<P>PROBLEM TO BE SOLVED: To execute the confirmation of the soundness of an application program and to improve maintainability, without performing such an operation as power supply or connecting such a device as a maintenance tool to a control device. <P>SOLUTION: This information processor is provided with: a storage part for storing an application program acquired from the outside; a temporary storage part in which the application program read from the storage part is developed; a clock part for clocking a time; and an arithmetic processing part. The above mentioned arithmetic processing part executes the application program developed in the temporary storage part, and collates the application program stored in the storage part with the content of the application program developed in the temporary storage part in the spare time of an arithmetic processing time relating to the execution of the application program developed in the temporary storage part, and stores the result of collation in association with the time information in collation acquired from the clock part in the storage part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
