英文資料
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數(shù)據(jù)采集dditional information on the memory backup battery, see the chapter, “Memory Backup and Backup Battery.”
