MULTIPLEXING DEVICE, AND FAILURE OCCURRENCE ORDER DISPLAY METHOD, AND FAILURE OCCURRENCE ORDER DISPLAY CONTROL PROGRAM

摘要

PPROBLEM TO BE SOLVED: To provide a multiplexing device for identifying a failure part in real time even when multiple failure occurs. PSOLUTION: The multiplexing device includes: two or more electronic apparatuses 1, 2 each including an apparatus control part; monitoring electronic apparatuses 3, 4 each including a monitoring part monitoring an operation state of each electronic apparatus and analyzing failure occurrence order; display parts (FAULT-A, FAULT-B) for each of the apparatuses; a bus part 12 including a control bus and a bus for monitoring; and light transmission parts each transmitting failure information indicating the failure occurrence order toward the display parts for the apparatuses from the monitoring electronic apparatuses 3, 4. The monitoring electronic apparatuses include failure indicator lights 8, 9 inputting display optical signals to each of the light transmission parts, and lighting control function parts controlling each of the failure indicator lights according to the failure occurrence order.
