<p><P>PROBLEM TO BE SOLVED: To provide a gateway device and a gateway method, capable of specifying the occurrence part of an abnormality caused by data repeating. <P>SOLUTION: The gateway device includes: a hardware repeating means for performing prescribed processing in data repeating processing between networks by hardware processing, to which a controller for performing prescribed control is connected; a software repeating means for performing prescribed processing in the data repeating processing between the networks by software processing; and an abnormality part specifying means for determining that the hardware repeating means is abnormal when the data repeating by the hardware is not performed for prescribed time or more and also the data repeating by the software repeating means is performed within a time shorter than the prescribed time. Consequently, it is accurately predetermined that the abnormality occurrence part is the hardware repeating means, based on a data repeating time interval in the hardware processing and a data repeating time interval in the software processing. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
