You must set the attribute in the Generate event action, using in1.

function [entity,events] = generate(obj,storage,entity,tag,in1)
    entity.data.Attribute1 = in1;
    events = [];
end

Thanks for you answer!

When I do that I get an error that the attribute datatype is set incorrectly, where and how do I specify the entities attributes?
