我用Step7配置网络是出现故障，不能创建SDB文件，帮助显示如下信息。可是"...\SIEMENS\STEP7\S7TMP"这个文件夹的只读属性改不了。
Des cription:
While creating the system data blocks (SDB) for the module which is the SDB receiver, an error was recognized in the programming device and processing halted.
The number of the SDB type which could not be created is shown in brackets ().

Cause:

?Inconsistent hardware configuration in the programming device.

?Missing or read-only folder "...\SIEMENS\STEP7\S7TMP" or "...\SIEMENS\SIMATIC_NCM\S7TMP".

?Missing authorization for an optional package that creates SDBs for a particular module.

Remedy:

You can decide whether to continue or abort processing.
In either case you must remember that the hardware configuration downloaded to the module or the hardware configuration saved may be incomplete or inconsistent.
We recommend the following procedure:

1. Abort processing.

2. Correct the cause of the error:

?Correct the hardware configuration.

?Remove the write-protection from the "...\SIEMENS\STEP7\S7TMP" folder or create the folder.

?Install the missing authorization.

3. Select the function again.
