PROBLEM TO BE SOLVED: To synchronize a plurality of devices which are synchronized with common synchronizing signals, and perform synchronization processing at a processing cycle which is longer than a cycle of the synchronizing signal.SOLUTION: One safety drive unit 3A out of a plurality of safety drive units has a master safety device 3A-3, and the other safety drive units 3B, 3C have slave safety devices. The master safety device and the slave safety devices are synchronized with synchronizing signals φ outputted by a controller 1, respectively, and cyclically perform safety control at a processing cycle of k-times (k is an integer of 2 or more) of a cycle of the synchronizing signal. The master safety device transmits a multi-cast signal MC indicating the generation timing of the synchronizing signal which is synchronized with the processing cycle of the device, and the slave safety device synchronizes the cycle of the device to the synchronization signal φ which is generated together with the multi-cast signal MC.

    【課題】 共通の同期信号に同期し、同期信号の周期よりも長い処理周期で周期処理を実行する複数の装置を同期化させる。【解決手段】 複数の安全ドライブ装置における1の安全ドライブ装置3Aはマスタ安全装置3A−3を有し、他の安全ドライブ装置3B、3Cは、スレーブ安全装置を有する。マスタ安全装置およびスレーブ安全装置の各々は、コントローラ1が出力する同期信号φに同期し、かつ、同期信号の周期のk倍(kは2以上の整数)の処理周期で周期的に安全制御を行う。マスタ安全装置は、当該装置の処理周期を同期させている同期信号の発生タイミングを示すマルチキャスト信号MCを送信する。スレーブ安全装置は、マルチキャスト信号MCとともに発生する同期信号φに当該装置の処理周期を同期させる。【選択図】図1
