SCADA and Communications

People new to the industry often use the terms SCADA (Supervisory control and data acquisition) and DCS (Distributed Control System) interchangeably. Although there's no sharp line separating these two categories of control systems, and specific implementations often have characteristics of each, it is useful to distinguish between them because of their unique strength and weaknesess.

The most significant factor differentiating SCADA system and DCS today is the "human in the loop". Well, enough about those explanation. It can be more technical and quite difficult to absorb for some people who are not really familiar with both control system.

To makes thing simpler and easier to understand what are SCADA and DCS, lets see their characteristics:

SCADA System
1. Geographic span: Large
2. Point count : Large
3. Data acquisition rates : Moderate - seconds to minute
4. Data acquisition network : Slow with moderate error rate
5. Graphic User Interfase (GUI) : Full featured
6. Alarming subsystem : Full featured
7. Control actions : Human initiated

DCS System
1. Geographic span : Small
2. Point count : Small
3. Data acquisition rates : Very fast - miliseconds to seconds
4. Data acquisition network : Fast with low error rate
5. Graphic User Interfase (GUI) : Basic
6. Alarming subsystem : Basic
7. Control actions : Programmatically initiated

Perhaps, later I'll slowly explain about these type of control systems...We must know and appreciate these system as it smoothen our process control and operation. These control system are applied in the oil & gas as well as in refineries too serving the oils and fats industries.
