REPORT SIGNAL SYSTEM FOR ABNORMALITY OCCURRENCE

摘要

PURPOSE:To directly search a trouble cause with a testing machine by outputting a signal to report the occurrence of error if time-out error or data- compare error occurs. CONSTITUTION:An instruction executing part 3 monitors the time to reception of the processing termination report after starting a line control part 9, and the part 3 outputs a time-out signal to set an FF 12 if the report is not received over a preliminarily determined time. Then, an interrupt time-out signal is outputted from a terminal 14. Data transmitted to the transmission side of the control part 9 and data received in the reception side by data turning-back are compared with each other by a test program. If they do not coincide with each other, the executing part 3 outputs data-compare error to set an FF 11. Then, a data-compare error signal is outputted from a terminal 15. Thus, the trouble cause is directly searched by the testing machine.
