I haven't dipped my toe into academic ethics in a number of years, but I very clearly remember it was a big thing among ethics philosophy people of the time to stress that ethics in philosophy was the study of ethical systems (differing from morality in the way the previous post described). Perhaps this was a dominant school of thought at the time, but the profs and literature we studied both where pretty clear about this.
