Sean, my experience is that you do a number of core modules (Analytical Methods for engineers, project management, engineering science etc etc), then the other modules depict what award you get

I took HNC & Hnd Mechatronics, so was heavily into PLC's, Robotics, etc etc, but found that i was only one or two modules different from the guys taking things like HNc Instrumentation & controls. For a lot of the time we had three or four different HNC disciplines in the same class, and even more on the HND

good luck!
