As described in detail above, according to the present invention, a mounting board can be automatically identified by communication between a control board constituting a control device and another control board. Based on the result, control configuration data can be completely automatically generated by responding to a command request from a maintenance tool or the like. As a result, human errors are eliminated and efficient work is realized. In addition, it is possible to omit the collation work between each substrate and a large number of drawings, which is conventionally performed, and it is also possible to eliminate human errors that occur during the collation.

Further, regarding the control configuration data, conventionally, it was necessary to back up using the auxiliary power supply board. However, such backup is no longer necessary, and the control configuration data is not affected by a failure due to an unexpected power down. There are also effects such as easy maintenance and management of the control configuration data.
