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。

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

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。
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. |
