Refactoring dl-permalink__symbolPermalink

In general, refactoring is a technique for improving the design of existing software code without changing the way it functions.

In CODESYS, refactoring provides functions for renaming objects and variables and updating referenced pins. You can display all occurrences of renamed objects and variables and then rename them all at once or individually. In “Tools  Options”, you can also configure where CODESYS will prompt you for refactoring.

  • Renaming global variables
  • Adding and removing input variables
  • Reordering variables in the declaration
  • Changing a variable declaration and applying refactoring automatically
