<p>PROBLEM TO BE SOLVED: To reduce storage capacity for messages in a communication node.SOLUTION: A communication system including a plurality of communication nodes connected via a communication bus includes: a first communication node that creates a first data frame including an operation confirmation message to check the operation of a communication node and a first ID, creates a second data frame including the first data frame and a second ID, and transmits the second data frame to the communication bus; and a second communication node that performs control to determine whether or not the second data frame is destined to the second communication node on the basis of the second ID included in the second data frame from the first communication node, and if it is determined that the second data frame is destined to the second communication node, to create a response signal to the second data frame, and to transmit the response signal to the first communication node.</p> |
