Function Block Diagram - FBD
A code body programmed in the graphical language FBD is composed of functions and function blocks which are connected with each other or with variables using lines. These lines can also be connected with each other. In FBD networks it is not possible to connect outputs with outputs.
The set of connected objects is called FBD network.
Connectors can be used in case of large networks for better structuring the elements in the worksheet. Connectors replace connection lines.
Jumps can be used to jump to a label in the current worksheet.
