Upgrade MES ​.NET controls for AVEVA OMI applications

If your System Platform IDE includes an OMI App that contains MES .NET controls, that OMI App must be deleted and recreated using the current version of the MES .NET controls.

If you import a newer version of the .NET controls that excludes controls that are no longer used (for example, the Entity Usage Editor, or the Labor Usage Editor), the deprecated controls will not be available for use in the OMI pane.

1. Perform the MES version upgrade, which should include the .NET controls.

2. In the System Platform IDE Graphic Toolbox, locate the OMI App object that contains MES .NET controls and delete it.

3. In Windows File Explorer, navigate to the MES application folder.

4. Locate the MES .NET controls folder that was the source folder used during the .NET controls import for the OMI App.

   Typically, this folder was created by making a copy of the MES\Controls folder and naming it with the name of the OMI App for which it was created (for example, MESControlsForOMI).

5. Delete this .NET controls folder.

6. In the System Platform IDE, perform the Import OMI App operation and select the new OMI App folder with the updated MES .NET controls—MES\MES OMI Controls— to recreate the OMI App object with those controls.

7. Open any OMI pane that previously contained MES controls that have been removed (for example, Entity Usage Editor or Labor Usage Editor) and remove the reference to the no longer available OMI app.
