    摘要: A PLC apparatus that performs operation processing of a sequence program using a micro-processor. The PLC apparatus has a PLC control unit (10) and a high-speed input/output module (20) that performs logic operation at high speeds in response to input signals from an external unit and that produces the result of logic operation to an external unit. Therefore, external signals can be processed at high speeds without the need for any particular processor.
