Included is debug information acquisition means 7 for storing in the area 8, acquisition debug information type instruction changing means 6 for writing the acquired debug information type instruction designated from the console 9 to the debug information management table 5, and communication system control means 2. There is. That is, in this embodiment, as shown in FIG. 1, a communication system control means 2 which is a communication control means for controlling data transmission / reception with another device, and information indicating an operation locus of the communication control means at the time of startup. In the debug information management table 5 and the acquisition debug information type instruction receiving means 3 for extracting the acquisition type designation information for designating the type of debug information which is the information to be recorded in the environment definition file 4 and storing it in the debug information management table 5. Debug information acquisition means 7 for extracting debug information from the information indicating the operation trajectory of the communication control means according to the stored acquisition type designation information and storing it in the debug information storage area 8.
Further, as a feature of the present invention, an acquisition debug information type instruction changing unit for updating the contents of the debug information management table 5 according to the change information for the debug information type input from the console 9 during operation. 6 is provided.

Next, the operation of this embodiment will be described. Figure 2
3 is a flowchart showing a processing procedure of the acquisition debug information type instruction receiving means 3. The acquisition debug information type instruction receiving unit 3 starts the receiving process in response to a command from the communication system control unit 2. In step S21, the value instructing the debug information to be acquired from the environment definition file 4 is extracted, and the value instructing the debug information to be acquired in step S22 is stored in the acquired debug information instructed value storage area in the debug information management table 5 and accepted. The process ends.

FIG. 3 is a flow chart showing the processing procedure of the debug information acquisition means 7. When the debug information is generated, the communication system control means 2 gives an instruction, and the debug information acquisition means 7 starts the acquisition processing. In step S31, the acquired debug information instruction value is referenced from the debug information management table 5, and it is determined in step S32 whether the debug information requested to be acquired is instructed to be acquired. When it is determined that the debug information is not acquired, the debug information acquisition unit 7 ends the acquisition process. If it is determined that the debug information has been acquired, the process proceeds to step S33, the debug information is stored in the debug information storage area 8, and the acquisition process ends.

FIG. 4 is a flow chart showing a processing procedure when the communication system control means 2 receives the acquired debug information type instruction value change command. When a command is input from the console 9, the communication system control means 2 starts command reception processing. It is determined whether the command received in step S41 is the acquired debug information type instruction value change command. If it is the acquired debug information type instruction value change command, the process proceeds to step S42 to notify the acquired debug information type instruction change means 6 of the received change command and the contents of the change, and the command reception process is ended. If the received command is not the acquired debug information type instruction value change command, the process proceeds to step S43,
After performing the processing corresponding to each command, the command reception processing ends.

FIG. 5 is a flowchart showing a processing procedure of the acquisition debug information type instruction changing means 6. In response to the acquisition debug information type instruction value change command acceptance notification from the communication system control means 2, the acquisition debug information type instruction change means 6 starts the change processing. In step S51, the acquired debug information type instruction value input from the console 9 is extracted. The acquired debug information type instruction value fetched in step S52 is used to change the debug information type instruction value in the acquired debug information instruction storage area in the debug information management table 5, and the dynamic change process is terminated.
