<p>A control system for processing machinery has at least one sequencer for processing machines to each of which at least one processing machine is connected, a controller for controlling the sequencer and a bus converter for converting signals flowing in a bus in the case where a first bus of the sequencer and a second bus of the controller are made on the basis of different specifications. In this system, even if manufactures of the controller and the sequencer are different each other, an appropriate signal conversion is performed based on difference of specifications of both buses, and therefore secure connection adapted to real time control can be obtained.</p> |
