The FBDK supports network segment types, as defined in the 2 ^nd Edition of IEC 61499-1.

You can define new segment types with the following procedure:

1. Start the FBEditor.
2. Create a new segment type in the editor by opening:
   • a file containing an existing segment type, for instance the Ethernet file in the net folder, as shown above; or
   • the SegmentType file in the template folder.
3. Edit the segment type's elements:
   • Edit the segment type's properties.
   • Edit the segment type's interface (data inputs, i.e., parameters, only).
4. When your editing is complete, save your work with the Save As... button.
   • It is a good idea to save your work from time to time while editing, too!
5. Document your work. It's not done until it's documented!
