各位：小弟我最近做程序时，发现一个问题，就是在硬件组态后，硬件为CPU315_2DP,CP343-2,CP343-1.进行汇编时出现错误，提示:An error ocurred creating or interprting the system SDO,the action willbe aborted.点击帮助出现以下画面。
Des cription of Error:

Error attempting to generate the configuration data.
Possible causes:

· Hard disk full

· No "...SIEMENS\STEP7\S7TMP" folder available or the folder is read-only

· "S7 Program" or "M7 Program" folder missing

· The block folder is currently being edited

· Compiling (creating the configuration data) was interrupted

To Correct or Avoid Error:

· Delete any files not required from the hard disk

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

· Recreate the "S7 Program" or "M7 Program" folder

· Stop editing of the block folder

· Reinstall STEP 7

根据帮助提示，莫非真的要重新装STEP7了吗。已确定是CP343-1方面的问题。此程序在别的电脑上汇编不出现在任何错误，而我电脑在装STEP7时没提示错误。版本为V5.4 SP1.
不知各位有没有在不重新装STEP7的前提解决些问题。小弟不胜感激！！！
