System alarms WinCC

Hi, I need to show an error when the HMI has lost its connection to the PLC, I have tried just showing the system alarms but there is alot of system alarms that I dont want to show.
Is it possible to just show some of the system alarms?

Im using WinCC flexible 2005 with a MP370 15 inch touch.

I am getting grumpy these days, but I so hate it when people call WinCC Flexible just "WinCC".

OK, I'll be nice and give you the solution:

Notice that you can interpret the "STOP" mode as "OFFLINE".

Thanks for the reply this should solve my problem.
