Motion synchronous actions
10.3 Main run variables for synchronized actions
Note
$AC_BLOCKTYPEINFO also always includes the value for the block type in the thousands
position (T) in the case that there is an intermediate block. The thousands position is not
accepted in $AC_BLOCKTYPE not equal to 0.
$AC_SPLITBLOCK
Value:
0
1
3
Example: Counting blending blocks
Program code
$AC_MARKER[0]=0
$AC_MARKER[1]=0
$AC_MARKER[2]=0
...
ID=1 WHENEVER ($AC_TIMEC==0) AND ($AC_BLOCKTYPE==5) DO $AC_MARKER[0]=$AC_MARKER[0]+1
...
ID=2 WHENEVER ($AC_TIMEC==0) AND ($AC_BLOCKTYPEINFO==5001) DO $AC_MARKER[1]=$AC_MARKER[1]+1
ID=3 WHENEVER ($AC_TIMEC==0) AND ($AC_BLOCKTYPEINFO==5002) DO $AC_MARKER[2]=$AC_MARKER[2]+1
...

Significance:
Unchanged programmed block (a block generated by the compressor is also dealt with as
a programmed block)
There is an internally generated block or a shortened original block
The last block in a chain of internally generated blocks or shortened original blocks is
available
Comments
; Definition of synchronized actions with which
blending blocks are counted.
; All blending blocks are counted in $AC_MARKER[0]:
; Blending blocks generated with G641 are counted in $AC_MARKER[1]:
; Blending blocks generated with G642 are counted in $AC_MARKER[2]:
