I am "upgrading" from real time 7.1. To 8.0. I use a headless PXI chassis with a RT-8145 controller. The unit is used to collect data from vehicles under rough road conditions.
One requirement I have is to set the clock on the headless PXI system. Currently I set the time by running an executable on a laptop and downloading this to the PXI. This application then runs on the PXI and I can configure an set the clock via a remote connection on the Laptop.
How can this be done in LV8? I do not have space to put an executable on the PXI to boot at startup. My perferred method is to download the file to the PXI (when the startup application is not running) make the changes an quit the aplication freeing up memory for the PXI controller to save more data files. (The 8145 controller uses compact flash as the hard drive [512Mb] and is limited to running a program and saving data no larger than 128Mb [controller RAM size] .
With this setup i can aquire about ten triggers of data collection.
See the application note touting labview real time feature to do this (for Lv7.1).
