Abstract:
PURPOSE:To attain quick test conduction of a data transmitter from a test execution processor by interrupting and restarting the monitor processing to a test execution processor conducted by a normal processing processor by means of multiple address communication. CONSTITUTION:The test execution processor 11 sends a multiple address communication frame requesting the interruption of the monitor processing to the processor 11. A normal processing execution processor 12 receiving it via a data transmission line 21, data transmitters 31, 32 and a LAN transmission line 4 interrupts the monitor processing to the processor 11. Moreover, the processor 11 sends a multiple address communication frame requesting the restart of the monitor processing to the processor 11. The processor 12 receiving it by the similar path restarts the monitor processing to the processor 11.
