Integrated cRIO Serial Port under FPGA Interface

[Quintino]

I've a cRIO-9074 that has one Serial Port. I need to build an application that must run in the cRIO that can communicate with this Serial Port (Just send some bytes and read a response). I've done this only in Scan Interface, but when I quit LabVIEW the system just stop (do I need to do this in FPGA Interface to get VI always running in the cRIO?).

The problem is, when I try to program in FPGA Interface, I do not have access to the Serial Port. When using the FPGA I/O, I can only get the Chassis Temperature, FPGA LED, Scan Clock, Sleep and System Reset.

Please help.

Hello,

And thank you for posting here.

Even when using Scan Interface, you can get a VI always running on your cRIO. You have to build a specification :

At the bottom of your project window, with a right click on "Build Specifications", you can create a New -> Real-Time Application. Select and add your starting VI in the properties of your specification, set "Run as startup" by doing a right click on your specification. And it should works...

Tell me if it's what you wanted.
