Archived: Requirements for Running IMAQ Vision and IMAQ 2.6 (or Earlier) on LabVIEW RTThis document has been archived and is no longer updated by National Instruments
I have IMAQ Vision 6.1 for LabVIEW, which includes support for LabVIEW Real-Time (RT), installed on my computer. How do I configure my RT system to use IMAQ Vision?
The IMAQ Vision for LabVIEW Real-Time User Manual includes a detailed set of instructions for installing IMAQ and Vision onto an RT PXI controller. Below is a quick summary of the necessary configuration steps and required software for the host and target computers.
Note: The NI-IMAQ 3.0 driver has greatly simplified the configuration of IMAQ hardware on a LabVIEW RT system. The PXI system no longer needs to be booted into Windows in order to configure the hardware, rather this can all be done remotely from the host machine for all hardware supported by IMAQ 3.0 (the 1408 is supported under NI-IMAQ 3.0 using the older NI-IMAQ 2.6 driver).
To use IMAQ on a PXI system, you will need the following components:
The RT target must have a National Instruments PXI controller. The PXI controller should have a Windows OS installed with NI-IMAQ 2.5.1 or higher. Here is the list of steps to get your system running once all the software mentioned above is installed:
Some of the new functionality that comes with RT includes two new display VIs. The first is IMAQ Remote Compression VI. This VI sets up compression parameters for how you want images sent across the network to the Host machine. When you run IMAQ Vision applications on RT, any WindDraw function will try and send the image across the network and to optimize the speed of these transfers you can setup compression parameters. If the host is not connected, the code will skip over all WindDraw functions, so they don't slow down the performance.
The IMAQ WindDraw VI is synchronous, which means the code does not continue until WindDraw is done sending the data across the network, so this may slow down your application unless you set high compression values, or you don't use WindDraw. This is good for debugging purposes when you need to see the windows, or when you need to have the user select regions of interest. This method requires a
Another very powerful method of displaying images is PXI Video Out. This feature allows you to display images through the PXI controller's video port if you have a monitor attached. You can display only one image at a time on the monitor, since the image is displayed full-screen (it acts like one IMAQ window). When you use a window number of 15 for IMAQ WindDraw VI, it will display the image to the PXI controller's video port. This feature is only supported on the PXI-8175 and 8176 controllers. There is a VI called IMAQ Video Out Display Mode VI which allows you to configure the resolution and other settings of the monitor when displaying images. This method is much faster than remote display since the images do not have to be sent across the network and are not compressed.
Deploying Vision Systems:
For applications not running under LabVIEW RT, you will need to purchase the IMAQ Vision Deployment Engine (P/N 778044-01). This allows you to install the IMAQ Vision run-time engine with each executable you create and distribute. The Deployment Engine integrates with the LabVIEW Application Builder or a third party installer. The Deployment Engine CD includes a single deployment license. If you plan to distribute the executable to more than one target machine, you must purchase an additional IMAQ Vision Deployment license (P/N 778044-00) for each target machine.
For applications running under LabVIEW RT, you will need to purchase an RT license for each target machine as well as an IMAQ Vision for LabVIEW RT run time license (P/N 778628-00).
You will need to boot each target machine in windows, configure the boards in MAX, and run the
