To attain reduction of necessity of a controller memory by generating an instantiated version of a control routine and controlling a unit module by performance of instantiated version of a general control routine.
In a controller 12, a unit object indicates a phase theory which is independently operated by the controller 12 on a unit module and is potentially in parallel to other active unit phases simultaneously on a different unit module. A unit phase object is one instantiated version of a phase class which is decided by using an areas decision table for the unit module to which the unit phase object belongs. Then, the controller 12 actually performs the unit phase object (an instantiated version of the phase class during an execution time) and leaves a general version of the phase class in a memory 22.
