Replacing AUTOSWT and other PC Worx functionality

PCWorx_AUTO_SWT_FB.pngHello experts!
Another question about converting an existing PC Worx program (or in this case, a library). The picture above shows the function block „AUTO_SWT“ and the library also uses some more types like WR_CONF and RD_CONF. At this moment my PLCNext compiler does not recognize these instructions.

What is the proper way to fix this? Should a library be added to the PLCNext project, or must the code be rewritten to match the new functions?
