Problem withe the OPC-UA client in NI Vision Builder 2015 for Automated Inspection

Status: Under Consideration

This is a good point. We will investigate if we can add this capability for the next release. In the mean time, you can use a Run LabVIEW step to read/write specific items on your OPC UA Server from VBAI.

Thanks for the feedback,

Brad

Problem:

 When the OPC-UA client make a connection to the server, the client brows all items what he find at the server. In my case, I have more than 3000 Items. Then the software needs about 20 min to show the items. (I need the number of items, then the SPS is just from more systems)

When I start the aplikation, the used memory of the VB goes up to 1,990 MB and the soft ware have no reaction.

When I modify the OPC-UA server to 30 Items is no problem with the used memory.

Normaly when a client brows the Items, they don't look at all, they look only on the item what they need.

Is it posisble to modify the OPC-UA client from the VB that they look only to the needs items?

 

The Problem is in WIN7 32/64bit, Win10 32/64bit.

I need only the Vision Builder to evaluation of images of a camera.

I don't need Labview.

 

 

Best regards

Amend Harald

Would it be possible to send the hierarchy of OPC tags you are using? I made some optimizations to the code so a server that took 30 seconds to enumerate now takes about 1.5 seconds. It would be helpful to see the layout you are using so we can better understand if it's flat of has a lot of parents/children since there could be additional optimizations we could make if there is a lot of parent/children in your hierarchy.

Thanks
