SIEMENS Distributed Control System (DCS) is known as process control system (PCS), is a digitally working industrial control system (ICS) that controls distributed control loops in industrial plants or machines. It fulfills the tasks of process control technology. A distributed control system differs from a central control system in that each individual control circuit can carry out its own control. The individual control circuits are self-sufficient and connected to one another via a communication network. Process control systems are used to control industrial processes and improve their safety and reliability. They are used in many industrial systems. In chemical production processesand in petrochemical plants, in electricity and nuclear power plants, in food production and in water treatment plants and in many other industrial facilities. The process control system is functionally comparable to the network control system SCADA, in which data is recorded, saved and analyzed in real time . Both concepts work with a remote control center. Process control systems must be real-time capable, as well as high availability ensure and supportthe interoperability of different components.

Scalability O DCS

Although a PLC is able to process many I / O points, a DCS can process many thousands of I / O points. With a modular or subsystem architecture, you can add new devices to a DCS. Throughout the day’s you have a large system in which parts of your process are scattered all over the place, a DCS will support you much better.

Redundancy

In the same way, the DCS also has an advantage here over a PLC. You can add as many controllers and networks as you can afford. And if there is a problem, it will not affect your monitoring and control, provided that you have your redundant equipment set up correctly. This feature makes your system more reliable because it can keep running regardless of potential problems.

Complexity

No surprises await you here! The more complex your system becomes, the more likely it is that you will opt for a DCS over a PLC. A DCS enables multiple processes and products as well as multiple devices in your system.

Benefits Of DCS

• Shared use of resources (printer, files, memory…..etc)
• Openness: Possibility to add proprietary resources (from different manufacturers)
• Parallelism: Different processes can be executed on different processors at the same 
• time
• Scalability: Increasing the performance of the system by adding components
• Fault tolerance: Tolerance of failure of hardware and software through the use of 
• alternative hardware and software components
• Transparency: User does not need to know the distribution
• Low costs (PC, LAN)

• Oil and Gas (upstream)
• Chemical industry and specialty chemicals
• Power generation
• Hydrocarbon processing
• Life sciences and pharmaceutical industries
• Metallurgy, mining and mineralogy
• Water and sewage
• drug
