Abstract: In simple terms, DCS is a system, PLC is a device, the two are not comparable, PLC is a product that can SCAOA system (it simply is a computer operating screen) together constitute the DCS.
As China's leading grinding systems integration service provider, CHAENG'S slag powder production lineconstruction of the project had already realized the intelligent control and management, also known as information management, every aspect of production has been applied information technology, which is being monitored, employees can by operating the control system to complete the daily production operations, there is use to improve production efficiency, ensure security and achieve greater efficiency.
CHAENG'S slag powder when the customer technical requirements expressly requested to make use of DCS, without allowing the use of PLC. So the question is, for a control system, we often hear the term DCS and PLC, many people will think DCS is PLC, DCS and PLC both in the end what is the difference?
Simply put, DCS is a system, PLC is a device, the two are not comparable, PLC is a product that can SCAOA system (it simply is a computer operating screen) together constitute the DCS.
1. DCS is mainly used for process automation, PLC is mainly used in factory automation (production line). If the terms of computers and networks, they are unified, the reason why there are differences, mainly on the needs of the application, DCS often require advanced control algorithms, such as in the oil refining industry: PLC processing speed is high, it is often used on the interlock, or even fail-safe systems.
2. PLC system, you can program the controller, was developed by the relay logic control systems for industrial measurement and control site, on-site monitoring and control functions, stable performance, high reliability, the technology is mature, widely used, the price is reasonable.
3. DCS system, the distributed control system engineering, process control is developed, is a 1990s international advanced level of large-scale control systems. It is suitable for measurement and control points, high precision measurement and control, monitoring and control speed industrial field, which is characterized by decentralized control and centralized monitoring with network communication capabilities, monitoring and control function is strong, reliable, easy to expand, easy configuration, operation and maintenance simple so and so, but the price is more expensive system.
4. PLC simple to implement logic functions and control, human-machine interface is not available, to achieve operation requires the use of lights and buttons, HMI and SCAOA system; PLC and DCS functionality and SCAOA both systems, but basically used in larger systems and demanding some control systems.
In summary, DCS and PLC is the biggest difference is the DCS system, PLC is a device consisting of DCS mouth.
In order to achieve cement, industrial waste and other industrial production and better integration of information technology, Siemens PLC and WINCC system composed of DCS control system. CHAENG is actively developing innovative ideas to improve cement, slag vertical mill project level of intelligence.
Future, CHAENG central control to build the hall, the most advanced information technology in the field of industrial milling, grinding production to achieve the "Made in China" to "Chinese wisdom made" changes.
