You change the hierarchy group names of the areas and units in your plant using Smart Engineering Manager. A message is displayed at the start of Smart Electrical and Smart Electrical Options Manager informing you that changes have been made to the hierarchy names and that you should run the Apply Naming Conventions command in Smart Electrical to complete these changes. Using the Apply Naming Conventions command the changes made in the hierarchy names are propagated to the item type names through the entire plant according to the definitions created in the Options Manager.
