我公司很多机器控制用的是CPU-315-2DP,我对程序作了备份.但有两台机器我用Upload station下载时,先提示:(2000) Error while uploading the configuration to the programming device(PG).
Do you want to continue?
确认后提示:(120) Error while uploading the configuration to the programming device(PG).
下载完后检查发现程序块全部有,但硬件组态信息不全,只有CPU主站和其中一个子站的硬件组态信息.
查帮助引起原因和解决办法提示为:
Cause:

:Inconsistent hardware configuration in the module
(occurs if downloading the SDBs to the module was already incomplete or inconsistent)

:The optional package for configuring certain modules (for example, CPs) is not installed

:The module was configured with a later version or STEP 7, and the current version of STEP 7 cannot interpret the SDBs.

To Correct or Avoid Error:

You can decide whether to continue or abort processing.
Ensure that all software packages required for configuring the station are installed on your programming device.
Ensure that you have a STEP 7 version that can be used to configured all modules.

In either case you must remember that the hardware configuration uploaded to the programming device may be incomplete or inconsistent.

我都试过了,还是不行.不知道何原因引起.各位高手帮帮忙,如何解决?
