<P>PROBLEM TO BE SOLVED: To provide a communication confirmation device, a communication conformation method and a program for precisely confirming the communication state when the significance of an error which has occurred in a device to be monitored is determined based on the communication state of the device to be monitored. <P>SOLUTION: An information processor 1 is connected to a host server device 20 to which a monitor object device 10 is connected, and configured to transmit a connection request to the host server device 20, and to receive a response transmitted by the host server device 20 which has received the connection request to the monitor object device 10 for confirming a communication state of the monitor object device 10. When any error occurs in the monitor object device 10, the information processor 1 transmits the connection request to the host server device 20 two times separately in first and second transmission, and confirms the communication state of the monitor object device 10 based on whether or not the response to the connection request transmitted in the second transmission has been received. <P>COPYRIGHT: (C)2012,JPO&INPIT |
