• DataObject-Lists got the extension ".obj.xml"
• Dataobject-Lists may contain different Dataobjects

• Create DataObject-Lists.
• Import DataObject-Tables from VisionNT.

Create a subfolder called "DataObjects" in the Project folder.

In the pull down menu ‘File’ of the toolbar - select "new".
In the opened window select the item “DataObjectList”.

ProcessVariable	yes
AlarmDataObject	no
SystemObjekt	yes
ana.Measuring Point	yes
bin.Measuring Point	yes

The DataObject is created.

• The system places a default name according the Object type. (PVn, SOn, AMpn, BMpn, Refn, Xobjn - n stands for the running number)
