Cannot be detected in the procedure of information communication between the transmission device 1 and the reception device 2, and the reception device 2 performs predetermined information processing on the incorrect transmission information.

For this reason, for example, in a database system, when new information is created by transmission information and the previous and subsequent relationships are lost, that is, the information stored in the database is divided and new registration is performed for each. However, if one of them is processed, even if the transmission information is retransmitted, the information in the database cannot be restored. Also, if you fall into this situation,
In addition to spending a huge amount of operation and countermeasure costs such as manually repairing the contents stored in the database of the receiving device 2 related to the transmission information, in the worst case, the operation of the system is completely stopped. Furthermore, the possibility of such a situation becomes a further concern for a person who is unfamiliar with the operation of the communication device, and becomes an alienation factor for promoting the rationalization of work by introducing the communication device.

The present invention has been made in view of the above-mentioned circumstances, and the transmission information of the transmission device received by the reception device is returned as reply information, and the transmission device receives the reply information and sets the corresponding transmission information. By comparing, an error display method for communication information is provided, which enables early detection of an error in transmission information and avoids destruction or alteration of information stored in a database or the like of a receiving device to improve operability.
