A configuration of control device capable of linking control applications even in a control system that combines a control device with another control device is provided. A first control device includes: a first program execution part outputting a first control command at every first cycle; a parsing part parsing at least a part of a first application program at every second cycle to sequentially generate an internal command; a command calculation part outputting a second control command at every first cycle according to the internal command generated by the parsing part; and an arbitration part managing a parsing process performed by the parsing part. The arbitration part adjusts an output timing of the second control command according to the internal command generated by the parsing part in response to notification of a timing from the second control device.

Control system for controlling control object and control device for linking control applications in control system

A selectable operation amount is set as a threshold value according to an input operation amount, where if a determination value obtained by adding the input operation amount and an integrated operation amount or an output error accumulated value is greater than or equal to the threshold value, the threshold value is selected as the output operation amount, and if the determination value is not greater than or equal to the threshold value, a selectable output operation amount close to the threshold value is selected, and the ON/OFF control is performed with the selected output operation amount, while the selected output operation amount is subtracted from the determination value to correct the integrated operation amount, so that the input operation can be substantially output even if it takes an operation amount other than the selectable operation amount values.
