2. Am I correct in my understanding that EPICS is meant primarily for managing systems data and systems control, rather than the core scientific data from an experiment (e.g. bandwidth-heavy high-speed cameras with 300 Hz image updates, fast digitizers,
etc)?
EPICS plays a large role in integrating all sorts of devices. It's probably fair to say that these are often large numbers of PLCs or similar relatively slow devices that use various network protocols, and EPICS makes them available via a common network
protocol, providing a common API, common operator displays and related control system tools.
But the fact that many sites have thus vast numbers of "slow" PVs doesn't mean that EPICS isn't fundamentally able to handle faster devices as Mark just mentioned. The overall limitation would be the network or CPU infrastructure, not EPICS.
