Abstract
PURPOSE:To obtain the abnormality information without deciding mutually the factor of the abnormality at a site by securing such a constitution where a communication control means performs the switch to a self-diagnosis program to give the diagnosis to a main CPU and transmits the result of this diagnosis even in case of generating abnormality in on-line program of the main CPU. CONSTITUTION:When a trouble diagnosis command is received from a station of the remote side via a transmission circuit 11, a communication control means 12 switches a program switch control means 14 to a diagnosis program memory 18 from an on-line program memory 17. Then a main CPU 13 executes the program 18 and the result of diagnosis is sent to the station of the remote side via the means 12. Thus the abnormal state of the CPU 13 is recognized at the center side. As a result, the abnormality factor of the CPU 13 is decided before a manual operation carried out at a site and an accurate countermeasure is secured to the abnormality.
