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。
过程控制站内部通讯(控制器与I/0 等各种智能设备或现场仪表间)采用的是国际标准现场总
线。现场控制器支持Profibus等各种现场总线，Profibus 是目前世界上应用最广泛的开放型现场总
线国际标准，分为FMS、DP 及PA三级，DP 通讯速率可高达12Mb。而CAN (DIN/IS011898 标准)总线
最大特点是它的超级坚固性和数据安全性。系统当然也支持Modbus。与智能现场仪表间的通讯则通过
IART协议或现场总线(31. 25Kb的ProfibusPA和FF总线)。
操作管理级和过程控制级之间的系统通讯由Di giNetS网络(工业以太网/IEE802.3标准)实现，
用户可根据应用的实际情况选择通讯传输介质(普通电缆或光纤)和网络拓朴结构。

Project database
All configured signals, variables and process points are in Freelance
800F system’s public database for management.
● List of all variables (input, output, internal variables)
● Process point list (function block)
●Graphics
●Program
Because the database is system-wide. The data only needs to enter a
times, to avoid possible errors caused by multiple configurations.
Project database files can be easily archived or backed up.
When programmed by the user, a list of variables and labels is automatically created.
Moreover, both variables and process points can be opened and closed directly in FBD or IL
Revise.
List other features include:
