The Workbench Studio includes a powerful feature that enables you to convert a program written in an IEC language to another language. Use the contextual popup menu in the Workspace to convert a program to another language.

  • Any conversion in between ST, IL, LD and FBD are possible. Conversion of SFC programs is not allowed. Converted POUs can be main programs, UDFBs or sub-programs.
  • The program must be saved and the project built without errors before converting a program.
  • When a program is converted to another language, its former implementation in the original language is kept until you make a change in the converted program. Thus, if you re-convert it back to the original language, you get 100% of the original contents.

info Information

When a program is converted, some presentation items (such as blank lines in ST or specific alignment in FBD) are lost.

It is possible that converting a language requires some new intermediate variables to be declared. Such variables are declared locally to the program and are prefixed with "_T".
