NI PXIe-6545 PXI数字模块串行电缆图本节仅介绍了90系列PLC的多点对点和多点串行端口连接中的一些。在点对点配置中，只有两个设备可以连接到同一通信线路。通信线路可以使用RS-232（50英尺，最大5米）或RS-485（4000英尺，最大200米）直接连接。调制解调器可用于更远的距离。NI PXIe-6545注：Series 90-70和Series 90-30 PLC串行端口的电缆连接器必须是直角连接器，以便模块上的铰链门正确关闭。请参阅表A-连接器/电缆规格。RS-422点对点连接如果您的主机设备配备了RS-422卡，NI PXIe-6545您可以直接连接到90系列PLC多点连接。在多点配置中，主机设备配置为主设备，一个或多个PLC配置为从设备。
Serial Cable Diagrams This section describes only a few of the many and various Point-to-Point, and Multidrop serial port connections for Series 90 PLCs. In the point-to-point configuration only two devices can be connected to the same communication line. The communication line can be directly connected using RS-232 (50 feet, NI PXIe-65455 meters maximum) or RS-485 (4000 feet, NI PXIe-6545200 meters maximum). Modems can be used for longer distances. Note The cable connector for the Series 90-70 and Series 90-30 PLCs serial port must be a right angle connector in order for the hinged door on the module to close properly. Refer to Table A- Connector/Cable Specification.RS-422 Point-to-Point Connection If your host device is equipped with a RS-422 card you can connect directly to Series 90 PLC Multidrop Connections In the multidrop configuration, the host device is configured as the master and one or more PLCs are configured as slaves.NI PXIe-6545
