14.2 Curve tables
a) Curve tables
● Determine total number of defined tables.
The definition applies to all memory types (see also CTABNOMEM)
CTABNO()
● Number of defined tables in SRAM or DRAM of NC memory.
CTABNOMEM (memType)
If memType is not specified, the memory type specified in the following machine data:
MD20905 $MC_CTAB_DEFAULT_MEMORY_TYPE (default memory type for curve tables)
Result:
>= 0: Number of defined curve tables
-2: Invalid memory type
● Determine number of curve tables still possible in memory.
CTABFNO(memType)
If memType is not specified, the memory type specified in the following machine data:
MD220905 $MC_CTAB_DEFAULT_MEMORY_TYPE
Result:
>= 0: Number of possible tables
-2: Invalid memory type
● Determine the table number of the pth table in the memory type specified optionally
CTABID(p, memType)
If memType is not specified, the memory type specified in the following machine data:
MD20905 $MC_CTAB_DEFAULT_MEMORY_TYPE
Result:
Table number or
Alarm for invalid p or memType
When using the CTABID(p, memType) function, no assumptions should be made
regarding the sequence of the curve tables in the memory. The CTABID(p, ...) function
supplies the ID (table number) of the curve table entered in memory as the pth curve table.
If the sequence of curve tables in memory changes between consecutive calls of
CTABID()CTABID(), e.g. due to the deletion of curve tables with CTABDEL(), the
CTABID(p, ...) function can supply a different curve table with the same number.
