8507-BI-DP GE 总线接口模块

*  技术参数说明：

8507-BI-DP (Bus Interface Module) BIM提供PAC8000系列io模块与PROFIBUS-DP主机之间的通信链路。从模块和高达12 Mbaud的LAN操作速度高速采集数据，使主机能够快速响应过程条件的变化。
BIM收集I/O模块的数据，并根据需要提供给主机。它是PROFIBUS主站的从站。除了读取输入和写入输出数据所需的循环数据交换外，BIM还支持PROFIBUS扩展诊断(PROFIBUS Extended Diagnostics)状态信息。
BIM必须与第4页描述的8701-CA-BI冗余BIM Carrier配套使用。冗余bim可用于关键应用程序。冗余对中的每个BIM并行运行，不断检查状态，使备用BIM能够监控主用BIM的健康状态。8507-BI-DP总线接口模块
BIM的安装和操作请参见《PAC8000 I/O – PROFIBUS DP BIM说明书》INM8507。

参数化
8507-BI-DP支持从PROFIBUS主机进行参数化。使用GSD文件中提供的详细信息，在PROFIBUS配置器中创建配置。这种方法速度很快，并且能够基于表示物理模块的“逻辑”模块来构建配置。模块一次添加一个到配置中。
在通信开始时，配置信息由PROFIBUS主站传递给BIM。当系统停止重启或节点冷启动时，配置文件会被重传到BIM中。

The 8507-BI-DP Bus Interface Module (BIM) provides the communications link between the PAC8000 series I/O modules and a PROFIBUS-DP host. High-speed acquisition of data from the modules and LAN operation speeds of up to 12 Mbaud allow the host to respond rapidly to changes in process conditions.
The BIM gathers data from the I/O modules and makes it available to the host upon request. It is a slave to the PROFIBUS master. As well as cyclic data exchange, which is required for reading input and writing output data, the BIM supports PROFIBUS Extended Diagnostics for status information.
The BIM(s) must be used with an 8701-CA-BI Redundant BIM Carrier, described on page 4. Redundant BIMs can be used for critical applications. Each BIM in the redundant pair operates in parallel, continually checking status to enable the backup BIM to monitor the health of the primary BIM. 8507-BI-DP Bus Interface Module
For details on the installation and operation of the BIM, refer to the PAC8000 I/O – PROFIBUS DP BIM Instruction Manual, INM8507.

Parameterization
The 8507-BI-DP supports parameterization from the PROFIBUS master. The configuration is created in a PROFIBUS configurator using details provided in a GSD file. This method is fast and enables a configuration to be built based upon “logical” modules which represent the physical modules. Modules are added one at a time to the configuration.
The configuration is passed from the PROFIBUS master to the BIM at the start of communication. If the system is stopped and re-started, or if the node goes through a cold start cycle, the configuration file is retransmitted to the BIM.
