Which statement is false about Distributed Control Systems (DCS)?

The statement regarding plant operators always being onsite in a control room to monitor the process is misleading because Distributed Control Systems (DCS) enable remote monitoring capabilities. One of the key advantages of a DCS is that it allows operators to manage processes from various locations rather than being physically present in a centralized control room. This remote access can enhance operational efficiency and flexibility, as operators can adjust system settings, respond to alarms, and monitor data from different sites or even on mobile devices.

In contrast, the other statements highlight essential features of DCS: operators truly can monitor operations remotely, the system automates processes to improve efficiency, and DCS integrates with other systems to provide real-time data for better decision-making. Thus, the emphasis on requiring operators to be onsite contradicts the fundamental design and purpose of a DCS.
