$AC_MARKER[<arithmetic_expression>] (int) Flag variables: can be used to build complex
conditions in synchronous actions:
8 Markers (Index 0 - 7) are available.
Reset sets the markers to 0.
Example:
WHEN .....DO $AC_MARKER[0]=2
WHEN .....DO $AC_MARKER[0]=3
WHEN $AC_MARKER[0]==3 DO $AC_OVR=50
Can be read and written independently of
synchronous actions in the parts program:
IF $AC_MARKER == 4 GOTOF SPRUNG
$AC_PARAM[<arithmetic_expression>] (real) Floating-decimal parameter for synchronous
actions. Serves as intermediate saving and
evaluation in synchronous actions.
50 Parameters (Index 0 - 49) are available.
$AA_OSCILL_REVERSE_POS1
[<axial expression>] (real)
$AA_OSCILL_REVERSE_POS2
[<axial expression>] (real)
current oscillation reversal points 1 and 2:
The current setting data from
$SA_OSCILL_REVERSE_POS1 or
$SA_OSCILL_REVERSE_POS2 is read.
This enables setting data changes at the reversal
positions during active oscillation, i.e. during an
active synchronous action.
Conditions
Conditions for motion-synchronous actions are formulated:
