<p>PURPOSE:To test a program stored in each processor online by executing an operation corresponding to test data which each processor receives through a network and transmitting the result to the network. CONSTITUTION:When a subsystem (n) transmits the test data as a message D1 to the network 100, each processor in terms of each subsystem stores the data on the message in an application buffer 18, and stands an application flag on a test flag table 17. If necessary, the processor 13 fetches data from an I/O device 10 and stores the processed result in a processed result buffer included in an application data buffer 18. When said flag stands, the processor 13 transmits data in the processed result buffer to the network 100 as a message D2. In accordance with the message D2 the subsystem (n) judges whether the subsystem is normal or not.</p> |
