I’m not very skilled; I hope the more experienced among you can give me some guidance. It would be great if the explanations could be simpler
DCS stands for Distributed Control System, while SIS refers to the plant-level real-time monitoring system. DCS is designed to enable distributed control and centralized operation. SIS is aimed at achieving integrated control.
1 Composition: DCS does not contain a detection execution unit； The SIS system includes a detection execution unit. 2 Function: DCS ensures that the production process operates under normal conditions and even at optimal levels ； SIS system for safe shutdown in case of over-limit conditions. 3: Operation: DCS dynamic continuous ； The SIS system is static and intermittent. 4 Security Level: DCS low, no certification required ； The SIS system has a high security level and requires authentication.
DCS is the abbreviation for Distributed Control System, while SIS is the abbreviation for Safety Control System
Does every chemical plant have an SIS? ?
Reply to 6# Gavintao: No, it depends on the process requirements, and there are also **relevant mandatory regulations.
