Abstract
(EN)
A control system controller (10) comprises a communication processing unit (30), and a control processing unit (20), and the communication processing unit (30) has a first transmission data memory (301), an abnormality detection processing unit (304), a second transmission data memory (302), and a transmission data generation processing unit (306). When the abnormality detection processing unit (304) detects an abnormality in the updating of the transmission data in the first transmission data memory (301) from the control processing unit, the transmission data generation processing unit (306) generates transmission data at the time of abnormality detection on the basis of data stored in the second transmission data memory (302), and the communication processing unit (30) transmits the generated transmission data at the time of abnormality detection to a connected device. The transmission data at the time of abnormality detection is set so as to gradually reduce the rotation speed of a servomotor in a driving device.

L'invention porte sur un contrôleur de système de commande (10) qui comprend une unité de traitement de communication (30) et une unité de traitement de commande (20), et l'unité de traitement de communication (30) comprend une première mémoire de données de transmission (301), une unité de traitement de détection d'anomalie (304), une seconde mémoire de données de transmission (302) et une unité de traitement de génération de données de transmission (306). Lorsque l'unité de traitement de détection d'anomalie (304) détecte une anomalie dans la mise à jour des données de transmission dans la première mémoire de données de transmission (301) par l'unité de traitement de commande, l'unité de traitement de génération de données de transmission (306) génère des données de transmission au moment de la détection d'anomalie sur la base de données stockées dans la seconde mémoire de données de transmission (302), et l'unité de traitement de communication (30) transmet les données de transmission générées au moment de la détection d'anomalie à un dispositif connecté. Les données de transmission au moment de la détection d'anomalie sont établies de façon à réduire progressivement la vitesse de rotation d'un servo-moteur dans un dispositif d'entraînement.

 制御システムコントローラ(10)は、通信処理部(30)と、制御処理部(20)とを備えており、通信処理部(30)は、第一の送信データメモリ(301)と、異常検出処理部(304)と、第二の送信データメモリ(302)と、送信データ生成処理部(306)とを有している。異常検出処理部(304)が、第一の送信データメモリ(301)の制御処理部からの送信データの更新の異常を検出したときに、送信データ生成処理部(306)は、第二の送信データメモリ(302)に記憶されているデータに基づき、異常検出時の送信データを生成し、通信処理部(30)により、接続されているデバイスに異常検出時の送信データを送信する。異常検出時の送信データは、駆動用デバイスのサーボモータの回転速度を徐々に減少させていくようにする。
