Requirement: Offline mode and your application is compiled without errors. The connection to the PLC is configured and the PLC is running. The application is active. The following steps demonstrate the options:

  1. Click “Online  Login”.

    The ‎<application name>.app‎ boot application file is created on the PLC with the CRC of the ‎<application name>.crc‎ boot application.

  2. Explicitly click “Online  Create Boot Application”.

    The files on the PLC are replaced by new files.

  3. Log out.

  4. Change the application. Log back in to the controller.

    You are prompted to perform an online change. You see the “Update boot application” option in the same dialog. It is disabled by default. The default setting can be changed in the “Properties” of the application object in the “Boot application” category.

  5. Keep the option cleared and continue login.

    A new boot application file is not created.

  6. Logout again. Close the project. Stop the PLC. Restart the controller.

    The boot application that was created above is running on the PLC.

You can save the encrypted boot application on the PLC. These settings for the application object are defined in the “Properties” in the “Application Build Options” category.
