  5. FBD Editor Functions in FBD

  6. FBD Editor FBD Pane • Graphic symbols of function and function block (boxes) • Instance names of the function blocks • Comments attached to the function blocks and functions • Assignment of parameters in form of connection lines between the graphic symbols • Comment of the page and footer

  7. FBD Editor Toolbar Buttons

  8. FBD Editor Insert a Function / Function Block • Use the toolbar button • Choose “Insert > Function/ Function block” from the POU menu • Right click in thecode pane and choose “Insert Function / Function block”

  9. FBD Editor EN Input Parameter • The EN property for functions and function blocks in FBD makes it possible to write code that corresponds to “IF statements” in the Structured Text language. • When the EN input is true, the function or function block will be executed, otherwise not. • When the EN input becomes false, all outputs will keep their values from the previous cycle of execution.

  10. FBD Editor Making Connections An output parameter can be assigned to any number of input parameters but never to another output parameter. Each Parameter Separately All Parameters

  12. FBD Editor Structure Pane • Item shows the type name of the function block or function with their properties in parentheses • Comment shows the comment attached to the function block or function • Page Comment shows the comment on the top of the corresponding Function Block Diagram page • Page No is given at the first function block or function of every page of the Function Block Diagram • Instance shows the name of function blocks
