Abstract
A control system includes a control device that repeatedly performs a series of pieces of processing including I/O refresh processing and program execution processing. The control system includes: a first obtainment unit that obtains a first sample value group collected by repeatedly performing the I/O refresh processing in a first control period; a second obtainment unit that obtains a second sample value group collected by repeatedly performing the I/O refresh processing in a second control period longer than the first control period; a determination unit that determines whether a first frequency component in the first sample value group and a second frequency component in the second sample value group are substantially identical to each other; and a change unit that changes the first control period to the second control period under a condition that the first frequency component and the second frequency component are substantially identical to each other.
