<p>PROBLEM TO BE SOLVED: To improve the reliability of a data communication controller by storing operation environment detecting information outputted from an operation environment detecting computerization means in a data message so as to transmit to a receiving side computer at the time of data communication between plural computers. SOLUTION: A data communication control part 15a within a communication side computer 11a forms a communication packet storing communication control information such as address information in a communication control information field and communication data in a communication data field according to a frame format to transmit to a data communication control part 19 as the operation detecting computerization means within a routing device 17 through a data communication line 28. The data communication control part 19 reads the communication packet, analyzes temperature information signal 26 being communication control information and operation environmental information within the communication control information field and forms the communication packet again to transmit to the receiving side computer 11b through a data communication line 27. Consequently the reliability of the whole system is improved.</p> |
