There are two major considerations regarding the memory type for your application program. Since application memory is responsible for retaining a control program that will be run each day, volatility should be the prime consideration. With the loss of the program, the day’s production may be delayed or forfeited. The affects are usually costly. A second concern should be the ease of altering the program when required. Ease in altering the memory is important since the memory is ultimately involved in any interaction that goes on between you and the controller. This interaction begins with program generation and continues through with program changes, system startup, and ultimately on-line program changes.
The following discussions describe various types of memory and how their inherent characteristics affect the manner in which programmed instructions are retained or altered within the PLC. The unique needs of each application will dictate what type of memory is best suited.
Volatile memory types lose their programmed contents if all operating power is lost or removed. Like the onboard memory of personal computers, if a program file is loaded and power is lost or removed, the program will not be in the memory when power is restored. The program would have to be reloaded. With PLCs, however, volatile memories are supported by back-up batteries have operational lives of one year or more.
Nonvolatile memory types will retain their programmed contents even if operating power is completely lost. They require no type of backup. Examples of nonvolatile memory include storage media such as floppy disk, hard disk, and magnetic tape, all of which do not require power to maintain their programmed contents. However, nonvolatile memory types used in PLCs and discussed here are solid-state memories.

有两个主要因素对内存类型为您的应用程序。由于应用程序内存负责保留一个控制程序，将运行，每天的波动应该是首要考虑。随着损失的计划，当天的生产可能会延迟或没收。的影响通常是昂贵的。第二个关注的应该是易于改变计划需要时。容易改变记忆是重要的，因为内存是最终参与任何互动接着你与控制器。这种互动程序代开始，并继续通过与计划的变更，系统启动，并最终在网上程序的变化。
下面的讨论，说明不同类型的内存，以及如何影响其固有的特点的方式，程序的指示，保留或改变的公司。的独特需要每个应用将决定什么样的内存最适合。
挥发性记忆体类型失去其方案的内容，如果所有的业务权力丢失或删除。如板载内存的个人电脑，如果一个程序文件被加载和电力丢失或删除，该程序将无法在内存动力恢复时。该计划将不得不重新载入。与PLC的，但是，性存储器支持的后备电池业务生活一年或一年以上。
非易失性内存类型将保留其方案的内容，即使经营权完全丧失。他们不需要的备份类型。非易失性存储器的例子包括存储介质如软盘，硬盘，磁带，所有这一切并不需要电力维持其方案的内容。但是，非易失性内存类型中使用的PLC和这里讨论固态存储器。 参考技术A 有两个主要因素对内存类型为您的应用程序。由于应用程序内存负责保留一个控制程序，将运行，每天的波动应该是首要考虑。随着损失的计划，当天的生产可能会延迟或没收。的影响通常是昂贵的。第二个关注的应该是易于改变计划需要时。容易改变记忆是重要的，因为内存是最终参与任何互动接着你与控制器。这种互动程序代开始，并继续通过与计划的变更，系统启动，并最终在网上程序的变化。

以下讨论描述各种类型的记忆和如何影响他们的内在特性的方式保留或更改程序指令在可编程序控制器(PLC)。每个应用程序的特殊需求,将决定什么类型的记忆是最适合。
易失性存储器类型失去他们所有的操作程序的内容如电力丢失或删除。像宇宙飞船上的记忆的个人电脑,如果一个程序文件中载入与电力丢失或移除时,这个程序将不会在我们的记忆中,当电力恢复。该计划将必须装。然而,与plc、挥发性记忆都是由后备电池运行生命的一年或更长。
非易失性存储器类型将保留他们的程序的内容,即使操作电源是完全迷失了方向。他们要求任何类型的备份。非易失性存储器的例子包括存储媒体,如软盘,硬盘,磁带,所有这一切都不需要电源,保持他们的程序的内容。然而,非易失性存储器类型用于plc和讨论的内容是固态的记忆。 参考技术C 你要翻译吗，就自己下载一个翻译软件吧，有道桌面词典
