A technique for managing module-related information in a modular system includes a plurality of modules having different functions and a base module for controlling the operation of each of the plurality of modules by interfacing with each of the plurality of modules. The technique includes obtaining module-related information stored in a module connected to the base module, and storing the module-related information obtained from the module in a module information memory accessed by the base module. Accordingly, the method for managing module-related information can be used to transmit information necessary for operation of each module to a base module or can produce as methods for updating module-related information and maintaining the latest version of module-related information.
