I have a wincc project v7. 5 single station which communicate with 5 plc

I parmetrize the deferent zones in picture tree (each plc has it specific zone) and I affect for each alarme the zone which is the source of alarme

The objectif now, I want to make a group signalisation near each zone process screen in the headband of wincc runtime in order to know the source of alarme

For that I make the necessary configuration in OS project éditeur but without result

Please what is the right configuration to do in wincc in order to make it  working
