FB_ProtectedVariables Function Block

(*
    Contains different types of "protected" variables that you could not normally write to in
    production PLC code, but would need to overwrite for testing purposes. Used for testing the
    WRITE_PROTECTED_* functions, but this FB doesn't contain any tests itself.
