NOTICE!
All configured safety input and output variables can also be seen in
non-safety CODESYS project (e.g., for their visualization in operator
panels, data logging, etc.).
The difference comparing to CODESYS Safety project is that end-user
is not able to modify the values of those safety variables from non-
safety CODESYS project. It is prohibited by proper design.
