Emerson Exchange 365

Chris,
The customization capability of DeltaV Operate includes loading the display list. In DeltaV Operate configure mode, look in the Standard directory for a picture named:
UserSettings.grfor
<workstation-name>_Settings.grf, with <workstation-name> replaced by the name of the workstation.
On the right-click menu of the picture, selecst Edit Script, and search for "History List Picture". The comments explain how to set up the preload of the display list, so you can figure out how to remove the displays that are no longer in use. You could either comment out the lines with the old pictures or replace the picture names with current pictures.
Good luck!J.D.
