附录一 XDPS预定义标准功能块说明
99.8.23
一、概述
XDPS的软件功能分DPU和MMI，MMI又包括OPU、ENG、HSU等，DPU又有VDPU、专用GTW等。从C/S观点来 看，DPU、VDPU、专用GTW、HSU等又是服务器，其它为客户。所有软件功能可分解在不同的节点上实现。
XDPS的数据采集、报警检测、闭环控制、计算等必须在DPU上完成。DPU的计算控制可由工程师组态修改和调试。XDPS提供了符合IEC 1131－3标准的控制算法语言，特别强化了其中的以功能块为基本的图形组态和调试语言，使组态和调试非常直观方便。
XDPS提供了各种常用的功能块，用户只需从这些功能块 选出所需的，相互连接，就可实现DPU的图形组态，而无需了解编程语言。用户还可用XDPS的工具生成自已特殊的功能块。
二、DPU简介
DPU称为分布式处理单元，是XDPS的控制器。DPU是XDPS的一种功能，而并不具体到什
么硬件。我们往往将只实现DPU功能的软硬件一起称为DPU，将运行于MMI站上的DPU功能称VDPU，用于与外部设备接口的VDPU称为GTW。
每个DPU至少有一个节点号对应。DPU通过实时网或内部路由器与其它DPU和MMI连接，实时网可以是冗余的，可以采用不同协议。DPU可以通过I/O驱动与不同的I/O硬件连接。但有的DPU（如只实现计算统计功能的DPU）可以没有直接的I/O连接，而是仅通过实时网与其它DPU交换数据。
