Generating Code

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

Choose to build the project or the device. Also verify the syntax of POUs or the

Global

library. Building or verifying a selected project element, only verifies or builds the code for the selected element.

Choose to clean projects and devices. Cleaning projects and devices deletes the intermediate and output files generated during the last build operation. After cleaning, regular updates cannot be performed. To retain the capacity to perform regular updates, perform subsequent builds for a project or device rather than cleaning then building it. However, intelligent updates may be performed after cleaning a project or device.
