• Keep a startup list if components have to be replaced
• Differentiation between online/offline dictionary, existence of current XML description
• use "CoE reload" for resetting changes
Introduction
The CoE overview contains objects for different intended applications:
• Objects required for parameterization during commissioning
• Objects for indicating internal settings (may be fixed)
The parameterization and the objects required for normal operation will be presented first of all below. All
further objects that are not needed for the normal application case can be found in the lower section of the
