SCADA is an abbreviation for Supervisory Control and Data
Acquisition .
DCS stands for Distributed Control System.
Normally, a SCADA system will get the data from a RTU
(remote terminal unit). A RTU runs independently, except
for some control from the central supervisory system such
as fire fighting, emergency shut-down (i.e water & oil
pipelines). The communication path will be through a GSM,
wireless technology, etc...
For a DCS system, it controls the process as a stand-alone
system. It has the control loops built into it's own
controller. The communication path will be through
something like a LAN high-speed Ethernet, or other
communications network. DCS is a single unit, or a group of
local units
