<p>PURPOSE:To realize a real time property sequence control which is required in an industrial control computer system, by coupling tightly a general purpose microprocessor and a sequencer. CONSTITUTION:An interface 21 provided with a general purpose memory with an interruption is provided with a general purpose 2-port memory 22 and interruption stating circuits 23, 25. This memory 22 is brought to an access by a general purpose microprocessor 9 and a sequencer 10, respectively. Also, the starting circuit 23, 25 can execute mutually an interruption start by the processor 9 and the sequencer 10. Since the interface 21 is formed in this way, the processor 9 and the sequencer 10 can be coupled tightly. Accordingly, a real time property which is required for an industrial control computer system can be satisfied.</p> |
