4.2 CAN Bus accessories

CAN总线附件

Different accessories are needed, depending on the controller configuration (single/redundant) an the location where the controller is connected to the CAN bus of the Freelance I/O racks. Refer to Section 3, Modules for details about the connection variants. 

根据控制器的配置（单机/冗余）、控制器与freelance IO机架上CAN总线的连接位置，需要不同的附件。

请参阅第 3 节，模块，了解有关连接细节。

4.2.1 TP 910F CAN Bus termination plug

TP 910F CAN总线终端插头

Features

功能

• CAN Bus termination, triple 
• CAN总线终端，三重
• Integrated terminating resistors (cannot be deactivated)
• 集成终端电阻（不可停用）
• D-SUB connector, 9-pin, male (M)
• 9针连接器，公头
• 6 screw terminals
• 6颗螺丝终端
• Connection area for cable shield and strain relief
• 电缆屏蔽和应变消除区域

Use

用处

      The TP 910F termination plug serves for terminating (with correct impedance level) three CAN bus lines directly at the CI 910F CAN Bus interface module. The screw terminals in the plug allow to connect either the TK 811F open-end CAN cable or a commercial twisted-pair cable.

     TP 910F终端插头用于在CI 910F CAN bus接口模块上直接终止(使用正确的阻抗水平)三条CAN总线线。插头中的螺丝端子允许连接TK 811F开端CAN电缆或双绞线。

4.2.2 TK 811F CAN cable

TK 811F电缆

Features

功能

• Shielded twisted-pair cable
• 屏蔽对电缆
• D-SUB connector, 9-pin, male (M)
• 9针公头
• Open-end wires with wire-end sleeves
• 带线端鼻子的剥开的导线
• Cable length 3 m
• 电缆长3米

Use

用作

The TK 811F cable connects the Freelance I/O racks to the CI 910F module. The six wires and the cable shield are connected to the TP 910F terminal plug or a preceding TB 870F terminal block. The other pair of wires is cut off and should not connected

TK 811F电缆连接Freelance IO机架和CI 910F模板。六芯线和电缆保护套连接到TP 910F模板终端插头或者TB 870F前面的终端块。其他电线被切断，不应连接。

 

4.2.3 TK 831F CAN cable TK 831F CAN总线电缆 Features 功能

• Shielded twisted-pair cable
• 屏蔽双绞线电缆
• Two connectors, D-SUB 9-pin male (M) and D-SUB 25-pin female (F)
• 两个连接器，9针公头和9针母头
• Cable length 0.5 m
• 电缆长度0.5米

Use 用于      The TK 831F cable connects the CI 910F CAN module to the TB 870F terminal block. The cable is provided with a feed line and a return line for each signal in order to avoid using spurs. For example, the pins 1 and 14 of the 25-pin connector are electrically connected to pin 2 of the 9-pin connector via one wire, each.

     TK 831F 电缆将 CI 910F CAN 模块连接到 TB 870F 终端块。该电缆为每一个信号提供馈送线和回线，目的是为了避免使用激励。例如，25 针连接器的引脚 1 和 14通过一根电线将 9 针连接器的引脚 2 电连接到每个连接器。

When replacing the CI 910F module or the controller, disconnect the 9-pin connector only. Disconnecting the 25-pin connector will interrupt the CAN bus 更换 CI 910F 模块或控制器时，仅断开 9 针连接器。断开 25 针连接器将中断 CAN 总线.

4.2.4 TB 870F terminal block TB 870终端块 Features 功能

• 25-pin D-SUB plug for connecting TK 831F
• 25针插头连接TK831F
• Two terminal strips with 14 screw terminals, each
• 两个终端条，每个带 14 个螺丝终端
• DIN rail mounting  
• DIN导轨安装

Use 用于       The TB 870F terminal block connects the CAN bus of the primary controller to that of the secondary controller. It is also used to connect a controller in the middle of a CAN bus line between two I/O racks

     TB 870F 终端块将主控制器的 CAN 总线连接到辅助控制器。它还用于连接两个IO机架之间的CAN总线上的控制器。
