Control Apparatus

A control apparatus controlling operations of one or more control object apparatuses, comprising

• a plurality of computing resources that include multiple types of computing resources related to control of the operations of the one or more control object apparatuses,
• wherein the plurality of computing resources include an interface unit, a storage unit, and a processor unit,
• the interface unit includes one or more I/O ports coupled to the one or more control object apparatuses, and one or more network ports coupled to a network,
• the storage unit includes one or more memories,
• the processor unit includes one or more processors,
• a program group downloads at least one of one or more object programs that are one or more programs among one or more control programs and one or more information programs, from a program distribution apparatus, via the network and the one or more network ports, and
• changes execution management data that indicates an upper limit of resources that are resources usable by the object programs in relation to the plurality of computing resources, at timing different from timing of the download,
• the program group is one or more programs other than the one or more control programs and the one or more information programs,
• each of the one or more control programs is a program that performs a scan operation of outputting control information on the control object apparatus coupled to the I/O port, and
• each of the one or more information programs is a program that performs information processing different from the scan operation.
