Startup after replacement of the PCU or the MCI board

If, during booting, it has been ascertained that both the SRAM image on the PCU hard disk

and the MCI board SRAM have buffered valid, but different user data (both components

were already in use in one SINUMERIK 840Disl), no automatic selection can be made.

The user must decide through the following message box, which user data are to be used

If a backup copy (Ghost image) of a previously booted SINUMERIK 840Di sl is loaded into

the PCU again, the user data buffered in the SRAM of the MCI board will be used again.

The SINUMERIK 840Di sl is thus ready again immediately.
