The key to the DCS system is communication.It can also be said that the data bus is the backbone of the decentralized control system DCS.Since its task is to provide a communication network between all parts of the system,the design of the data bus itself determines the overall flexibility and security.The medium of the data bus can be:a pair of wire,coaxial cable or fiber optic cable.Through the design parameters of the data bus,it is basically possible to understand the relative strengths and weaknesses of a particular DCS system.

DCS系统的关键是通信。也可以说数据总线是分散控制系统DCS的脊柱。由于它的任务是为系统所有部件之间提供通信网络，因此，数据总线自身的设计就决定了总体的灵活性和安全性。数据总线的媒体可以是:一对绞线、同轴电缆或光纤电缆。通过数据总线的设计参数，基本上可以了解一个特定DCS系统的相对优点与弱点。
