without labview run-time engine or I must install run-time engine?

you can install run time engine or include dll which will be used by your application.

How to get signal from analog input and send it to analog output (real-time)

Hi everyone,
I am doing simple task in Visual C++ and I am using PCI-6221(37 pin).
Basically, I want to send same signal from 'analog input' to 'analog output'
at the same time (almost), to make it real-time application.
Can someone please provide me sample program.
I would appreciate if you could provide me with the good tutorial which explains
step by step everything about programing NI-DAQmx for C/C++.
Best Regards,
Khassan
Solved!
Go to Solution.

This is my code in C++, you can optimize it if it looks too messy. This code reads signal from analog input and outputs it through analog output.
To make this code work additional include directories and library directories must be added from NI.
I hope it helps someone.

Labview runs CANBus and DNP3 software model at the same time

I have an ordinary computer which communicates with several DSPs (CANBus communiation) through Compact Rio. The physical connection is that the DSPs' CANBuses are connected together and connected into Compact Rio, then the Compact Rio is connected with a router through Ethernet, at the same time, the computer also connects with the Router through Ethernet. Based on this physical architecture, the computer can run CANBus software model on Labview to communiate with Compact Rio and DSPs.
As I know, the communication between the computer and the Compact Rio is not real time, and the communication between Compact Rio and DSPs can be real time, can you tell me if I get the right point?
Now we have another device named RTDS (communicate with outside through Enternet based on DNP3), and want to add RTDS into our system. I am not sure about the way to conduct the communiation. The main question is that we need to run Labview to communicate with DSPs through CANBus and RTDS through DNP3 at the same time, is that possible?
I proposed two possible ways to conduct communication, bt not sure if it is possible.
1. I proposed that I connect RTDS with the Router through Ethernet, and then the computer communicates with RTDS through the Router based on DNP3 and also keeps the communication with DSPs through Router, Compact Rio, CANBus and then DSPs. I am wondering if this kind of communication is available for Labview.
2. The second possible way I proposed is that I connect the RTDS with Compat Rio (CRio keeps connecting with DSPs through CANBus) through Ethernet, and then the computer communicates with DSPs through Router, Compact Rio and CANBus, and the computer communicates with RTDS through Router, Compact Rio and Ethernet. Also, the computer needs to run Labview with CANBus sofeware model and DNP3 software model at the same time. I am also not sure if it is possible.
The diagram of the communication system is shown in the attachments.

To use Mail from multiple devices, your Mail Server needs to be using IMAP protocol (iCloud Mail uses that).
IMAP keeps the Master copies on the Server, not on the Mac the way most default POP Mail servers do.
To keep one Master Calendar, accessible from all devices, you need a web-accessible place to keep the Master Calendar. iCloud can do that.
¿Do you see a trend developing here?

Linked files broken in Photoshop CC 2014 when working in the cloud across multiple computers (PC and Mac)

I'm using the new linked file option in Photoshop CC 2014, which is great. I'm working with my files in the cloud, however because I'm working on both a PC and Mac it breaks them links every time I save the file. Is there a way around this?

Hi, yes I'm having the same issue. The problem is that Adobe is not correctly connecting the linked files. They are using absolute paths user/folder/folder this is just crazy and I hope they fix this.
Changing this will fix our issue.
I'm a professional web designer and I find the use of linked items really good. My workflow consists of creating a UI folder with different elements linked into photoshop documents saved in another folder.
UI - elements
Front page folder
Second page folder
etc.
Moving these folders is impossible. Making my life really hard.
Moving them to a network drive doesn't seem an option when you need to link all the files again, for each doc.
Adobe kudos on the idea now fix the paths so this is usable across computers.

Monitor my dogs with iSight and Mac

First, I'm a novice at all forms of electronic media but learning fast. I've moved to Scotland with my two dogs who must now live in the kitchen-laundry room during the day while I'm at work. I want to set up my mac powerbook G4 with Tiger OS and an iSight camera to send real time pictures of the dogs and what they are up to. I'd like to be able to watch them from my Dell PC at work and then hollar at them through some speakers when they are doing something they shouldn't be doing. Yes I know this is weird but hey why not if the technology is out there and I think it is. I just need some guidance on compatibility etc. Can anybody take this on and provide suggestions on setups, hardware, software, issues? Cheers

I use a great little application called EvoCam. It works with the iSight, has a great feature set. One thing I like about it is the built in webserver. This makes it very easy to setup and get running. I use it for my office and home webcams. I have not had any problems with it.

How to create a c++ shared library (.so) for linux real time (for myRio) with Eclipse to use in LabView?

I want use c++ codes on linux real time. For testing reasons I want to have a function that adds 2 values and gives the result.
I've done these steps:
1. writing a c++ file in Eclipse (see screensot 2)
2. building a shared library (.so) from my c++ project in Eclipse (with Cross GCC)
3. putting this file on myRio (path: /usr/local/lib/)
4. creating a VI that calls this library from Labview with a "Call Library Function Node" (see screenshot3)
5. Setting the properties for the "Call Library Function Node" (see screenshots 4-7)
After I run this VI i get this error message: LabVIEW: (Hex 0x627) The function name for the ... node cannot be found in the library. To correct this error, right-click the Call Library Function Node and select Configure from the shortcut menu. Then choose the correct function name. (see screenshot1)
I've tried a lot things to solve this problem but I couldn't find a solution. Would be very happy if anyone can help me. I guess that I have to edit my c++ code to export my function (symbol). But I have no idea how to make it. I also tried it with a dll file in the same folder but it didn't help.
Perhaps someone can send an example which works on myRIO.
Thanks!

can see it in the screenshot8 there is a function called "_Z8AddierenddPd" instead of "Addieren". I copied this name to Labview (see screenshot9) and it worked.
I'm sure that there is a way to compile the shared folder with gcc without decorations (mangling). But I don't know how. If someone has a recommendation I would be very glad!
Prepend each function declaration that you want to be available without name decoration with
extern "C" <your function declaration>
Or if you have multiple functions you want to export you can in the header file where you declare your functions simply use:
#ifdef __cplusplus
extern "C" {
#endif
<all your function declarations>
#ifdef __cplusplus
#endif

HOW CAN I ACQUIRE AND DEPLOY DATA IN REAL TIME WITH DAQ 6024E?

HI ENGINEER,
I'M PROGRAMING AN APLICATION WHICH I NEED ACUIRING AND DEPLOYING AN ANALOGOUS SIGNAL IN REAL TIME.
I HAVE:
LabVIEW 7.0
WINDOWS 2000
DAQ CARD 6024E
THE SIGNAL I WANT TO ACQUIRE IS 0-10 Vcd FROM A SENSOR, THE PROBLEM I HAVE, IS THAT I AM ACQUIERING THE DATA AND IT SEEM THAT THEY ARE UPDATING EACH SECOND, BUT I HAVE BEEN MOVING THE PARAMETERS SUCH AS TASK TIMING IN THE DAQ ASSISTANT VI AND NOTHING HAPPENS.
CAN YOU TELL ME WHICH PARAMETERS I HAVE TO MOVE TO AQUIRE AND DEPLOY DATA IN REAL TIME

Hi barron,
If you want to see the data update quicker, you can decrease the value in the "Samples to Read" field of your DAQ Assistant. This number controls when data is transferred from the DAQ buffer to the PC. If the sampling frequency remains the same, but this field decreases, it means the buffered data will be returned more quickly.
Hope this helps.
Thanks,
Lesley Y.

LabVIEW Run-Time Engine

Hi ,I have used Application Builder to make EXE file from my source files but I have noticed it is not possible to use this EXE file in another PC without LabVIEW because LabVIEW run-time engine is needed so I tryed Installer
but I have few questions and I would really appreciate if u help me
1- What kind of source files should be added to the installer? I would like to install an EXE file and Data folder so do I need to first use the application builder to make the application then add all the application files(EXE and Data folder) one by one to the installer or Do I need to add my LV files to the installer and LV make exe and data folder again for me?
2- I am using LV2010 and I would like to add run time engine for 2010 so I checked the box for LV2010 run time engine but many options are included to this engine like NI TDM,NI SSL etc ... and after making the installer I noticed the size of my file was so big (109MB) while I want to make a small size installer for email .Is there any chance to reduce the size of installer by unchecking some of the options?
Many thanks

You build an executable first, then you build an installer for the executable. When building the installer, simply add the executable and LabVIEW will figure out what else is needed in the typical case.
If you want a small installer, don't include the run time engine. Instruct your customers to donwload and install the free runtime engine from here.
Make sure they install the "standard", not "minimum" version. Also make sure they install the 32 bit version if your LabVIEW 32 bit, even if they install it under a 64 bit OS.

Error 1722 when uninstalling Labview run-time engine 7.1.1

I have been trying to uninstall all NI software so I can start off with a clean slate. I have been going to the control panel under add/remove programs to remove the NI stuff. Everything is gone except the Labview run-time engine 7.1.1. Everytime i try to remove it, i get teh 1722 error followed by the 1603 error. I've tried repairing it but I still get the same results when i try to remove it agian. I've also tried removing it with MSI Blast. This did not work either. I've gone through the registry and manually deleted anything related to NI and that still didn't work. Is there anything else I could try?
Thanks,
Nick

Hey Steve,
I have tried repairing it through the control panel.
I tried reinstalling just the run-time engine and it said it was already installed. So I reinstalled Labview 7.1 and repaired the 7.1.1 run-time engine through the control panel. Then I uninstalled everything. Thanks for all your help
Thanks again,
Nick

Can I run two separate versions of the LabVIEW Run-Time Engine on one PC?

Hello, I am curious if anyone knew if it is possibly to install and use two separate versions of the LabVIEW Run-Time Engine on one PC? I currently have the 2009 Run-Time Engine installed on one machine and wanted to install the 2011 Run-Time Engine as well. I know that you can run two separate versions of the LabVIEW program on one machine, but what about the Run-Time Engine?
Thanks!
Solved!
Go to Solution.

I'm guessing this is a bug that NI needs to fix. I see no reason you shouldn't be able to install the run-time engine of an older version. I'd be interesed in if it allows you to install the older development environment, which also includes the older run-time engine. There are some command line switches for NI installers as mentioned here:
http://digital.ni.com/public.nsf/allkb/C361087EE9F20810862577850073128E
I wonder if there is a force install option.
