Chapter 17 Auxiliary Editing Tools The programming languages such as LD and SFC are supported by the conversion of DVP series and AS series. Thus these two programming languages can be used without problem during conversion. When any unsupported programming language is used, the unsupported part will be deleted, after the conversion is done. For instance, a STEP symbol is declared in DVP series but this symbol will be deleted after the conversion, since AS series does not support this variable. If Kn is used in devices for DVP series, after the conversion, an error will occur, since AS series does not support Kn. Unsupported parts will be deleted. Before conversion Afore conversion 17-13
