，当前的过程数据或过程状态可以数字或模拟形式进行显示(如棒图、动态填充或
趋势窗口)。画面显示中的图形符号可根据过程状态进行置換、闪烁、变色以及位置变化，即进行动
操作管理级主要包括操作站、工程师站、数据网关、管理计算机及相应软件，另外还包括打印
机、操作台等辅助设备。操作站的任务是生产监控，即综合监视来自过程控制级的所有信息，进行监
示、报警、趋势生成、记录、打印输出及人工千预操作(发送命令、修改参数等)。工程师站用于系
统软件组态和调试投运，它无需永久性接入系统，操作站也可兼作工程师站(需按工程师权限登
录)。
操作站及工程师站硬件均为标准的PC机(通用型或工业加强型甚至是便携机)，采用微软公司
Windows 2000操作系统(中英文版均可)。因此PC机的配置水平与PC市场主流配置及最新的技术发
展保持同步并可根据用户要求确定。显示器的尺寸可选(17”/19”/21″ )，还可选择触屏功能
(19″ ).数据及命令输入- -般由标准键盘和Mouse(鼠标)实现，但操作站也可按用户要求选配IP65工
业薄膜键盘和符合人类工程学标准的光电轨迹球。另外还可配备针式打印机用于打印报表，彩色喷墨
打印机用于图形硬拷贝。操作台用于放置操作管理级设备(PC 主机置于操作台内，显示器等外设置于
操作台上)。
操作员站上的操作监控软件DigiVis及工程师站上的组态调试软件CBF (Control Build F)是操
作管理级必须的软件(均基于Windows 2000 操作系统)。另外可选的软件主要有权限锁定软件
(DigiLock)、批量控制软件DigiBatch)、运行在管理PC机上的生产数据浏览软件(DigiBrowse)及运
行在数据网关PC上的开放数据接口软件(Di giDDE，DigiOPC， DigiAPI).
5.2操作监控软件DigiVis
DigiVis的功能包括图形显示、数据监视、系统状态显示、趋势归档、记录、过程及系统报警、
报表、操作指导、下达控制指令、系统诊断等。DigiVis 具有中文版，更加便于国内用户使用。
DigiVis软件有如下特性:
系统信息的层次化分布使操作清楚迅速
变量的直接快速搜索
o
采用统一信息概念、清晰的信息显示和操作员提示
DigiVis图形显示种类包括自由图形显示(工艺流程等)及大量标准显示，下面将 分别介绍:
自由圜形显示
自由图形显示是按照裴置工艺和操作员的专门需要进行组态的，用以表示工艺过程状态的显示画
面，工艺流程画面是典型的自由图形显示。
在自由图形中，当前的过程数据或过程状态可以数字或模拟形式进行显示(如棒图、动态填充或
趋势窗口) .画面显示中的图形符号可根据过程状态进行置换、闪烁、变色以及位置变化，即进行动

, PROFIBUS is the most widely used open fieldbus international standard in the world, which is divided into FMS, DP and pa
Level III, DP communication rate can be up to 12MB. PROFIBUS is used to connect distributed i/0 stations, field bus instruments and other intelligent devices.
The communication among process station, operator station and engineer station is realized through the system bus diginets (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin cable, thick cable or optical fiber cable and mixed media) and network topology can be selected for the system bus
Due to the adoption of tcp/ip protocol, the system can also realize ultra long distance communication with the help of public telephone network (dial-up mode) or satellite.
PLC and other subsystems communicate with industrial “system through Modbus protocol interface. The system also supports iec870-5 over control coordination
Discussion.
The flash EPROM inside PS provides more than 220 function modules (control algorithm subroutines), in addition to the base specified in IEC 61131 3 standard
In addition to this content, many powerful and strictly tested function blocks from practical engineering applications are also expanded. Any complex control
All schemes can be realized by the combination of these function blocks.
The function blocks provided by the system mainly fall into the following categories:
o
Analog quantity processing
o
Digital quantity processing
Loop adjustment
Logical sequence control
c
Logical operation
Monitoring function
Acquisition function
c
Arithmetic operation
c
Tcp/ip protocol communication interface
Modbus protocol communication interface
1ec870-5 protocol communication interface (telecontrol)
4.2 field controller PS
Industrial ial “field controller PS is a special process control station, which is embedded with a fieldbus communication interface for users to use
Fieldbus technology provides a very flexible choice. Each PS is allowed to insert 4 fieldbus interface cards (card types can be different),
Each card is connected to a fieldbus to collect process data and diagnostic information from the bus. The interface card is easy to replace and plug and play
(plug & play) and can be plugged in and out with power.
The field controller PS has the following features:
o
Flexible: it supports all international standard open fieldbus and can be mixed
4 high-speed fieldbuses can be connected at the same time (max. 12 MBD)
Simple project: only use the same tool CBF (control build f) software for configuration, debugging and diagnosis
mouth
Access to all information from the site, including equipment management information
Global database of Fieldbus equipment, control level and HMI (human-machine interface)
Module identification with production operating parameters
c
Complete self diagnosis
Compact and rugged design
Front panel wiring
DIN rail (U-shaped) mounting well can be directly installed on the wall, which is simple and convenient
Open CAN -Bus，up to 1 MBd
o
Ethernet network card ei801f/ei802f/ei803f
o
Fieldbus interface card fi810f/fi820f/fi830f
