Abstract:
A control system for processing machinery, the control system comprising:a sequencer connected to at least one processing machine, said sequencer including a first bus having a first bus specification defining a first bus width, a first data transmission width, a first transmission unit size, a first synchronous mode, a first signal level and a first transmission timing;a controller for controlling said sequencer, said controller including a second bus having a second bus specification defining a second bus width, a second data transmission width, a second transmission unit size, a second synchronous mode, a second signal level and a second transmission timing; andbus conversion means for converting signals corresponding to said second bus into signals corresponding to said first bus when a difference exists between said first bus specification and said second bus specification, said bus conversion means including a signal conversion means for receiving signals on the second bus, adjusting timing and levels of the received signals, and outputting the adjusted signals to the first bus.
