Hello JFM,
One question about your idea. What happens if the RT fieldpoint was controlling a critical process in a factory during the period of time the module is unloaded and loaded again?.
With software of PLCs like Siemens, OMRON, ABB, Allend-Bradley, Phoenix Contact... this can be done very easy. So, I think that NI can implement this characteristic to the Real-Time Module: To change some pieces of code on-line when you are debugging the program but while the application is running in the real target.
Bye
