Generating Code

Before downloading code onto a target systems, build the code for the whole project. This operation verifies and builds the code for all libraries, controllers, programs, functions, and function blocks including builds information used to recognize systems on networks. Once a project is built, subsequent build operations only recompile the parts of the project that need regeneration.

Choose to build the project, controllers, or libraries. Also verify the syntax of program organization units (POUs). Building or verifying a selected project element, only verifies or builds the code for the selected element.

Choose to clean projects and controllers. Cleaning projects and controllers deletes the intermediate and output files generated during the last build operation. However, after cleaning, updates cannot be performed. To retain the capacity to perform updates, perform subsequent builds for a project or controller instead of cleaning and then building it.
