2.产 品 详 情 资 料：
NI PXIe-5601变频器模块必须注意满足共模电压规格。超过规定值的共模条件将导致传输错误和/或90系列PLC组件损坏。当超过共模电压规格时，必须使用端口隔离器，NI PXIe-5601。有关此端口隔离器的详细信息，请参阅附录E。电缆和连接器规格电缆组件是通信故障的最常见原因之一。为了获得最佳性能，请根据推荐的连接器零件和规格构造电缆组件。Series 90 PLC串行端口Series 90 PLC串口与RS-422兼容。RS-232到RS-422转换器需要连接到提供RS-232兼容接口的系统。Series 90 PLC RS-422串行端口为SNP通信提供物理连接。该端口是一个5针D型阴连接器，位于如下位置：显示了90系列PLC类型的串行端口方向和连接器布局。NI PXIe-5601CPU上的连接器方向从Series 90-30连接器旋转90度，引脚位于右上方。）NI PXIe-5601表A-2显示了适用于两个PLC的引脚编号和信号分配。
Care must be taken that common mode voltage specifications are met. Common mode conditions that exceed those specified will result in errors in transmission and/or damage to Series 90 PLC components. When the common mode voltage specification is exceeded, a port isolator such as theNI PXIe-5601 must be used. See Appendix E for details on this port isolator.Cable and Connector Specifications The cable assembly presents one of the most common causes of communication failure. NI PXIe-5601For best performance construct the cable assemblies according to the recommended connector parts and specifications.Series 90 PLC Serial Port The Series 90 PLC serial port is compatible with RS-422. An RS-232 to RS-422 converter is required to interface to systems that provide RS-232 compatible interfaces. The Series 90 PLC RS-422 serial port provides the physical connection for SNP communication. This port is a 5-pin D-type female connector located as follows:shows the serial port orientation and connector layout for the Series 90 PLC types. (The orientation of the connector on the Series 90-20 CPU is rotated 90 degrees from the Series 90-30 connector with pin to the upper right.) Table A-2 shows the pin numbering and signal assignment applicable to both PLCs.
