The
Block Library
 provides a graphical view of all operators, functions, and function blocks available for the program organization units (POUs) of a project. When developing POUs:
  • Drag and drop blocks from the library to the language container
  • Sort blocks that display in the library according to alphabetical order, categories, scope, or limit a search based on names. Blocks display in either tile or list views.
