• Upload to update the offline project.
• Download to update the controller project.
• Choose File to select another offline project.
• To preserve the safety task signature when the firmware minor revision is incompatible, update the firmware
revision in the controller to exactly match the offline project. Then go online to the controller.

project. The safety-lock status and safety task signature of the offline project
are overwritten by the controller. If you do not want the changes to the offline
project to be permanent, do not save the project file following the go online
process.
