CP450-T-ETH面向对象的分布式直接数字系统 DCS模型的核心是包含控制功能块。功能块是从早期更原始的“表格驱动”软件的DDC概念发展而来的。面向对象软件的第一个实施例之一，功能块是自包含的代码“块”,它模拟模拟硬件控制组件并执行对过程控制至关重要的任务，例如PID算法的执行。
CP450-T-ETH分布式控制器、工作站和其他计算元件之间的数字通信(点对点访问)是DCS的主要优势之一。注意力被适当地集中在网络上，网络提供了所有重要的通信线路，对于过程应用，网络必须包含特定的功能，例如确定性和冗余性。

The core of CP450-T-ETH object-oriented distributed direct digital system DCS model is the control function block. Function blocks evolved from the DDC concept of earlier, more primitive “table-driven” software. One of the first embodiments of object-oriented software, a function block is a self-contained “block” of code that simulates a hardware control component and performs tasks critical to process control, such as the execution of the PID algorithm.
CP450-T-ETH Digital communication (point-to-point access) between distributed controllers, workstations and other computing elements is one of the main advantages of DCS. Attention is appropriately focused on the network, which provides all the important lines of communication, and for process applications, the network must contain specific functions, such as determinism and redundancy.
