Enable/cancel blocking
The following functions can be used to enable or cancel deletion and overwrite blocks for
parts. programs.
• Enable deletion and overwrite block.
General form: CTABLOCK(n, m, memType)
• Cancel deletion and overwrite block.
CTABUNLOCK releases the tables locked with CTABLOCK. Tables involved in an active
coupling remain locked, i.e. they cannot be deleted. However, the CTABLOCK command is
cancelled, i.e. the table can be deleted as soon as the coupling is deactivated. It is not
necessary to call CTABUNLOCK again.
General form: CTABUNLOCK(n, m, memType)
Applications of the forms:
Curve table with number n
CTABLOCK(n)
Curve tables in the number range n to m.
CTABLOCK(n, m)
All curve tables, irrespective of memory type
CTABLOCK()
All curve tables in the specified memory type
CTABLOCK(, , memType)
Curve table with number n
CTABUNLOCK(n)
Curve tables in the number range n to m.
CTABUNLOCK(n, m)
All curve tables, irrespective of memory type
CTABUNLOCK()
All curve tables in the specified memory type
CTABUNLOCK(, , memType)
Other commands for calculating and differentiating between curve tables for applications for
diagnosing and optimizing the use of resources:
• Number of defined tables irrespective of memory type
CTABNO()
• Number of defined tables in SRAM or DRAM of NC memory
CTABNOMEM(memType)
• Number of possible curve tables in memory memType.
CTABFNO(memType)
