PROBLEM TO BE SOLVED: To provide a storage program control type automatic exchange that can quickly analyze a processing process of a control program on the occurrence of a fault. SOLUTION: The storage program control type automatic exchange is provided with a main storage device 31 that stores a control program, an arithmetic processing unit 30 that conducts arithmetic processing on the basis of the control program stored in the main storage device 31, a fault retrieval storage device 32 that stores an address of processing by the arithmetic processing section 30 according to the control program in a normal state, an auxiliary storage device 33 that stores an address of the control program mapped by the main storage device 31 and a source code of the control program corresponding to the address, and a display device 23. The storage program control type automatic exchange retrieves an address stored in the auxiliary storage device 33 on the basis of the address stored in the fault retrieval storage device 32 on the occurrence of a fault to allow the display device 23 to display the source code.
