NI PXIe-7965R数据采集CPU串行端口信息电源上的串行端口连接器访问CPU串行端口，这是所有Series 90-30 CPU的一项功能。请参阅第5章“CPU”了解RAM存储器备用电池（所有电源）用于维护CPU中CMOS RAM存储器内容的长寿命锂电池（IC693ACC30）可通过卸下电源面板底部的盖板进行访问。该电池安装在一个塑料夹子上，NI PXIe-7965R数据采集该夹子固定在该盖子的内侧。电池连接到一个小型Berg母连接器，该连接器连接到安装在电源印刷电路板上的两个Berg公连接器中的任何一个。该电池可以用PLC的电源更换。如果出现电池电量不足警告（BATT LED亮起），请在从机架上卸下电源之前更换电源中的电池。否则，数据可能会损坏或应用程序将从内存中清除。其他电池信息有关内存备用电池的其他信息，请参阅“内存备用和备用电池”一章NI PXIe-7965R数据采集
英文资料
CPU Serial Port Information The serial port connector on the power supply accesses the CPU serial port, which is a feature of all Series 90-30 CPUs. See Chapter 5, “CPUs” for information Backup Battery for RAM Memory (All Supplies) The long-life Lithium battery (IC693ACC30) used to maintain the contents of the CMOS RAM memory in the CPU is accessed by removing the cover plate located at the bottom of the power supply faceplate. This battery is mounted on a plastic clip attached to the inside of this cover. The battery is wired to a small Berg female connector that connects to either of the two Berg male connectors mounted on the Power Supply printed circuit board. This battery can be replaced with power applied to the PLC.If a Low Battery Warning (BATT LED turns ON) occurs, replace the battery located in the power supply before removing power from the rack. Otherwise, there is a possibility that data will be corrupted or the application program will be cleared from memory. Additional Battery Information For NI PXIe-7965R数据采集dditional information on the memory backup battery, see the chapter, “Memory Backup and Backup Battery.”
