Summary:PROBLEM TO BE SOLVED: To provide a new configuration for executing, in functional units, processing in response to interruption of power to be supplied to an arithmetic unit.SOLUTION: An arithmetic unit constituting a control device comprises: a communication circuit for exchanging data with one or more functional units through a communication line; a processor for executing a user program for carrying out at least one of arithmetic processing that uses the data acquired from the one or more functional units and processing that creates data to be transmitted to the one or more functional units; and a monitoring circuit that is connected to the communication circuit and processor. The monitoring circuit performs notification for executing processing in response to interruption of power supplied to the arithmetic unit from the communication circuit to the one or more functional units on the basis of at least one of detection of the interruption of power to be supplied to the arithmetic unit and reception of advance notice before interrupting power to be supplied to the arithmetic unit.SELECTED DRAWING: Figure 3 【課題】演算装置へ供給される電力が遮断されたときに、機能ユニットにおいて、それに応じた処理を実行させるための新規な構成を提供する。【解決手段】制御装置を構成する演算装置は、通信線を介して1または複数の機能ユニットとデータを遣り取りするための通信回路と、1または複数の機能ユニットから取得されるデータを利用した演算処理、および、1または複数の機能ユニットへ送信するデータの生成処理、のうち少なくとも一方を実施するユーザプログラムを実行するためのプロセッサと、通信回路およびプロセッサに接続された監視回路とを含む。監視回路は、演算装置に供給される電力の遮断の検知、および、演算装置に供給される電力を遮断する前の予告通知の受信、の少なくとも一方に基づいて、通信回路から1または複数の機能ユニットに対して、演算装置への電力供給の遮断に応じた処理を実行させるための通知を行う。【選択図】図3
