3.3 CI CAN Bus module
CAN总线接口通讯模板
An AC 900F controller with CI 910F CAN Bus module allows for connecting rack based I/O modules.
带有CAN总线模板的AC 900F控制器允许连接基于IO模板的机架（就像前面的Profibus-DP总线一样，DP主在控制器机架上，IO模板在DP从机架上）
3.3.1 CI 910F CAN Bus interface
CI 901F CAN总线接口
The CI 910F CAN Bus interface comprises three CAN Bus lines, CAN 1 to CAN 3. The lines are electrically isolated from the system and designed for redundant operation with a second AC 900F controller.
CI 910F CAN总线接口包括3条CAN总线线缆，CAN1到CAN3。线路与电气隔离，设计通过第二AC900F控制器实现冗余操作。
The internal coupler bus connects the CI 910 F to the CPU module. This is valid for both data transmission and power supply. A dual port RAM is used for data exchange.
内部耦合器总线连接CI 910F和CPU模板，这对数据传输和供电都有效果。双端口RAM用于数据交换。

LED status displays
LED状态灯显示
After having been switched on, the CI 910F CAN Bus 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.
送电后，CI 910F总线模板开始自检。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。

CAN Bus connector
CAN总线连接器
The CAN Bus connector of CI 910F features the following pin assignment:
CI910D的CAN总线连接器针脚分配如下
3.3.2 Connection of Freelance I/O racks
与Freelance IO机架的连接
When connecting the AC 900F controller to a Freelance rack, you have to remove the DCP 02/10 CPU modules
当AC900F控制器连接freelance机架时，你必须拆除DCP 02/10 CPU模块
For detailed information about the accessories, e.g.regarding their function, pin assignment, wire color, cable length etc. please refer to Section 4, Accessories
有关附件的详细信息，如功能、引脚等配线、电线颜色、电缆长度等请参阅第4节附件。
AC 900F controller at the beginning (end) of the CAN Bus
AC 900F控制器在CAN总线首尾
The TP 910F CAN Bus termination plug is used for terminating the three CAN busses directly at the controller at the beginning (end) of the bus lines. The open end of the TK 811F CAN cable is connected to the screw terminals of the TP 910F plug.
TP 910F CAN总线终端插头用于终止控制器的三个CAN总线线路首尾位置。TK 811F CAN电缆连接到TP 910F插头的螺丝端子上。
Redundant AC 900F controller at the beginning (end) of the CAN Bus
冗余的AC900F控制器在ACN总线的首尾
The terminating resistors integrated into the TP 910F termination plug ensure that the termination and, thus, the function of the three CAN Bus lines is preserved even if a CAN bus module or ontroller is replaced. TB 870F is used for connecting the CAN bus between controllers and to the I/O rack。
终端电阻集成在TP 910F终端插头上，以确保三条CAN总线终端功能，甚至一个CAN总线模板或者控制器模板被替换（也能正常）。TB 870用于连接控制器和IO机架之间的CAN总线。

The TK 831F cable contains feed and return lines. When replacing a CI 910F
module or controller, only disconnect the 9-pole connector. Disconnecting the
25-pole connector will interrupt the CAN Bus.
TK 831F线缆包含来回线路。当替换CI 910F模板或者控制器时，只需要断开9针插头。断开25针连接器将中断CAN总线。
