Detailed description
2.2 Curve tables
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.
To prevent this from happening, the curve tables concerned can be locked, using the
CTABLOCK(...) language command. In this case, it should be noted that the curve tables
concerned are then unlocked with CTABUNLOCK().
• Determine block condition
• Check whether the curve table exists
• Determine memory type of a curve table
• by an active coupling periodic
46
Table n
CTABISLOCK(n)
Result:
> 0: Table is blocked
Reason for block:
1: by CTABLOCK()
2: by an active coupling
3: by CTABLOCK()and by an active coupling
= 0: Table is not blocked
- 1: Table does not exist
CTABEXISTS(n)
Result:
1: Table exists
0: Table does not exist
CTABMEMTYP(n)
Result:
0: Table in static SRAM NC memory
1: Table in dynamic "DRAM" NC memory
-1: Table does not exist
CTABPERIOD(n)
Result:
0: Table is not periodic
1: Table is periodic in the leading axis
2: Table is periodic in the leading and following axes
-1: Table does not exist
Special functions: Axis Couplings and ESR (M3)
