Hello,

 

Please if someone could help me with this question...

We are using the OPC UA COM Server Wrapper (released by OPC Foundation at GitHub).

Basically I can use the wrapper with few items, but when I tried to load more than 500 items, the client just trace timeout's messages. I can´t monitore the items in this case...
If I connect to the Wrapper, browse and start monitoring some items, no problem, and I can added and monitore as much as I can....
But, if I start the OPC UA Client with a saved list (more than 500 items) .... I can´t monitore. I connect, it start and after some time I got a timeout error message.

Am I missing something basic? Please if someone could help i'd appreciate ... Thank You !

The wrapper is a sample and was never subjected to the testing required for a product used in production.

So issues with performance and reliability are not surprising.

From github Forum I got the answer fot this issue:

"....

@tukotech commented 8 days ago •
how does the item path looks like for your OPC DA server?
For example, DeltaV OPC server looks like this:
MODULE1/FB/PARAM.CV
The reason I am asking is that path separator should be configured on the wrapper correctly otherwise it will have to traverse the address space to look for the item. So for the above example, path separator is /
See link below for a fork I did and how it was configured:
https://github.com/wickedtuko/.....g.xml#L152

..."

This answer solved my question... my tag separator is dot "."
I changed the XML and everything worked fine.

This issue can be closed Smile
