$AC_BLOCKTYPE
Value Meaning: Current block has been gener‐
ated because of ...
10 Pole handling with orientation transforma‐
tion
$AC_SPLITBLOCK
The system variable $AC_SPLITBLOCK can be used to determine whether an internally
generated block or a programmed block shortened by the NC is present.
$AC_SPLITBLOCK
Value
Example
Synchronized actions for counting smoothing blocks.
The query of the system variable $AC_TIMEC == 0 (interpolation cycles since start of the block)
ensures that the block type is determined only once at the start of the block.

Meaning:
0 Programmed block. A block generated by the compressor is also treated as a programmed
block.
1 Internally generated block or a shortened original block
3 Last block in a chain of internally generated blocks or shortened original blocks
$AC_MARKER[0] = $AC_MARKER[0] + 1
$AC_MARKER[1] = $AC_MARKER[1]+1
$AC_MARKER[2] = $AC_MARKER[2] + 1
