在从站侧，通过看门狗控制与主站的通信。如果在看门狗控制间隔内没有与主设备进行数据通信，则从设备自动将其输出切换到故障安全状态。另请参阅第70页“多主机系统”中的“连接错误”。在多主机系统中，多个主机连接到一条总线。它们要么表示独立的子系统，包括一个DPM1（DP主级1）及其分配的从系统，要么表示附加的配置和诊断设备。CI854/CI854A主机支持多主机系统。带有集成PROFIBUS主计算的Control Builder M不支持多主配置。该计算仅包括一个CI854/CI854A及其分配的从属设备。
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.
