PROBLEM TO BE SOLVED: To satisfactorily perform communication when abnormality occurs in a path without preparing a plurality of communicable paths in a certain communication system in communication equipment capable of performing communication via a plurality of paths.SOLUTION: In a communication system, an Ethernet switch a10 is connected to a plurality of communication lines for performing communication in different communication systems, and configured to be communicable with the other communication equipment in each communication system. Then, the Ethernet switch a10 is configured to determine whether or not communication abnormality has occurred in transmission data transmitted in a certain communication system (S150), and to, when the determining that the abnormality has occurred, convert the transmission data in which the communication abnormality has occurred into corresponding data corresponding to the other communication different from the certain communication system (S160, S170), and to transmit the corresponding data in the other communication system by using a CAN transceiver 12 (S180).SELECTED DRAWING: Figure 2 |
