Can anyone tell me whether it's possible to display the output of a general logic object on the noticeboard?

For instance, I have a logic object created (0/1 output) depending on whether the hot water is turned on and whether the cylinder stat is calling for heat or not. If the output is called 'HW on and calling for heat', I expected to be able to add an event scheduler to display a message based around <HW on and calling for heat.Output=?> but that is just displaying that text on the noticeboard.

Thanks
