NI PXIe-8130嵌入式控制器中文資料：
NI PXIe-8130嵌入式控制器在嵌入式CPU型號中，RAM內存安裝在背板上。在模塊化CPU型號中，RAM內存安裝在CPU模塊內。備用電池通常用于在電源關(guān)閉時(shí)保存RAM內存的內容。RAM內存備份/備用電池信息請參閱第6章了解以下信息：?RAM內存備份建議。?備用電池信息，如估計壽命、NI PXIe-8130更換、使用日期代碼確定電池壽命等。?低電量警告方法?？删幊讨蛔x存儲器（PROM）類(lèi)型90-30系列CPU中使用三種類(lèi)型的PROM設備：EPROM：可擦除可編程只讀內存。它是一種插入式集成電路存儲設備，可以用紫外光擦除。EPROM安裝在PLC中時(shí)可以讀取，但為了向其寫(xiě)入新數據，必須將其從PLC中移除，并使用外部PROM燒錄設備寫(xiě)入。NI PXIe-8130
英文資料
In the embedded CPU models, RAM memory is mounted on the backplane board. In the modular CPU models, RAM memory is mounted inside the CPU module. A backup battery is usually used to preserve the contents of RAM memory when power is off. RAM Memory Backup/Backup Battery Information Please see Chapter 6 for the following information: ? RAM memory backup recommendations. ? Backup battery information such as estimated life, replacing, determining battery age using date codes, etc. ? Running without a backup battery. ? Low battery warning methods. Programmable Read-Only Memory (PROM) Types There are three types of PROM devices used in Series 90-30 CPUs: EPROM: Erasable Programmable Read-Only Memory. It is a plug-in integrated circuit memory device that can be erased with an ultraviolet light. EPROMs can be read when installed in the PLC, however in order to write new data to them, they must be removed from the PLC and written to using an external PROM burning device.NI PXIe-8130
