Answer Posted / khaled
DCS is a system distributed geographically and functionally
within the process areas. It can view and control the
porcess based on information received from process field
instrumentations and can do controlling through the human
machine interface or through logic built in the DCS
controllers.
SCADA, it is mainly a system in which the main controller
exist in the control room (master terminal unit) and
communicating with remote units (remote terminal units)
which gathering information from field
instrumentations.This system also can do controlling
through logic built in the main controller
