master user-set allocations until the scan
list is cleared, regardless of whether the
power is turned OFF and back ON again.

Returns to FALSE when the scan list is
registered and the Unit starts operating
with the scan list enabled.
Note
If there is a setting information error,
an error code will be stored in
*_MstrAlocTblCfgSta (Setting Results
of Master User-set Allocations Setup)
and *_Mstr1SListRegErr (Scan List
Register/Clear Failed) will change to
TRUE.
