<p><P>PROBLEM TO BE SOLVED: To acquire normal data in a short period of time by inexpensive components when disturbances such as power supply variations in reception node occur in a communication system, in which redundant data communication is performed between nodes while utilizing two physical lines. <P>SOLUTION: A transmission control means 111 of a first communication device 101 transmits first transmission data to a first line 103. A first delay means 112 delays the first transmission data by a prescribed time so as to transmit the delayed transmission data to a second line 104 as second transmission data. A second delay means 121 of a second communication device 102 delays the first transmission data input from the first line 103 by the prescribed time so as to output delayed reception data. A reception control means 122 selects either of the second transmission data input from the second line 104 and the delayed reception data output from the second delay means 121 so as to output it. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
