On the other hand, SCADA concentrates more on acquisition process data and presenting it to the operators and control centre. Hence, DCS does not keep a database of process parameter values as it always in connection with its data source, whereas SCADA maintains a database to log the parameter values which can be further retrieved for operator display and this makes the SCADA to present the last recorded values if the base station unable to get the new values from a remote location. This is used to operate, monitor and control plant parameters. The answer, like most things in the world of automation, is that it depends on the needs of your application. A DCS takes much longer to process data, so it’s not the right solution when response times are critical. DCS’s were designed to control processes, not discrete operations.
