FBM233 P0926GX 10/100Mbps的铜以太网连接

每个FBM233模块有一个10/100Mbps的铜以太网连接，模块前面有一个RJ-45连接器，用于连接双端口以太网设备。FBM233连接到以太网交换机或集线器，以便与一个或最多64个外部设备通信。
一对模块组合在现场总线模块(FBM)级别提供冗余。在此配置中，一台FBM233为Master，另一台为
跟踪模块。控制站上的输入点根据连接到主控的网络上接收到的设备输入进行更新。设备输出点(取决于I/O驱动程序)由Master和Tracker模块写入。如果I/O驱动程序检测到问题(例如，任何设备的心跳丢失)，则角色切换是自动的，或者用户可以随时通过SMDH切换角色。一般的网络配置如图1所示。

FBM233的主要特点是:
冗余10mbps或100mbps以太网传输速率到/从现场设备
与多达64个现场设备通信
I/O软件驱动程序可从可用协议库中下载
多达2000个DCI块连接
使用以太网连接将现场设备数据集成到Foxboro Evo控制数据库中
现场安装
G3类(恶劣)环境

这个FBM是一个通用的以太网硬件模块，可以在其中加载不同的软件驱动程序。这些驱动程序配置FBM来识别设备使用的特定协议。其中一些软件驱动程序是标准产品。
可以开发其他定制驱动程序来满足特定需求。这些驱动程序与专门设计用于与第三方设备协议接口的软件代码一起动态下载到FBM233。
每个驱动程序的配置过程和软件要求对于集成到系统中的设备是的。

Each FBM233 module has a single 10/100Mbps copper Ethernet connection and a single RJ-45 connector on the front of the module for connectivity to dual-ported Ethernet devices. The FBM233 is connected to Ethernet switches or hubs in order to communicate with one external device or up to 64 external devices.
A pair of modules combine to provide redundancy at the Fieldbus Module (FBM) level. In this configuration, one FBM233 is the Master, and the other is the
Tracker module. Input points on the control station are updated from the device inputs received on the network connected to the Master. Device output points, depending on the I/O driver, are written by both the Master and Tracker module. Role switching is automatic if problems are detected (for example, loss of heartbeat from any device) by the I/O driver, or the user can switch the roles at any time via SMDH. The general network configuration is shown in Figure 1.

Key features of the FBM233 are:
 Redundant 10 Mbps or 100 Mbps Ethernet network transmission rate to/from field devices
 Communicates with up to 64 field devices
 I/O software driver is downloadable from a library of available protocols
 Up to 2000 DCI block connections
 Integrates field device data into a Foxboro Evo control database using Ethernet connectivity
 Field mounted
 Class G3 (harsh) environments

This FBM is a generic Ethernet hardware module in which different software drivers can be loaded. These drivers configure the FBM to recognize a particular protocol used by the device. Several of these software drivers are a standard product offerings.
Other custom drivers can be developed to meet specific needs. These drivers are dynamically downloaded to the FBM233 with software code specifically designed to interface with the third party device’s protocol.
The configuration procedures and the software requirements for each driver are unique to the device(s) being integrated into the system.
