已经编好的程序,程序做了点改动(把原来的大块拆成了小块,完全是ctrl+c

ctrl+v),当我下载程序时,系统提示:

Debuggong functions are still active in the module. Blocks,in which

debugging functions are taking place , cannot be overwritten!
其detail为
Des cription of Error:

In the named module, test functions are still active (force function,

for example) that should be terminated as a precaution before

downloading. In the new configuration, for example, forced areas

could be missing, or areas could contain force values that were not

planned.

If you select Yes, the system data (SDBs) are transferred and the

undesirable reactions named above could occur. The CPU configuration

may then be inconsistent, because certain configuration data can not

be loaded! If you select No, the download will be aborted. In this

case, no system data (SDBs) will be transferred to the module or into

the station.

我选了继续(yes)

然后是一顿覆盖,然后问我是否要load sysytem data 看了detail后,

我选是,然后在覆盖时出错,提示为:

The system data cannot be loaded to module cpu 315-2 dp - (R0/S2) of

station SIMATIC 300(1) Look under detials or try to determine the

cause for th problem using the diagnostic buffer of the module

在下载程序后,SF灯亮,请问我这是硬件错误还是软件错误,怎么解决阿?

如果对错误的描述不够,大虾们提阿,我尽可能的提供.
