NI PXIe-5114示波器图5-3：。电源上的CPU串行端口连接器Ŷ此串行端口与RS-485兼容，并使用GE Fanuc SNP（90系列协议）协议（仅从机）。Breakfree SNP成为Series 90-30 CPU上所有串行端口的默认协议，从CPU 350–364的固件版本9.00开始，CPU 311–341的固件版本8.20开始。有关详细信息，请参见第5-13页。NI PXIe-5114Ŷ串行端口连接器仅在安装在包含CPU的基板中的电源中起作用。它在安装在扩展或远程底板中的电源上不起作用。Ŷ连接到串行端口的任何设备（使用90-30系列电源的+5 VDC电源）必须包含在最大功耗的计算中（请参阅第12章中的标题“电源负载计算”）。Ŷ所有Series 90-30 CPU都具有这种串行端口排列。351、352和363 CPU具有额外的串行端口，这将在本章稍后部分介绍。NI PXIe-5114

Figure 5-3. CPU Serial Port Connector on Power Supply Ŷ This serial port is RS-485 compatible, and uses the GE Fanuc SNP (Series Ninety Protocol) protocol (slave only). Breakfree SNP became the default protocol on all serial ports on the Series 90-30 CPUs, starting with firmware release 9.00 for CPUs 350–364, and firmware release 8.20 for CPUs 311–341. For details, see page 5-13. Ŷ The serial port connector is only functional in a power supply that is installed in a baseplate that also contains the CPU. It is not functional on a power supply that is installed in an expansion or remote baseplate. Ŷ Any device connected to the serial port that uses +5 VDC power from the Series 90-30 power supply must be included in the calculation for maximum power consumption (see the heading “Power Supply Loading Calculations” in Chapter 12). Ŷ All Series 90-30 CPUs have this serial port arrangement. The 351, 352, and 363 CPUs have additional serial ports, described in a later section of this chapter.NI PXIe-5114
