Hello, this is very confuse. If you go online, have you in opened your original project? You can make a upload of you hardware configuration in a new or other project. But in this case there are no more symbol informations or your addresses and variables. There are also problems, if you go online with your original project but there are changes in the CPU-program (online) or in the project (offline). Other reason could be possible: The program in the CPU was created with a new STEP 7 version and with a CPU (and perhaps a firmware), which are not included with your STEP 7 version. In this case you have to make an update of your hardware catalog or you install the actual STEP 7 version. The actual STEP 7 version is V5.5 with SP1.
