Doing so the POU will be ignored when compiling the project, even if the POU is used in the project.For example: if a program as been already assigned to a task, you can avoid to compile it by selecting “exclude from build” instead of removing the program from the task; this will allow you to change the project behaviour without changing the project tree.Be careful, excluding from build a POU that is required by another element will generate an error message. For example: if you exclude from build a function which is called by a program, when compiling the program you’ll obtain en error message.
