Issue Details

I have the model that I will use, compiled from Simulink to work with NI Veristand. I need to know the way to configure the RS232 hardware on RT target and work with NI VeriStand.


NI VeriStand implementation doesn't provide any configurable access to RS232/422. However, you can create your own Custom Device (CD) or work with the existing Instrument Add-on Custom Device to extend the NI Veristand Framework to address this functionality.

Although VeriStand provides most of the general functionality required by a real-time testing application, NI has designed the environment so that you can customize and extend it when necessary to ensure it always meets your application requirements. NI VeriStand custom devices are created with NI LabVIEW software using a template library installed with NI VeriStand that includes interfaces to the NI VeriStand data and timing resources.

Additional Information

All of the common tasks or functionality of a real-time test system have been implemented and optimized inside the NI VeriStand Engine. The additional functionalities can be addressed with help of Custom devices which have the ability to behave as native tasks within the NI VeriStand Engine. In the Veristand Add-ons document you will see a collection of NI supported VeriStand add-ons as well as additional add-ons gathered from internal NI developers and the VeriStand community.
