Abstract
A communication system including two communication nodes communicably connected in a full duplex communication mode via the same communication line is provided. Each of the two communication nodes includes a first processing unit configured to be able to send a predetermined monitoring frame to another communication node at predetermined intervals and to receive the predetermined monitoring frame from the other communication node at predetermined intervals; a second processing unit configured to detect a monitoring frame missing condition wherein the monitoring frame is received from the other communication node; and a third processing unit configured to switch communication with the other communication node from the full duplex communication mode to a half duplex communication mode when a predetermined condition is satisfied during communication in the full duplex communication mode wherein the predetermined condition includes a condition that the second processing unit detects the monitoring frame missing condition.
