FIG. 3 shows a configuration example of the hardware configuration information table of the central processing unit according to the embodiment of the present invention. The hardware configuration information table 15 in the central processing unit 1 is composed of information on the device type, device number, device attribute, and access path number. The device search unit 12 in the central processing unit 1 issues the device information reference commands a to c to the input / output control devices 2 to 4 using the access path number generation unit 121 that sequentially generates the access path numbers and the access path number as a parameter. The device information reference unit 122 is configured to operate.

(Step 41) Control program 11 of central processing unit 1
When is started, the initial setting unit 111 in the control program 11 first runs, and the device searching unit 12 is called by the initial setting unit 111. The access path number generation unit 121 of the device search unit 12 generates an access path number. (Step 42) Device information reference commands ac using the access path number generated in step 41 as a parameter
Are issued to the input / output control devices 2 to 4, respectively. (Step 43) Device information analysis unit 13 of the central processing unit 1
Determines the presence / absence of a connected device based on the presence / absence of a command response to the commands a to c. If there is no response, it is determined that there is no device to be connected, the process returns to the first process, the next access path number is generated, and the same process is performed. (Step 44) When the command is normally executed and the device information d to f can be acquired from the input / output devices 2 to 4, the central processing unit 1 judges the device type and income information from the device type name in the information. The hardware configuration information editing unit 14 is called with the device number, the device attribute, and the access path number when the device reference command is extracted extracted from the parameters. (Step 45) The hardware configuration information editing unit 14 of the central processing unit 1 edits the parameters to the format referred to by the control program based on the delivered parameters, and registers them in the hardware configuration information table 15. (Step 46) The processing of the above steps is performed for all access path numbers, and if the reference of all access path numbers is not completed, the procedure returns to step 41, while the reference of all access path numbers is completed. If so, the creation of the hardware configuration information table ends.

After the above processing is completed, the control is returned to the control program. The control program refers to the hardware configuration information table created above for the subsequent processing.
