PURPOSE:To obtain the monitor for ON-line failure tracing, by enabling to output the data monitored on line in the order of time, and measuring the time difference between the commands immediately after and before, and response time to the commands. CONSTITUTION:The synchronizing flag located at the heat of data is detected from the data on a line 3 with a line interface 42. This detected output is the interruption signal of a control section 41, which writes in the detected data in a memory section 43. In this case, at the same time or after the reception of this interruption signal, the time of a timer section 44 is read in the control section 41 for several mu seconds and written in the memory section 43. Thus, the data is output to an output section 45 in the order at time, and the time defference between the data at present and in the past can be measured. |
