The following illustration shows two examples of the combination of a
MC_MoveAbsolute and an MC_MoveAddititve module.
 The left part (a) of the time diagram shows a case in which the second function
module is executed after the first function module.
After the first function module has traveled to Position 60, the "Done" output gives
the execution command to the second FB, which then moves on another 40 units
 The right part (b) of the diagram shows a case in which the second function
module is activated while the first FB is being executed. Because the second
module is started during the execution of the first FB, the first FB is automatically
interrupted.
The second function module adds the missing units that are still lacking for the
first module and the moves an additional 40 units with the new predefined
settings.
