Upgrade Sinamics version

 Hi

How I can upgrade sinamics version ? I want to use an old version with sinumerik 828D but I think it is not supported by it because alarm 230052 show that it need to upgrade :                  230052 <location>EEPROM data error        ......    <<The following applies for CU31x and CUA31:
Update the firmware \SIEMENS\SINAMICS\CODE\SAC\cu31xi.ufw (cua31.ufw)>> .

I think last time it is used by sinumerik 802Dsl.

Thanks a lot

Hello,

When using S120 V2.6.1 (V02.60.35.00), I notice a problem that the CU320 is not running up when the DCC-technology library is loaded. Power up - power down is not a solution. A komplete re-installation of the Kompakt Flash is a solution, but the problem occurs again sporadically when the power is switched off and switched on again.
At this moment, the units are being tested without DCC-library.
At the moment of the problem, there is no communication possible by Profibus.
The LED-conditions on the CU320 are RDY = orange and DP = red. On the AOP30, the message 'waiting for communication' stays active.

Anybody experienced already this problem ?
