B1.1 VP System Configuration-2

Web客户端站
这是一台基于Windows的计算机，其中Exarqe / Exasmoc视图通过使用Web服务器的Internet接口显示。其不需要安装APC客户端。
Exaopc
Exaopc是一个在CENTUM CS 3000/1000 DCS和应用软件（如Exasmoc在线控制器）之间提供OPC（开放工厂连接）基础标准接口的服务器。由于Exasmoc是客户端，它通过Exaopc服务器读取/写入FCS上的相关过程数据。
Vnet / IP
Vnet / IP是连接HIS，FCS，HIS / ENG，Exasmoc和Exaopc等站点的一条100 Mbps实时控制总线。V net用于CENTUM CS 3000 DCS。其可以是单或双冗余总线。
Ethernet
HIS，HIS / ENG，Exasmoc站，Exaopc站和可选的远程监控站（用于Exasmoc）可以在Ethernet上连接。CENTUM CS 3000和1000 DCS中的以太网具有以下功能 -

• HIS趋势数据文件传送到PC端；
• 在两台HIS上调整数据；
• 传输HIS上Exasmoc操作员窗口的相关Exasmoc数据；
• 传输来自远程监控站上Exasmoc VB Windows的相关Exasmoc数据。

系统配置组件说明

人机界面站（HIS）
HIS主要用于操作和监视 - 它显示了用户快速掌握工厂运行状态所需的过程变量，控制参数，报警，图表等。
HIS还将通过其专门构建的操作员窗口面板对Exasmoc控制器执行操作和监视功能。下一节将提供关于使用这些面板的详细信息。其允许操作员使用公共站进行标准操作，监视和控制以及Exasmoc的先进过程控制，监视操作。
桌面类型的HIS是在Windows上运行的通用个人计算机。
控制台类型HIS是在Windows上运行的高端站。除了桌面型HIS功能外，它还具有类似于CENTUM前身的功能。

现场控制站（FCS）
除了许多其它功能之外，FCS主要控制BRC和ERC模式的工厂。如果用户在项目中使用COAST模块，则它将在FCS下运行。根据项目需要，用户系统可以是标准FCS（LFCS）和/或Compact FCS（SFCS）。

工程师站（ENG）
这是具有工程师权限的PC，可用于执行CENTUM CS 3000/1000系统生成和维护管理。它可以是与HIS相同类型的通用PC，甚至可以是普通PC。

Web Client station
This is a Windows based computer where Exarqe/Exasmoc views are displayed via Web Server using Internet Interface. APC client installation is unnecessary.
Exaopc
Exaopc is a server, offering an OPC (Open Product Connectivity) Foundation standard interface between CENTUM CS 3000/1000 DCS and application Software such as Exasmoc online controller. As Exasmoc is client, it reads/writes process related data on FCS through Exaopc server.
Vnet/IP
Vnet/IP is a 100 Mbps real time control bus, which links stations such as HIS, FCS, HIS/ENG, Exasmoc and Exaopc. V net is used on CENTUM CS 3000 DCS. This can be single or dual redundant bus.
Ethernet
HIS, HIS/ENG, Exasmoc station, Exaopc station, and optional remote monitoring station (for Exasmoc) can be connected on Ethernet. Ethernet in CENTUM CS 3000 and 1000 DCS has following functions –

• HIS trend data files to PC’s
• Equalizing data in two HIS’
• Exasmoc related data to and from Exasmoc operator windows on HIS.
• Exasmoc related data to and from Exasmoc VB Windows on remote monitoring station.

  The system configuration shown here is in generic nature. For the details of users system configuration, user shall refer to respective project documentation.

B1.2 CS3000 System Configuration
The following is a typical system configuration which includes Exasmoc station and Exaopc interface with CENTUM CS 3000 DCS.
Users’ actual system configuration will be similar to one of these typical system configurations.

Description of System Configuration components
Human Interface Station (HIS)
The HIS is mainly used for operation and monitoring – it displays process variables, control parameters, alarms, graphics etc. necessary for users to quickly grasp the operating status of the plant.
The HIS will also perform operation and monitoring function for Exasmoc controller through it’s specially built operator window panels. Next section will provide detailed information on working with these panels. This allows operator to use a common station for standard operation, monitoring and control along with Exasmoc’s Advanced Process Control, monitoring operations.
Desktop type HIS is a generic personal computer running on Windows.
Console type HIS is the high-end station running on Windows. In addition to desktop type HIS functionality it also incorporates functionality similar to its CENTUM predecessors.

Field Control Station (FCS)
The FCS mainly controls the plant in BRC and ERC modes besides its many other functions. If the COAST modules are used in the user project then it is intended to run under FCS. A Users system may have Standard FCS (LFCS) and/or Compact FCS (SFCS) depending on project demand.
Engineering PC (ENG)
This is the PC with engineering function used to perform CENTUM CS 3000/1000-system generation and maintenance management. It can be the same type of general purpose PC as the HIS, and can even be the same PC as the.
