10.1.5 Overview of synchronized actions

SW 3.x and lower
• Programming of sequences in the interpolation
cycle at the user level (part program)
• Response to events/statuses in the interpolation
cycle
• Gating logic in real time
• Access to I/Os, control status and machine status
• Programming of cyclic sequences that are
executed in the interpolation cycle
• Triggering of specific NC functions (read-in
disable, axially overlaid motion, ...)
• Execution of technology functions in parallel with
path motion
• Triggering of technology functions regardless of
block boundaries
SW 4 and higher
• Diagnosis possible for synchronized actions
• Expansion of the main run variable used in
synchronized actions
• Complex conditions in synchronized actions
• Expansion of expressions in synchronized
actions:
Combination of real-time variables with basic
arithmetic operations and functions in the
interpolation cycle, indirect addressing of main
run variables via index can be changed online
Setting data from synchronized actions can be
modified and evaluated online
• Configuration possibilities: Number of
simultaneously active synchronized actions can
be set via machine data.
• Start positioning axis motion and spindles from
synchronized actions
(command axes)
• Preset from synchronized actions
