ABSTRACT:
Data communication equipment which includes a plurality of CPUs and transfers data between these CPUs, and which simplifies the circuit construction necessary for the data transfer. A monitor device transfers a request data containing a CPU number (corresponding to CPUN 1) storing a desired trouble data and an address (corresponding to ADR 1) storing the trouble data, to a second CPU. The requested data is sequentially transferred to the first CPU and the third CPU, and the CPU designated by CPUN 1 transfers the trouble data (DATAO 1, DATAO 3) and the address (ADRO 1, ADRO 3) storing the trouble data, to the monitor device. For this reason, each CPU need not be connected individually to the monitor device 43.
