But, steel need answer for: How to get syntax (string) of already applied MsgFilterSql filter ?

In https://support.industry.siemens.com/cs/document/5668269/how-do-you-use-the-msgfiltersql-property-of-the-wincc-alarm-control-in-order-to-use-an-sql-instruction-to-filter-the-messages-to-be-displayed-?dti=0&lc=en-WW 

there is reference:

• Open the Object Properties of the Alarm Control.
• Under Properties > Control Properties you select the attribute "DefaultMsgFilterSQL".
• Now the correct SQL instruction is displayed in the "Static" tab.
• Copy this instruction to your script.

but I can't find anything like this in V14 professional.
