using the local monitor from a pxi labview rt system as the HMI without a pc attached.

[riddick99]

I typically connect a pc to a labview rt systems to act as the hmi, but now I want to use the local monitor and keyboard+mouse

to be the HMI for a Labview RT system running on a PXI controller like the pxi 8104 and labview rt.,I do not want  to have a pc connected to the system.

Can the LVRT   vi front panel be displayed locally?

If not, what can be displayed on the local monitor ?

Can the local mouse and keyboard be used?

Is NI-Imaq or something else needed to display  graphics?

Please let me know

thanks

Hi riddick99,

To answer your questions:

          "Can the LVRT   vi front panel be displayed locally?"

-The front panel does not run on an RT System, so you cannot view it with a monitor attached. 

"If not, what can be displayed on the local monitor ?"

      -The local monitor displays the current CPU and memory usage and other debug messages of the RTOS.  You can use the RT Debug String.vi (Real-Time»RT Utilities) to output messages to the Video Console or the Serial Port.

"Can the local mouse and keyboard be used?"

              -You can use the Serial Port to use the keyboard as an input device, but it's probably easier to use the HMI interface you currently have. 

"Is NI-Imaq or something else needed to display  graphics?"

              -Graphics cannot be displayed on the console output

Just to clarify for future people looking this up: graphics can indeed be output on the monitor of a RT system. This is only avaiable through NI-IMAQ.

Hi All,

I wanted to add that the new NI Real-Time Hypervisor is capable of running both LabVIEW Real-Time and Windows XP in parallel on PXI-8108 and PXI-8110 controllers. This is one potential solution for running LabVIEW Real-Time code with a UI on the same controller (no need for another PC).

Does it mean that any image may be displayed using functions of the NI-IMAQ library on a monitor attached to the video output of a PXI embedded real-time controller (without NI Real-Time Hypervisor and the need of a second core running Windows) ?

Thanx for further information,

If you have the Vision Acquisition Software (in which the NI-IMAQ driver is included), you will have access to the Image Display control on the front panel of your VI. So, if you are using functions such as IMAQ Read File or IMAQ Snap to get your image, you will be able to view the image on the front panel of your VI.

Sorry! I take that back. To display it on the output of your PXI RT controller, you would need to use the IMAQ RT Video Out VI. The Image Display control would not apply to your situation as you have an RT system.
