描述
西门子PLC模块 CPU中文本(例如报警文本)的存储空间受系统的限制，并取决于所使用的CPU类型。下表概述了每种CPU类型的报警文本的存储容量。
S7-1500 CPU 类型(> V14) 文本的可用存储空间(例如，报警文本)
S7-1510 .. S7-1513, ET 200SP, Compact CPUs 3.0 MB
S7-1515 .. S7-1516 4.5 MB
S7-1517 .. S7-1518 7.5 MB
S7-1505SP(F/T/TF),S7-1507S(F) 3.0MB
S7-1508S(F) 7.5MB
PLCSIM 7.5 MB
报警文本的存储空间用于不同的TIA Portal选项:
● 可编程的用户报警
● 程序报警
● S7-GRAPH
● ProDiag
● 系统生成的警报
● 系统诊断
● 运动控制信息
● 安全信息
● SINUMERIK 信息
目前，在TIA Portal中没有显示或信息表明内存负载的当前状态。因此，只能在下载到CPU时获得内存已满的信息。
补救措施
在下载CPU时如出现上述的错误信息，可用以下补救方法:
● 更换如上表所示的有更多报警文本内存可用的CPU。例如，从西门子PLC模块 S7-1515 CPU换到S7-1516 CPU没有区别，因为它们的报警文本存储空间相同。在这种情况下，你应该使用大一档的S7-1517 CPU。
● 在停止模式下，将西门子PLC模块 文本列表下载到CPU。如果在运行模式下将文本列表下载到CPU，则CPU会为文本更改占用额外的存储空间。更新后的文本列表中不再需要的部分只有在下载之后才会被删除。在停止模式下，删除在下载期间完成。
● 在“语言和资源>项目语言”下的项目导航中禁用不需要的项目语言。保存和编译项目，并将项目数据下载到CPU中。CPU中每个启用的语言还占用额外的存储空间。
● 通过GSD(ML)将SINAMICS驱动器作为CPU的IO设备，以减小运动消息的大小。每个驱动器在项目中既可以作为单独网络中的Startdrive对象，也可以作为项目中的GSD(ML)。GSD文件中的文本比Startdrive中的运控文本占用更少的内存空间。
● 避免使用特殊字符，因为它们会占用更多的存储空间。
● 对于Cyrillic 或far-east 字符集，一个字符***多可以占用4个字节。
● 文本列表中引用的在扩展ASCII范围内的控制字符会占用2个字符（8字节）。
