3.2 CI/CM PROFIBUS modules

CI/CM PROFIBUS模板

The AC 900F is designed for operation with different PROFIBUS communication interfaces like the CI 930F, CI 773F and CM 772F that can be connected on the left side of the PM CPU module。

AC 900F 专为具有不同 PROFIBUS 通信的操作而设计，像CI 930F、CI 773F和CM 772F这样可以在左侧连接PM CPU模块的一侧。

The module type CM 772F is supported by PM 901F and PM 902F, but not by PM 904F. CM 772只能被PM 901F和PM 902F，不能被PM 904F支持

PROFIBUS communication interfaces ensure communication via the PROFIBUSDP Fieldbus. The internal coupler bus connects the CI/CM with the CPU module. This applies to data and power supply. A dual-port RAM is used for data exchange 

PROFIBUS通讯接口确保通过PROFIBUS DP现场总线进行通讯。内部耦合器总线将CI/CM和CPU模板连接起来。这适用于数据和电源（指的是通过内部耦合器）。双端口RAM适用于数据交换。

3.2.1 CI 930F PROFIBUS-DP Master Interface

CI 930F PROFIBUS-DP主站接口

The below description applies to CI 930F with ordering numbers 3BDH....R0002 and ....R0005 only. CI 930F provides two on-board PROFIBUS interfaces A/B for increased availability regarding PROFIBUS communication

以下描述仅适用于订货编号为3BDH....R0002和3BDH ....R0005 的CI 930F，CI 930F提供了两个板载PROFIBUS接口A/B以提升PROFIBUS通讯可用性。

      Data arriving at CI 930F via the coupler bus are routed in parallel to both A and B connections. The first data coming in over line A or line B with a correct telegram start are routed to the coupler bus. With simultaneity, either line A or line B is selected at random. Testing and selection is always based on the first character. In the case of a telegram start with error on A, the control logic in CI 930F switches to the redundant line B. The same procedure applies vice-versa for line B.

       数据通过耦合器总线到达 CI 930F ， A 和 B 连接为平行路由。线路A或者线路B是第一批使用正确报文开头的数据到耦合器总线的路径。伴随同步性，选择线路A还是线路B是随机的。测试和选择始终基于第一个字符、在报文开头出错的情况下，CI930F的控制逻辑会切换到线路B，同样的道理，如果B线路出错，会自动切换到A。

LED status displays

LED灯状态显示

After having been switched on, the CI 930 PROFIBUS module performs a self-test during power-up. During initialization, with newly configured modules or after a change of the operating mode, all LEDs may light up briefly before reaching the defined status.

上电后，CI 930 PROFIBUS模板执行自检。在初始化过程中，使用新配置的模块或在操作模式更改后，所有 LED 可能会在达到定义状态之前短暂亮起。
