Step 12: Compiling the safety program

In this step, you compile the safety program and the hardware configuration.
A consistency check is performed on the execution-relevant F-blocks when the safety
program is compiled, that is, the safety program is checked for errors. Any error messages
are output in an error window. After a successful consistency check, the additionally required
F-blocks are generated automatically and added to the F-runtime group in order to generate
an executable safety program.
Click the "Play" button to start the animation file. Click the other control elements to rewind,
pause, go back, or go forward.
Procedure
1. Select the fail-safe CPU in the project tree.
2. In the shortcut menu for the fail-safe CPU, select "Hardware and software (only
changes)".
The safety program is now compiled.
Result
If compilation is successful, the result is always a consistent and executable safety program
comprising all F-blocks with F-attributes. You are notified of this with the message "Safety
program is consistent".
