顺序功能图垦示
Industrial”是最早实现SFC(顺序功能图)显示的系统，SFC是基于IEC61131 3标准的SFC，从
一个标准SFC显示中可以显示PS中相应的顺序功能图(SFO程序的当前状态。
在SFC显示中，当前正被执行的程序步和已处理过的程序路径用不同的颜色显示。通过一个显示
程序步和步进条件情况的判别窗的颜色变化，可以很容易地检测故障状态(如未满足过程判别条件或
运行超时)。可以对判别窗中所显示的变量进行操作。
组态时可以为每- -程序步或步进条件指定相应的调用画面。操作员可以访问SFC显示的每一程序
步或步进条件以便立即选择所需信息。
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
