一、集散型控制系统的组态功能DCS的组态功能已成为工业界很熟悉的内容.一个DCS系统的组态功能的性能(包括它的应用方便程度,用户界面友好程度,功能的齐全程度等)是影响一个DCS是否受用户欢迎的重要因素.DCS的组态功能包括两个方面的内容:硬件组态(又叫系统配置)和软件组态.DCS的硬件结构一般采用标准的模块化结构(见第三讲).因为硬件模块的选择与系统的价格关系较为密切(特别是对国内用户),加上硬件的配置与现场的要求联系较紧,因此,硬件的基本配置在合同谈判阶段就已确定.常见的硬件配置包括以下几个方面的内容:工程师站的选择(包括机型、CRT尺寸,内存,硬盘容量,打印机等);操作员站的选择(包括操作员站的个数和每个操作员站的具体配置如CRT尺寸、是否采用双屏显示、主机型号、内存容量、磁盘容量、打印机的个数和型号);现场控制站的配置,包括现场控制站的个数,地域分布、每个现场控制站中所配的各种模板的种类及块数、电源的选择等.
First, the distributed control system configuration DCS configuration function has become familiar to the industry content.A DCS system configuration features (including its ease of use, user-friendliness, completeness of the function Etc.) is an important factor affecting whether a DCS is welcomed by users.DCS configuration features include two aspects: the hardware configuration (also known as system configuration) and software configuration.DCS hardware structure is generally standard modular Structure (see Lecture 3). Because the choice of hardware modules and the system’s price is more closely (especially for domestic users), coupled with the hardware configuration and site requirements tight, so the basic hardware configuration in the contract negotiations Phase has been identified.Common hardware configuration includes the following aspects: Engineer station selection (including the model, CRT size, memory, hard drive capacity, printers, etc.); operator station selection (including the operator station And the specific configuration of each operator station such as CRT size, dual-screen display, host model, memory capacity, disk capacity, the number of printers and models); field control station with , Including on-site station number, geographic distribution, select each field station in the distribution of the various block types and number of templates, and the like power supply.
