I have D425 V4.0. I need to connect to TP1200-comfort via TIA v15. 
 I have done the following steps.
 1. I have Upgraded the Old Scout project to V5.2.
 2. I have changed the CPU version to D425-2 V4.3
 3. I have created the TIA V15 project with Device Proxy.
 4. I Initialised the device proxy with the upgraded project.
 5. I Added the HMI TP1200 comfort in the project and made the connection HMI_connection with ethernet and IP addressses.
 6. I have connected the TP1200 through Ethernet connection on the D425.
 6. I am able to see all the PLC tags in the project and able to insert HMI tags with no compile errors.
 The problem is whenever I add the Axis object data for eg. SENSOR DATA for actual position of an axis The TP1200 stops communication with the D425. All ##### in all tags. 
 D425 global device variables are displayed and communicating properly.

 How you change the CPU version to D425-2 V4.3??  

Does the hardware D425 not -2 support this firmware change?
