As an option, the debugger may display real time status of FBD flow lines during debug of simulation.
This option must be selected before compiling the project. It is selected from the "Enhanced" tab of the "Compiling Options" dialog box.
When this option is selected, the compiler automatically add variables and instructions to the generated application code so that status of all FBD flow lines can be spied during debug of simulation.
Selecting this option increase the size of the downloaded code and may lead to less runtime performance. It is recommended to uncheck this option when the application is fully tested and compiled in RELEASE mode for its final implementation.
