系统分为两级:操作管理级和过程控制级。在操作管理级上不仅实现传统的控制系统监控操作功
能(操作和显示，打印，趋势显示和报警)，而且还完成系统硬件诊测及不同系统间数据交换等功
能。过程控制级实现包括复杂控制在内的各种回路调节(各种PID、比值、Simith 等)和高速逻辑控
制、顺序控制以及批量间歇控制功能

Set. The operating station 0s, engineer station es and data gateway GS of the industrial “system have adopted this platform, thus ensuring the
It is universal, open and easy to use, and brings great convenience for future technology upgrading and maintenance.
System engineering configuration is very convenient. The configuration language is based on ie0611313 industrial standard and provides function block diagram (FBD) and ladder diagram
(LD), instruction list (IL), sequential function diagram (SFC), structured text (st) and other graphical configuration modes.
