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。

LED LED灯	COLOR 颜色	STSTUS 状态	Meaning 含义
PWR 电源	Green 绿色	ON 亮	Module in operation and must not be removed  模板在用，不能拆除
		OFF 灭	Module not in operation and may be removed, if required 模板没有使用，如有需求，可以拆除
STA 状态	Green 绿色	ON 亮	Active module operating properly 活动的模板正常运行
		OFF 灭	Module start-up 模块启动
	Orange 橙色	ON 亮	Module identified by the CPU module, but inactive CPU识别出模块，但模块没有运行
	Red 红色	off 灭	Module under power, but not yet identified or module failure 模块送电，但是没有识别出来，或者模块故障
L1	Green 橙色	ON 亮	Communication on CAN 1 channel  使用CAN 1通道通讯
		OFF 灭	No communication 没有通讯
	Yellow 黄色	Flashing 闪烁	Sporadic transmission error 零星传输错误
	Red 红色	Flashing 闪烁	Transmission interrupted (bus off mode) 传输中断（总线关闭模式）
L2	Green 橙色	ON 亮	Communication on CAN 2 channel  使用CAN 2通道通讯
		OFF 灭	No communication 没有通讯
	Yellow 黄色	Flashing 闪烁	Sporadic transmission error 零星传输错误
	Red 红色	Flashing 闪烁	Transmission interrupted (bus off mode) 传输中断（总线关闭模式）
L3	Green 橙色	ON 亮	Communication on CAN 3 channel  使用CAN 3通道通讯
		OFF 灭	No communication 没有通讯
	Yellow 黄色	Flashing 闪烁	Sporadic transmission error 零星传输错误
	Red 红色	Flashing 闪烁	Transmission interrupted (bus off mode) 传输中断（总线关闭模式）

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。
