PURPOSE:To make the data transfer high-speed and reduce the memory capacity by connecting sequencers into a ring with a serial transmission line and performing sequence operations in sequencers synchronously with one another. CONSTITUTION:Plural sequencers are connected into a ring with the serial transmission line, and sequence operations are performed in sequencers synchronously with one another. For example, sequencers A1-A4 are connected into a ring with a serial transmission line L, and sequence operations are performed in these sequencers A1-A4 synchronously with one another. In case of the data transfer from the sequencer A1, required data is selected from sequencers A2-A4 and is received from sequencers in a transfer step n1, and data of the sequencer A1 itself is inputted in an input step n2. A sequencer program is executed in an execution step n3, and data requested from sequencers A2-A4 is outputted in an output step n4. |
