Certain events and handling of the controller system result in clearing the RAM (set to zero).
A total RAM backup (DUAP/LOAP) is needed to restore the memory. Or a backup of the
application on flash memory card can be used. The latter feature was introduced by product
release 1.2. Table 2-15 shows the situations which result i clearing the RAM.
NOTE
The listed situations in Table 2-15, besides clearing the RAM, automatically:
1. Boot the system.
2. Load system software from the system program card (backup).
3. Alternatively
a. Set the controller in working mode CONFIGURATION, ready for application
program load, LOAP, from an engineering station.
b. Or, if an optional application program card (backup) is available, load the application
software ending up in the working mode prevailing when the backup was created.
For example working mode OPERATION.

(1) DUTDB/LOTDB is sometimes a faster alternative than source code handling (source code is always possible). The compatibility code
for the data base of the system software decides.
Possible causes of non-compatibility (and need of source code) are: new release, revision, changed mix of optional program modules.
(2) PC program source code is transferable between different Advant Controllers provided that the PC elements exist in the system in
which the dump is to be loaded.
