UAD155A0111是ABB公司生產(chǎn)的一款集散控制系統(tǒng)。
UAD155A0111是ABB公司生產(chǎn)的集散控制系統(tǒng)，由輸入輸出模塊、通信模塊、控制器和人機界面組成，是一種以控制器和現(xiàn)場設(shè)備為基礎(chǔ)，將相關(guān)工藝信號匯集到系統(tǒng)中，由操作站進行監(jiān)視或其他控制操作，以分散控制、集中操作、分級管理為主要特征的工業(yè)自動化控制系統(tǒng)。與PLC側(cè)重于局部邏輯控制相比，DCS更注重模擬量的控制，因此DCS系統(tǒng)擁有更強的數(shù)據(jù)傳輸和管理能力，這也是大型項目廣泛應(yīng)用DCS系統(tǒng)的主要原因。

集散控制系統(tǒng)，又稱DCS系統(tǒng)。
集散控制系統(tǒng)是以微處理器為基礎(chǔ)，采用控制功能分散、顯示操作集中、兼顧分而自治和綜合協(xié)調(diào)的設(shè)計原則的新一代儀表控制系統(tǒng)。集散控制系統(tǒng)簡稱DCS，也可直譯為“分散控制系統(tǒng)”或“分布式計算機控制系統(tǒng)”。它采用控制分散、操作和管理集中的基本設(shè)計思想，采用多層分級、合作自治的結(jié)構(gòu)形式。其主要特征是它的集中管理和分散控制。DCS在電力、冶金、石化等各行各業(yè)都獲得了極其廣泛的應(yīng)用。

UAD155A0111 is a distributed control system produced by ABB.
UAD155A0111 is a distributed control system produced by ABB, which is composed of input and output module, communication module, controller and man-machine interface. It is a kind of controller and field equipment based on which relevant process signals are gathered into the system, and the operation station is used for monitoring or other control operations. Industrial automation control system with decentralized control, centralized operation and hierarchical management as the main characteristics. Compared with PLC, which focuses on local logic control, DCS pays more attention to analog control, so DCS system has stronger data transmission and management capabilities, which is also the main reason why DCS system is widely used in large-scale projects.

Distributed control system, also known as DCS system.
Distributed control system is a new generation of instrument control system based on microprocessor, which adopts the design principle of decentralized control function, centralized display operation, taking into account division, autonomy and comprehensive coordination. The distributed control system is referred to as DCS, which can also be translated as “decentralized control system” or “distributed computer control system”. It adopts the basic design idea of decentralized control, centralized operation and management, and adopts the structure form of multi-level classification and cooperative autonomy. Its main feature is its centralized management and decentralized control. DCS has been widely used in power, metallurgy, petrochemical and other industries.
