Go Online with the Controller
Considerations
The programming software determines whether you can go online with a
target controller based on whether the offline project is new or whether
changes occurred in the offline project. If the project is new, you must first
download the project to the controller. If changes occurred to the project, you
are prompted to upload or download. If no changes occurred, you can go
online to monitor the execution of the project.
A number of factors affect these processes, including Project to Controller
Match feature, the safety status and faults, the existence of a safety task
signature, and the safety-lock/-unlock status of the project and the controller.
Project to Controller Matching
The Project to Controller Match feature affects the download, upload, and go
online processes of standard and safety projects.
If the Project to Controller Match feature is enabled in the offline project, the
programming software compares the serial number of the controller in the
offline project to that of the connected controller. If they do not match, you
must cancel the download/upload, connect to the correct controller, or
confirm that you are connected to the correct controller, which updates the
serial number in the project to match the target controller.
