In the investment of modern automation system, due to the hardware equipment department
It only takes up less cost in the whole system, then write engineering applications
The cost of software becomes increasingly important. Generally speaking, a self
The engineering application software cost of the automation project accounts for about the entire project.
About 50%, it is not difficult to see that the migration of cost structure creates a lot of innovation for users.
Create an opportunity to optimize project investment, therefore, it is necessary to start from engineering programming
Think about lowering costs in the first place!
This is what we developed the Freelance 800F system for:
Keeping hardware prices consistent with those of programmable logic controllers
In this way, cost efficiency can be improved by reducing user engineering costs.
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.

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 intelligent field devices, including
Including the integrity ａnd consistency check of the user program.
The programming language strictly complies with the international standard of IEC61131-3, ａnd has
There are high-performance graphics editing functions:
