The decorated variables are hidden and therefore cannot be exported.

However, if the source code file from the compiled library is available, or if CODESYS has been started with the command-line option conditionalshowsymbols, then the decorated variables are visible despite the pragma.

{attribute 'const_non_replaced'}

Replaced constants are not available in the symbol configuration editor and therefore cannot be exported.

A constant being replaced depends on whether or not the Replace constants compiler option has been selected for all constants and whether or not pragmas overwrite the compiler option for individual constants.

The variable is displayed in the symbol list only when the View, Symbols Exported via Attribute option is selected in the symbol configuration editor. The access rights, which have been defined with the pragma, are displayed In the Attribute column.
