<p>PURPOSE: To increase the control speed and to improve the general usefulness without requiring the design change by constituting the control part of a programmable logic which has an instruction, which operates an operation part, as a logic of hardware. CONSTITUTION: The programmable logic constituting a control part 24 has instructions for individual sequence control of operation parts 21 and 22, an another processing part 23, and external devices 31 to 36 and instructions required for the interface action of external pins 26 to 28 and an external bus 29 as logics of hardware. Therefore, the individual sequence control of operation parts 21 and 22, the another processing part 23, and external devices 31 to 36 is performed without requiring read and decoding of a control program from the outside. Consequently, the control speed is increased by omission of read and decoding of the control program and parallel execution of the sequence control.</p> |
