在從站側(cè)，通過看門狗控制與主站的通信。如果在看門狗控制間隔內(nèi)沒有與主設(shè)備進(jìn)行數(shù)據(jù)通信，則從設(shè)備自動(dòng)將其輸出切換到故障安全狀態(tài)。另請(qǐng)參閱第70頁(yè)“多主機(jī)系統(tǒng)”中的“連接錯(cuò)誤”。在多主機(jī)系統(tǒng)中，多個(gè)主機(jī)連接到一條總線。它們要么表示獨(dú)立的子系統(tǒng)，包括一個(gè)DPM1（DP主級(jí)1）及其分配的從系統(tǒng)，要么表示附加的配置和診斷設(shè)備。CI854/CI854A主機(jī)支持多主機(jī)系統(tǒng)。帶有集成PROFIBUS主計(jì)算的Control Builder M不支持多主配置。該計(jì)算僅包括一個(gè)CI854/CI854A及其分配的從屬設(shè)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.
