Hello, 

I have a sinamics S120 Drive system with CU 310-dp which has been damaged. I managed to get a CU 310-2 dp as a replacement. each of the CU 310 and CU 310-2 have their own CF card. I have read that CF for CU 310-dp can't be used with CU 310-2 dp. However, the CF of CU 310-2 dp has the order number "6SL3054-6EH00-1BA0 SIMOCRANE in Drive SW 4.7 HF1". I created a new project and transfered the Drive unit from accessible nodes. then I tried to Export the Drive Object from CU 310-DP and import it to CU 310-2 DP. However It created So many errors and was a failure. BTW,  I created a new project and selected CU 310-2 DP  version 5.2 from the hardware catalog in starter, then I did the import/export and it was successful. So, my question is below:

is this CF flash card "simocrane" with a totally different firmware? 
is it possible to do any firmware update on the CF flash card "simocrane to work with my project?

I hope someone would give me an answer.

Then you dont need the Cranes Firmware.
