过程变量的当前值可同时反映在数值窗口
与趋势窗口中，为功能测试与调整提供了极其方便的手段。不仅可显示当前调出程序的1/0变量，而
且能够显示来自其它程序变量和中间变量的实时值。
可以在调试过程中修改参数以实现程序优化设置，调试者可决定修改是临时的或永久性的。

How the Freelance 800F process control system helps users reduce
Low engineering cost?
●By using a complete engineering tool (Control Builder
F) to configure the entire control system, including automation functions
function, operator interface display and logging, and configuration of the fieldbus.
equipment (PROFIBUS, FOUNDATION Fieldbus,
HART, etc.) and device parameter settings.
● Automatic generation of global data between the process control station and the operator station
According to communication.
For field devices, process control stations and operator stations, a unified global database is used for the entire control system, thereby reducing
cost and time investment in establishing data communication and interactive access.
And ensure the consistency of data throughout the system.
●Provide system-wide unified inspection of user applications, overriding
from process control stations, operator stations to
