If CTABDEL is programmed without specification of the curve table to be deleted, then all curve
tables or all curve tables in the specified memory will be deleted:
CTABDEL(): Deletes all curve tables in the static and the dynamic NC memory
CTABDEL(,,"SRAM"): Deletes all curve tables in the static NC memory
CTABDEL(,,"DRAM"): Deletes all curve tables in the dynamic NC memory
Note
If, in the case of multiple deletion with CTABDEL(<n>,<m>) or CTABDEL(), at least one of the
of the curve tables to be deleted is active in a coupling, the delete command will not be
executed; in other words, none of the addressed curve tables will be deleted.
3.16.2.4 Locking curve tables to prevent deletion and overwriting (CTABLOCK, CTABUNLOCK)
Locks can be set to protect curve tables against unintentional deletion and overwriting. Once
a lock has been set, it can be revoked at any time.
Syntax
Lock:
CTABLOCK(<n>)
CTABLOCK(<n>,<m>)
CTABLOCK(<n>,<m>,<memory location>)
CTABLOCK()
CTABLOCK(,,<memory location>)
Unlock:
CTABUNLOCK(<n>)
CTABUNLOCK(<n>,<m>)
CTABUNLOCK(<n>,<m>,<memory location>)
CTABUNLOCK()
CTABUNLOCK(,,<memory location>)
Meaning
CTABLOCK: Command for setting a lock to prevent deletion/overwriting
CTABUNLOCK: Command for revoking a lock to prevent deletion/overwriting
CTABUNLOCK unlocks the curve tables locked with CTABLOCK. Curve tables
which are involved in an active coupling remain locked and cannot be deleted.
The lock with CTABLOCK is unlocked as soon as the lock applied due to the
active coupling is unlocked when the coupling is deactivated. This table can
therefore be deleted. It is not necessary to call CTABUNLOCK again.
<n>: Number (ID) of the curve table to be locked/unlocked
When a curve table range CTABLOCK(<n>,<m>)/CTABUNLOCK(<n>,<m>)
is locked/unlocked, <n> is used to specify the number of the first curve table
in the range.
