PURPOSE:To prevent the confusion occurring at a remote maintenance center at operation of the maintenance and to realize the effective maintenance diagnosis and at the same time to automatically inform fault information by providing a diagnostic bus control part and a microprogram execution control part, etc. CONSTITUTION:When an abnormality detecting means 22 set in a microprogram execution control part 20 detects the abnormality during the operation of a data processor, a control means 21 activates a fault information collecting means 23 to collect the fault information via a diagnostic bus 2 and a diagnostic bus control part 10. Then the means 21 discriminates the state of an operation mode switch 51 of a maintenance panel 50 via an operation mode deciding means 25. The means 21 activates a transfer means 24 in a normal operation mode to automatically report the fault information to a remote maintenance center. Then the means 21 inhibits the start of the means 24. Thus it is possible to prevent the confusion occurring at the remote maintenance center and to attain the effective maintenance diagnosis at operation of the maintenance. At the same time, the fault information is automatically informed. |
