Hello Carlos CES

If i do not know how is the correct syntax for the filter then I use a little trick:

-> show the configuration dialog in Runtime of your Alarm Control. then use a button in this screen where you use a VB Script and on Click use a msgbox to show the MsgSQL Filter property of your alarm control.

then in Runtime use the Filter dialog to "click your filter as needed", then press the button and read the syntax at the property. then you can use this in your scripts to dynamise the MsgSQL Filter property of your alarm control

or you check out this WinCC V7 FAQ:

its quite the same in WinCC Prof
