wincc flex2008 pid faceplate

Hi all
I am trying to create a faceplate to set pid parameters for fb41 when I assign dynamic property I cannot pick a time for the data format then when I pick db41.ti as the tag for the faceplate it turns orange and warns me that tag is wrong data type does anyone know if I have to convert a dynamic property of say a real to the to the time format or how else can I set up an input field in a faceplate to set ti and td ?

For me it works fine, you have to put right type in object properties, as well as in tag, in tag editor.
