Merit:
1. High reliability: The DCS system has multiple redundancy, backup and recovery mechanisms, which can ensure the high reliability and stability of the system.
2. Sensitivity: The DCS system can be customized according to different industrial processes to meet different control requirements.
3. Efficiency: The DCS system can realize real-time control and monitoring, and improve the production efficiency and quality of the factory.
4. Easy maintenance: The hardware and software components of the DCS system can be maintained and upgraded separately, reducing the cost and risk of system maintenance.
Shortcoming:
1. Protection: Since the DCS system involves the control and monitoring of industrial processes, once it is intruded, it may cause protection problems.
2. Technical threshold: The design, R&D and maintenance of DCS system requires technical personnel, and there are high requirements for technical threshold.
3. High cost: Because the DCS system requires a large number of hardware equipment and software systems, its cost is high, and the investment in the enterprise is also large.
4. Difficulties in system integration: Since the DCS system is usually composed of multiple distributed controllers and input and output modules, system integration and debugging are difficult, and long-term debugging and optimization are required.
