Processing of synchronized actions
Synchronized actions are checked in the interpolation cycle to determine whether they
contain actions to be activated.
Action(s) are executed in synchronism with path control if the preconditions programmed on
the left of the action(s) are fulfilled.
Order of execution
Within an interpolation cycle, modal synchronized action instructions are processed in order
of their ID number (i.e. block with ID number 1 before block with ID number 2, etc.). Once the
modal synchronized action instructions have been executed, non-modal synchronized action
instructions are processed in the order in which they are programmed.
