PURPOSE:To correctly analyze operational conditions of systems at the time of fault occurrences under working conditions by using the titled tracer equipment for field maintenance, by dividing the tracer equipment into two sections, a unit section and a main body, and always installing the unit section in the micro- processor's application device. CONSTITUTION:Input data and sampling signals are received by a sampling section 1, and the input data are sampled then the sampled input data are stored in a trace memory 2 under a control of a trace memory section 3. Signals read out from the memory 2 are added to an interface section 7. A unit section 9 is constituted of the sampling section 1, the memory section 2, the control section 3, and the interface section 7, and the unit secton 9 is installed in an application device of a micro-processor mup. A bus signal P from the unit section 9 is input into a main body 8, and display data (m) are displayed in display section 5 under a control of a tracer control section 4 in accordance with operational data (n) of an operating section 6 of the main body 8, then, operational conditions at the time of fault occurrences are correctly analyzed. |
