The control device: downloads at least one of one or more designated programs (one or more programs of one or more control programs and one or more information programs) from a program distribution device via a network and one or more network ports; and, at a time that is different from the time when the download was performed, changes the execution management data showing, in relation to a plurality of calculation resources of the control device, the resource upper limit of resources that are usable by the designated program. Each control program is a program that performs a scan operation for outputting control information of a device subject to control connected to an I/O port. Each information program is a program that performs information processing that is different from the scan operation.
