以同样的方式，冻结命令使寻址的从设备进入冻结模式。在此模式下，输入的状态被冻结在其当前值。在主设备发送下一个冻结命令之前，不会再次更新输入数据。使用“解冻”命令终止冻结模式。CI854/CI854A不支持同步和冻结模式。监控DP-V0通信DPM1和从设备之间的循环通信由主设备和从设备本身监控。如果CI854/CI854A主设备检测到与从设备的通信故障，它将指示相应的从设备受到干扰。如果启用，自动清除模式将被激活。在CI854/CI854A上，实现了特殊处理，以支持主设备和从设备的冗余。在这两种情况下，监控定时都考虑了主设备和从设备的故障切换。
In the same way, a freeze command causes the addressed slaves to enter freeze
mode. In this mode, the states of the inputs are frozen at their current value. The
input data are not updated again until the master sends the next freeze command.
Freeze mode is terminated with the “unfreeze” command.
The CI854/CI854A does not support sync and freeze mode.Monitoring the DP-V0 Communication
The cyclic communication between the DPM1 and the slaves is monitored by the
master and the slaves itself.
If the CI854/CI854A master unit detects a failure in the communication with a
slave, it will indicate the corresponding slave as disturbed. If enabled, Auto Clear
Modus will be activated. On CI854/CI854A a special handling is implemented to
support also redundancy for master and slave. In both cases the monitoring timings
consider the failovers of master and slave.
