由于显示面板格式是系统预先定义
好的，因此只要定义过程点无需附加编程，面板显示即可使用。

面板显示是弹出式窗口，与标准显示或自由格式的用户画面同时显示在监视器上。它可以随意拖
动，不用时可关闭。所选的过程点随时可以通过面板来显示或操作。

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。
PS provides more than 220 functional modules (control algorithm subroutines), in addition to the basic ones specified in the IEC 61131 3 standard
In addition to this content, many powerful and rigorously tested function blocks from actual engineering applications have been expanded. any complex control
The scheme can be realized by the combination of these function blocks.
The function blocks provided by the system mainly include the following categories:
o
Analog processing
o
digital processing
loop regulation
Logical sequence control
c
logic operation
Monitoring function
Collection function.
c
arithmetic operations
c
TCP/IP protocol communication interface
Modbus protocol communication interface
1EC870-5 protocol communication interface (Telecontrol)
4.2 Field Controller PS
Industrial” field controller PS is a special process control station, which is embedded with field bus communication interface for users to use
Fieldbus technology offers very flexible options. Each PS allows to insert 4 fieldbus interface cards (the card type can be different),
Each card is connected to 1 field bus to collect process data and diagnostic information from the bus, the interface card is easy to replace and plug and play
(Plug & Play), and can be plugged and unplugged.
The field controller PS has the following characteristics:
o
Flexible:
