COMMUNICATION METHOD OF A GATEWAY DEVICE AND A GATEWAY DEVICE USING THE SAME FOR SUPPORTING COMMUNICATION WITH A CONTROL AREA NETWORK AND A MODBUS CAPABLE OF REDUCING COSTS FOR ADDING A DEVICE COMMUNICATION PROTOCOL OR SOFTWARE

摘要

PURPOSE: A communication method of a gateway device and a gateway device using the same are provided to use software and the device without changing or modifying Modbus software.;CONSTITUTION: A CAN(Controller Area Network) inputting unit(41) receives a CAN input data frame. A Modbus inputting unit(44) receives a Modbus input data frame. A converting unit(34) converts the received CAN input data frame into a Modbus output data frame. The converting unit converts the received CAN input data frame into a CAN output data frame. An output unit outputs the converted Modbus output data.;COPYRIGHT KIPO 2013;[Reference numerals] (34) Converting unit; (41) First input unit; (42) First output unit; (43) Second output unit; (44) Second Input unit; (AA, CC) CAN data; (BB, DD) MODBUS data
