处于工作状态时是不可以关闭的。例如，这可能是由于复杂的自动化过程或者重启动成本较高而造成的。因此，可能仍需要移除重组态。
通过CiR 进行的热更改可让您在RUN 模式下对组态执行某些修改。此操作将在短时间内中断处理。此时间段上限的预设缺省值为1s，如有必要，可改变此值。在中断期间，硬件输出将保持其最后的值。

Fieldbus interface replacement card fi830f/fi820f/fi810f
Fieldbus interface cards are divided into several types according to different protocol standards. Each interface card provides – a fieldbus interface (PROFIBUS,
Can, FF, MODBUS, etc.). The configuration and parameter settings of the interface card itself and the field instrument (or remote i1/0) on the connected fieldbus are still
It is designed by the industrial “unified tool control bui lder without additional software. The interface card can be configured redundantly (separated between each other
Redundant basic unit pm802f) and can be plugged in and out and replaced online.
Fi830f: PROFIBUS DP interface card, as the master station, can connect 126 PROFIBUS DP slave stations, and the communication rate can reach 12mbd
One PS can plug in 4 fieldbus interfaces, connect 496 fieldbus devices, and one city (subsystem) of industrial “system can
Connect 4960 fieldbus devices (10000 i/0).
Fi820f: two serial interfaces are provided to connect the serial protocol equipment. The maximum transmission rate is 38.4kbd and can be configured. Its Standards Association
