Maria,
Just to add my 2 cents... As Tim indicated, faceplates evolved from the 1970s
generation of Foxboro's analog instrumentation; SPEC200 Single-Loop Control
Stations. The faceplate graphical display was created to look exactly like the
front of the SPEC200 Control Stations so it was easier for all of the older
operators to adapt to them. As for graphics vs. faceplates, I find the ideal
displays are graphics that are drawn to represent the process configuration
with pickable symbols that call up 1/8 or 1/4 screen faceplates. Operators
generally monitor the process from the graphic displays and can get immediate
control of a final element (valves, pumps, dampers, etc.) by picking on the
symbol that calls up the faceplate.

Maria,
I think the answer is that yes, Faceplates are a vestige of an earlier era when
Symbols did not have the functionality they do now with aliases. I went back in
the archives and it looks like from the Release Notes, aliases were introduced
in Version 8.0 of FoxDraw/FoxView.
I still use Faceplates in some applications because of the ease of use. When
adding a Faceplate to a graphic, all you need to tell it is the Compound and
Block, and it makes all the connections to that C:B for you. This is useful
when you know that you only want to work with a PIDA or an AIN block to
accomplish some task, which is often the case. However, I also use Symbols when
I need to connect to multiple blocks at the same time, which is something you
can't do with Faceplates. Any given Faceplate can be connected to only one
specific block at a time.
I started using FoxDraw/FoxView when Faceplates were all you had to automate a
task, so I tend to think in those terms when creating FoxView screens and
default to them. Others who started after aliases became available use them
exclusively and don't even consider Faceplates, in my experience.

Hello dear list, I have some companies having only Symbols, but some only
have Faceplates. I never liked the Faceplates as they are unflexible.
What is the benefit of Faceplates and why do they exist? Perhaps it is a
historic thing I am not aware of? best regards Baumgartner
