INDUSTRIAL CONTROLLER APPARATUS CAPABLE OF LOW ERROR, ULTRA HIGH-SPEED SERIAL COMMUNICATION AND METHOD FOR DRIVING SAME

摘要

Disclosed herein are an industrial controller device and a method of driving the same. The industrial controller includes a control unit, a first optical transmission/reception unit, a second optical transmission/reception unit, and a switching unit. The control unit handles a downlink transmission frame depending on whether or not the Protocol Control Information (PCI) of the downlink transmission frame corresponds to an ID of an industrial controller device, and internally generates and outputs an uplink transmission frame. The first optical transmission/reception unit externally sends or receives the uplink or downlink transmission frame. The second optical transmission/reception unit has at least one port, and externally sends or receives the uplink or downlink transmission frame. The switching unit sequentially transfers the downlink and uplink transmission frames, transfers the uplink transmission frame to the first optical transmission/reception unit, and transfers the downlink transmission frame to the second optical transmission/reception unit.
