Process Engineering Division – Instrumentation and Automation Section – Daily Question – Question from 2020-08-27: Discussion question: 217. What do the terms \"centralization\" and \"decentralization\" mean in a distributed control system?
The monitoring, operation, and management of the distributed control system are centralized, allowing operators to oversee and control it. Operators can monitor information related to the entire system as well as carry out control operations. The monitoring and control in a distributed control system are decentralized; the process variables detected by the field transmitters are sent to the field control stations, which then use control algorithms to directly control the actuators. One field control station controls a certain number of circuits, and a plant’s DCS system typically has several such field control stations.

Collection implies centralized operation and management, while dispersion means decentralized control
