用以表示工艺过程状态的显示画
面,工艺流程画面是典型的自由图形显示。
在自由图形中,当前的过程数据或过程状态可以数字或模拟形式进行显示(如棒图、动态填充或
趋势窗口) .画面显示中的图形符号可根据过程状态进行置换、闪烁、变色以及位置变化,即进行动
态显示。所选择的过程变量可通过流程画面中的面板或通过标准分组画面进行显示操作。
如果组态了画面调用热区或调用按钮,则可在自由画面中设置指定的画面调用体系,它确定彼此
之间的调用关系,便于用户监视操作。另外位于屏幕顶部稍偏下处的显示菜单提供了–个标准的画面
调用体系。随时可通过该菜单调用各种类型显示画面,在相应画面中可显示所需过程点的信息.

the Freelance 800F system can be controlled by
It consists of a number of process control stations connected to I/O units. you can choose this
Some process stations are in redundant mode (CPU redundancy, fieldbus module redundancy
redundant) or non-redundant mode. Modular pluggable input/output modules
Blocks are freely selected and used according to the type and number of system process signals.
AC800F controller connects remote I/O or field device via fieldbus
ready.
system communication
Communication between operator level and process control level using TCP/IP
Protocol system bus (based on Ethernet), you can choose different
transmission medium such as AUI, twisted pair, fiber optic or coaxial cable.
Freelance OPC server for connecting to higher-level operators
station (800xA) or other OPC client. Freelance Control System
Real-time process values and alarms in the system can be accessed via OPC.
We also provide a C language programming interface to embed external
In Windows operating system applications, it is suitable for implementing user
Communicate with non-standard OPC, ie DMS-API software package.
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)

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:
Project-wide modification of names, comments, data or module types
●Search and display based on specific criteria
● Cross reference can be used in systems that use a large number of variables or process points
Programs and drawings to quickly find the desired variable or process point within the scope
