FANUC A02B-0303-C205位置检测接口单元
DPM1随后切换到清除状态。如果此参数被禁用，则DPM1即使在发生故障时也保持在操作状态，用户可以控制系统的反应。另请参阅第49页的设置选项卡。同步和冻结模式除了DPM1（DP Master Class 1）和分配的从设备之间的正常循环通信外，主设备还可以通过多播向一组从设备发送控制命令同步和冻结。使用sync命令，寻址的从设备将将输出冻结在当前状态。当输出状态保持不变时，主机接收的新输出值将被存储。在接收到下一个同步命令之前，不会将存储的输出数据发送到输出。使用“unsync”命令终止同步模式。
The DPM1
subsequently switches to the clear state. If this parameter is disabled, the DPM1
retains in the operate state even in the event of a fault and the user can control the
reaction of the system. Please refer also to Settings Tab on page 49.
Sync and Freeze Mode
In addition to the normal cyclic communication between the DPM1 (DP Master
Class 1) and the assigned slaves, a master can send the control commands sync and
freeze via multicast to a group of slaves.
With the sync-command the addressed slaves will freeze the outputs in their current
state. New output values received by the master will be stored while the output
states remain unchanged. The stored output data are not sent to the outputs until the
next sync command is received. The Sync mode is terminated with the “unsync”
command.
