ZYGO 7714激光干涉头这种不断变化的数据不会自动复制到PROM设备。它只存在于RAM内存中。因此，如果断电且没有RAM内存备用电池，则数据将丢失。然而，在无电池系统中保存数据的一种方法是通过网络将数据发送到可以将数据存储在硬盘上的计算机。此外，RAM存储器中包含的静态数据（不变的数据），例如数学常数或查找表类型信息，ZYGO 7714可以最初存储在PROM中，并在每次PLC通电时自动写入RAM。另一个考虑因素是，如果您更改了程序（或配置），某人必须记住将更改的信息写入PROM设备。如果忘记了该步骤，则更改仅存在于RAM内存中，而在无电池系统中，下次从PLC断电时，更改将丢失。配置无电池系统以下是配置系统以无电池运行的基本步骤。当以这种方式配置时，每次PLC通电时，PROM存储器的内容将写入RAM存储器。ZYGO 7714
ZYGO 7714This constantly changing data is not being copied automatically to the PROM device. It only exists in RAM memory. Therefore, if power is lost and there is no RAM memory backup battery, this data will be lost. However, one way to preserve data in a battery-less system is to send it over a network to a computer that can store the data on its hard drive. Also, static data (data that doesn’t change) contained in RAM memory, such as mathematical constants or look-up table type information, can be stored initially in PROM and automatically written back to RAM each time the PLC powers up. Another consideration is that if you change your program (or configuration), someone will have to remember to write the changed information to the PROM device. If that step is forgotten, the change only exists in RAM memory, and in a battery-less system, it will be lost the next time power is removed from the PLC.Configuring a Battery-Less System Here are the basic steps to configure a system to run battery-less. When configured this way, the contents of PROM memory will be written into RAM memory each time the PLC powers up.ZYGO 7714
