FOXBORO 福克斯波罗 P0972KX 模块 连接到以太网交换机

每个P0972KX模块具有单个10/100Mbps铜以太网连接和一个RJ-45模块前面的连接器用干连接到双端目以太网设备。P0972KX是连接到以太网交换机或集线器，以便与一个或‘’多64个外部设备通信外部设备，一对模块组合在一起提供冗余现场总线模块(FBM)级别。在这个配置中，一台P0972KX是Master，另一台是跟踪模块。控制站上的输入点是否从设备上接收到的输入更新连接到Master的网络。设备输出点(取决于1/Q驱动程序)由Master和Tracker模块。角色转换如果检测到问题(例如，1/O驱动程序导致的仟何设备的心跳丢失;或者用户口以随时切换角色SMDH。显示一般网络配置图1所示.

配置器

FDSI配置器设置P0972KX端口和基干XML的设备配置文件。港口配置器允许容易地设置每个端口的通信参数(例如，动态主机配置协议

P地址)。不需要设备配置器对于所有设备，但当需要时，它配置设备具体和点具体的考虑(例如，扫描速率，要传输的数据的地址，和

一次要传输的数据量事务)。操作

每对P0972KX‘’多可以接入64台设备来读写数据。

从Foxboro Evo控制站到P0972KX连接(参见图1)，直到2000分布式控制接口(DC1)数据连接可以用来读或写数据。支持数据类型由加载

的特定驱动程序决定P0972KX将数据转换为DCI数据类型如下:

口模拟输入或输出值(整数或IEEE)单精度浮点数)0单个数字输入或输出值

口多个(打包)数字输入或输出值(每组‘’多32个数字点连接)。

因此Foxboro Evo控制站可以访问到2000个模拟1/O值，或高达64000个数字!/O值，或数字值和模拟值的组合使用P0972KX。访问的

频率P0972KX的数据通过一个控制站可以像500ms。性能取决于每一个设备类型和设备中数据的布局。

Each P0972KX module has a single 10/100Mbps copper Ethernet connection and an RJ-45 module in front of the connector for dry connections to dual-ended Ethernet devices. The P0972KX is connected to an Ethernet switch or hub in order to communicate with one or more 64 external devices, a pair of modules combined to provide redundant fieldbus module (FBM) levels. In this configuration, one P0972KX is the Master and the other is the trace module. Whether the input point on the control station updates the network connected to the Master from the input received on the device. Device output points (depending on the 1/Q driver) are made by the Master and Tracker modules. If a problem is detected (for example, a 1/O driver causes a loss of heartbeat for a thousand Ho device; Or use the account to switch the role SMDH at any time. The general network configuration shown in Figure 1 is displayed.

The FDSI configurator sets the device configuration file for the P0972KX port and the base XML. Port configurators allow for easy setting of communication parameters for each port (for example, dynamic host configuration Protocol)

P address). Device configurator is not required for all devices, but when required, it configs devices specific and point-specific considerations (e.g., scan rate, address of data to be transferred, and

The amount of data transferred in one transaction). Controls

Each P0972KX pair can access up to 64 devices to read and write data.

A data connection from the Foxboro Evo control station to the P0972KX (see Figure 1) up to 2000 Distributed Control Interface (DC1) can be used to read or write data. Support data types loaded by

The specific driver decided P0972KX to convert data to DCI data type as follows:

Port analog input or output value (integer or IEEE) single-precision floating-point number)0 A single numeric input or output value

Port multiple (packaged) numeric input or output values (each set of 32 more numeric dots connected).

So the Foxboro Evo control station can access up to 2000 analog 1/O values, or up to 64,000 numbers! The /O value, or a combination of digital and analog values uses the P0972KX. visitorial

Frequency P0972KX data through a control station can be like 500ms. Performance depends on each device type and the layout of the data in the device.
