Boundary conditions
3.1 Transition to newer NCK versions (840D)
3.1.1 Create backup archive
Standard
Creating an archive to backup user data as a default action is described in:
References:
/IAD/ Startup Manual 840D/SIMODRIVE 611D: "Data Backup" section
Optimized
Data backup with optimization of the static NC memory usage is only necessary if an archive
for an NCK Version 6.3.xx is being used and the static NC memory usage needs to be
optimized.
The following memory configuration machine data is to be reset to enable the static NC
memory previously explicitly requested for technology functions:
MD18238 $MN_MM_CC_MD_MEM_SIZE = 1
An explicit request no longer has to be sent to the static NC memory as the technology
functions loaded via ELF files will request the required static NC memory on a function-
specific basis from the NC memory management.
Resetting the above machine data will reorganize the static NC memory the next time the
NCK starts up and all user data will be lost.
In this state, you must create a new archive BEFORE resetting the NCK.
Work through the following points in the sections from "Insert new PC card" to "Load
converted archive" in order.
3.1.2 Insert new PC card
Proceed as follows
1. Replace the previous PC card with the one with the new system.
2. Activate erasing the static NC memory using:
20
NCU RESET with NCU switch S3 to position 1
After this start-up, alarm 4060 "standard machine data loaded" is present.
