MULTI-CORE CONTROL DEVICE

To provide a multi-core control device that performs diagnostic processing without writing and collapsing data used for a control operation when diagnosing a data area accessed by a control core.SOLUTION: A multi-core control device 1 includes a control core 11 performing processing for plant control at a fixed cycle and a diagnostic core 12 performing diagnosis and has two planes of data areas used for a control operation. Control operation processing and diagnostic processing are executed in parallel while taking exclusivity with the control core and the diagnostic core by switching the data area for the control operation processing and an area to be diagnosed with a selector 4.SELECTED DRAWING: Figure 1 【課題】制御用コアがアクセスするデータ領域の診断を行う際、制御演算に使用しているデータを書き潰す事なしに診断処理を行うマルチコア制御装置を提供する。【解決手段】マルチコア制御装置１は、一定周期でプラント制御のための処理を行う制御用コア１１と診断を実行する診断用コア１２を備え、制御演算で使用するデータ領域を２面持ち、制御演算処理のデータ領域と診断対象となる領域をセレクター４で切り替えることによって、制御用コアと診断用コアで排他を取りながら制御演算処理と診断処理が並列実行する。【選択図】図１
