Importing Control Expert Classic project returns error 'The IO Scanning mode must be set to enhanced'

Importing a 'Control Expert Classic' project returns the following error:



This occurred because the 'Control Expert Classic project' was not built using Control Expert 15.1 Classic with the I/O Scanning Mode set to Enhanced before creating the export file (.zef).  This is required because:

• The I/O scanning mode cannot be changed after import.
• The Topology Manager only supports Enhanced mode.

Use the following steps to set the IO Scanning mode to enhanced:

• Open the project with Control Expert Classic 15.1.
• Open the project settings.
• Click on Build Settings.
• Click on IO Scanning mode.
• Select Enhanced from the drop down menu.
• Click on Apply.
• Save the changes.
• Export the project as a '.zef'.
