A control device includes a main storage device that stores a user program and program packages in a nonvolatile manner; a main memory having a package management module arranged therein; and a processor. The package management module performs a deployment process for selecting, from the program packages, a package to be deployed based on a version of the user program, and arranging, from the package to be deployed, a version of a program compatible with the version of the user program in the main memory.
