The DCS is integrated into a control architecture that contains supervisory-level controls that oversee multiple integrated subsystems that are responsible for controlling the details of the localization process.Product and process control is often achieved by deploying feedback or feed-forward control loops,where critical product and/or process conditions are automatically maintained near desired set points.To achieve the desired product and/or process tolerances around the specified set points,a specific programmable logic controller(PLC)is used in the field and the proportional,integral and/or differential settings on the PLC are adjusted to provide the desired tolerances and Self-correction rate during process disturbances.DCS is used extensively in process-based industries.

DCS集成为一个控制架构，包含监督多个集成子系统的监督级别的控制它们负责控制本地化流程的细节。产品和过程控制通常通过部署反馈或前馈控制环来实现，其中关键产品和／或工艺条件自动保持在所需的设定点附近。完成所需产品和／或工艺公差在指定的设定点附近，具体的可编程控制器（PLC）被用于现场，PLC上的比例，积分和／或差分设置被调整到提供期望的公差以及过程紊乱期间的自校正速率。使用DCS广泛地在基于过程的行业。
