TreeView in PARA

[muthaseer]

Whether there are any performance limitation to create number of sub elements ( branches) in PARA TreeView.



Thanks,

Can you please describe more precise what the question is and what you want to do.

We need to create PARA structure having multiple hierarchies (parent and child). How many number of levels can we have so that there will not be any performance issue.

I do not know a limit for levels in a datapoint type structure.
As WinCC OA is internally working only with DP-IDs I do not think that it makes a (big) difference how many levels are defined.
A DP-ID only consists of the information for the type ID, the datapoint ID and the element ID. The number of levels is not part of the DP-ID.
The level information is only visible when converting the DP-ID to string.

How many levels will your datapoint type structure have?

Thanks Leopold,

There are eight levels of datapoint type structure. I hope there will not be any performance issue.

I'd suggest that you take a look at CNS and the 'CNS Editor'. It will allow you to display any tree structure you like.
I don't believe you can tell the PARA panel to display your CNS tree.
If you just want to display some simple data then you could consider building your own PARA 'look-a-like' panel based on a CSN tree

We have some datapoints with 5 levels, of the form System1:AAA.BBB.CCC.DDD.EEE, which para has no trouble with, except for the cosmetic issue that the field where the datapoint is displayed is too short to show the whole name (in WinCC V3.14, at least)

8 levels in the datapoint structure will not be a problem.
When resizing the PARA panel during runtime the space used for the treeview is changed as the PARA panel has a panel layout.
