在從站側，通過看門狗控制與主站的通信。如果在看門狗控制間隔內沒有與主設備進行數(shù)據(jù)通信，則從設備自動將其輸出切換到故障安全狀態(tài)。另請參閱第70頁“多主機系統(tǒng)”中的“連接錯誤”。在多主機系統(tǒng)中，多個主機連接到一條總線。它們要么表示獨立的子系統(tǒng)，包括一個DPM1（DP主級1）及其分配的從系統(tǒng)，要么表示附加的配置和診斷設備。CI854/CI854A主機支持多主機系統(tǒng)。帶有集成PROFIBUS主計算的Control Builder M不支持多主配置。該計算僅包括一個CI854/CI854A及其分配的從屬設備。
On slave side the communication with the master is controlled via the watchdog. If
no data communication with the master occurs within the watchdog control interval,
the slave automatically switches its outputs to the fail-safe state.

Multi Master Systems
In a multi master system several masters are connected to one bus. They represent
either independent subsystems, comprising one DPM1 (DP Master Class 1) and its
assigned slaves, or additional configuration and diagnosis devices. The
CI854/CI854A master unit supports multi master systems.
The Control Builder M with the integrated PROFIBUS master calculation does not
support multi master configurations. The calculation only covers one
CI854/CI854A with its assigned slaves.
