Hi,

There could be multiple methods for this, but I think it is good to use a "Simulink.data.DataConnection" object.

Refer to the example below:

% create the DataConnection object
conn = Simulink.data.connect('ddName.sldd');

% To rename, use the rename API
conn.rename('E','E1');

% If you want to change the value (or rename the enumerals)
% First get the value of the current Enum, then edit it and the set it

% Get the value
enumVal = conn.get('E1');

% Append/Remove enumerals
enumVal.removeEnumeral(1);
enumVal.appendEnumeral('Choice0',0);

% Set the Value
conn.set('E1',enumVal);

% save the changes
conn.saveChanges;

Refer to the following documentation for more details on DataConnection objects: https://www.mathworks.com/help/simulink/slref/simulink.data.dataconnection.html

The following documentation will help you to get more details on the SLDD Enumerations: https://www.mathworks.com/help/simulink/slref/simulink.data.dictionary.enumtypedefinition.html

Hope this helps!
