如果使用此电缆，则不会安装单独的终端接线盒。警告：I/O总线扩展电缆不应与I/O扩展底板的电源连接或断开。可能会导致意外的PLC操作。电缆应用建议一般来说，在可能的情况下，使用标准的工厂制造电缆是有利的，以节省时间并避免布线错误。当标准长度（0.5、1、2、8或15米）适合需要时，使用标准电缆连接同一机柜中的底板（CPU和扩展底板之间、两个扩展底板之间或两个远程底板之间）。作为定制点到点电缆的Y形跳线（IC693CBL300通常用于此）。这种组合节省了时间，因为点对点电缆的构建速度比Y形电缆快得多。如图10-23所示。当您不需要电缆长度时，使用定制电缆
If this cable is used, you would not install a separate terminator block. Caution I/O Bus Expansion cables should NOT be connected or disconnected with power applied to the I/O expansion baseplate(s). Unexpected PLC operation may result. Cable Application Suggestions In general, it is advantageous to use standard, factory-built cables, where possible, to save time and avoid wiring errors. Using Standard Cables For connecting between baseplates (either between a CPU and expansion baseplate, between two expansion baseplates or between two remote baseplates) in the same cabinet when a standard length (0.5, 1, 2, 8, or 15 meters) will fit the need. As a Wye jumper for custom built point-to-point cables (IC693CBL300 is often used for this). This combination saves time since a point-to-point cable can be built much faster than a Wye cable. An example of this is shown in Figure 10-23. Using Custom Built cables When you need a cable length not
