Alarm Notification Software

I am looking for suggestions regarding Alarm Notification Software. I am trying to find something that works with a Siemens system. We have s7-400's with v6.0 WinCC.

I have looked into Win911, but it does not natively support siemens. You need to build a DDE link. Can anyone suggest something that works more or less out of the box?

Thanks!

Have a look at www.controlsee.com Don't know if it supports seimens "out of the box" you will have to check that

It doesn't have direct drivers, but at least it can do OPC.

Thanks for the tip!
