Abstract

PURPOSE:To facilitate analysis of data without providing a circuit monitoring circuit by providing a log area for data received from a circuit in a memory, by dumping the contents of the log area when a fault occurs, and by finding the cause of a trouble on the basis of the dumped contents. CONSTITUTION:Data received from communication circuit 1 is converted from series to parallel by circuit control circuit 2 and on one-character reception, circuit 2 outputs interruption signal 7 to CPU8. On detecting this signal 7, CPU8 fetches the data and stores it in locking buffer 4 by way of data buffer 3 according to control program 5, and then data that CPU8 requires is stored in buffer 3. In the occurrence of the trouble, the contents of locking buffer 4 are dumped and on the basis of the dumped contents, the cause of the trouble is found, so that an analysis of data is easily made without using a complex device such as a circuit monitor.
