What Is Distributed Control System?(DCS) As the name itself says distributed control system has distributed controls throughout the plant area for handling large complex circuits with difference in geographical locations in industrial processes.
7 Important features of Distributed Control System. To deal with complicated processes: PLC- Programming Logic Controller is used for controlling and monitoring high speed process parameters in a factory automation structure but they cannot use complex structures because of the restriction of the number of input devices. But then Distributed Control System (DCS) is mostly suitable for complex systems where more than one input devices is used for example batch process control. Hence DCS is recommended for complicated management programs with more variety of I/O’s with devoted remotes. These are used in production procedures where developing of several products are in several procedures such as group procedure management.
System redundancy: DCS helps program accessibility when needed by same feature at every stage. It is always good to
have a resuming steady state system after the outputs rather than using automation control devices. System reliability is increased by maintaining the system operation on a non stop basis even during some fault while system is working. There are various algorithms and application libraries tested before hand along with functions which are predefined for handling large and complex systems. This saves a lot of time for programming and control for various applications.
Powerful Programming Languages: Ladder, function, block, and sequence are provided by this language for developing custom programming based on user interest.
More innovative HMI: Just like the SCADA program, DCS can also observe and manage through HMI’s (Human Machine Interface) and it provides data which is sufficient to the owner to charge over various procedures and it functions as heart of the program. But this type of industrial control system that includes vast regional areas whereas DCS covers only a small area. Just like a PC window, DCS takes the entire process plant as a control room. Logging, graphical representation, and new trends of the HMI’s give effective customer interface. For quick response of operators to the plant conditions, a powerful alarming system of DCS is used.
Scalable platform: By adding more clients to the communication system or by adding lots of input output devices in distributed controllers, DCS can be based on scaling various input/outputs from a range of small to large server.
System security: For plant safety access to various control processes are used. DCS offers help for better safety automation control as it offers better security system for handling the automation control. Protection is also offered at different levels such as entrepreneur level, engineer level, user stage, etc. Join the electrical training institute in Pune to make your a successful career in electrical engineering.
