Hi Jibu,
Make sure that you have a valid Simulink enumeration type on your MATLAB path.
Then, in System Composer's interface editor, create an interface with at least one interface element. Open the property inspector then click on that element. You should be able to type something into the Type field. Type "Enum: myEnumName" and then when you assign that interface to ports, you can use Simulink to pass an enumeration through that interface.
lrc.m (example enum)
classdef lrc < Simulink.IntEnumType
% lrc Enumeration type definition for use with System Composer profile
enumeration
left(0)
right(1)
center(2)
end
end
