Synchronization between the runtime application and the controller

When downloading the HMI project to the HMI device, the synchronization service connects the runtime application to the controller referenced in the HMI project. After the synchronization service connects to the controller, it reads data from the controller to determine if it matches the data in the HMI project. If the data does not match, the data in the HMI project automatically synchronizes with the data in the controller.

When the runtime application runs on the HMI device, the synchronization service checks if the

Logix Designer

file in the controller was updated. The

Logix Designer

project file in the controller can be updated using the online editing features in

Logix Designer

. If the project file was updated, the synchronization service will automatically synchronize data between the

Logix Designer

project file referenced in the runtime application and the newly updated

Logix Designer

project file in the controller.

Configure system tags to display information about the synchronization status of the runtime application and the Logix5000 controller or use the ControllersGeneral screen in the

Predefined Screens

folder.
