The project tree is the central instrument for managing the entire user program and commissioning. All project configuration data is displayed as a tree structure.
Project data base
All configured signals, variables and tags are managed in the Freelance system as lists in a common project database, which is easy to archive.
Graphical configuration with powerful editors according to IEC 61131-3:
- Function block diagram (FBD)
- Instruction List (IL)
- Ladder diagram (LD)
- Sequential function chart (SFC)
- Structured text (ST)
The required hardware structure can be configured in a graphical system overview and the system communication can also be defined there. It is possible to assign particular Freelance operator stations to specific controllers.
Furthermore, detailed information can be obtained on the operator and process stations, together with their modules and the controllers with their connected fieldbus lines. In the station overview display, the operator and process stations can be equipped using selection lists. Specifications for processing, display and I/O channel assignment can be made for the individual modules of the controllers. And all this with just a few clicks.
Fieldbus and field device configuration
The respective bus parameters, for instance the baud rate, number of subscribers and time constants, can be set for each fieldbus module.
Freelance Engineering (Control Builder F) also suggests a setting for the bus parameters in line with how the fieldbus is equipped. This makes work easier for those new to the subject. In the configuration view of the fieldbus line, new PROFIBUS slaves can be integrated into the fieldbus line using a GSD-file or FDT technology. Using the template concept, it is also possible to integrate completely pre-configurable PROFIBUS slaves by means of drag and drop.
